Hello!
I have a problem when using a hidden field to send a value to the server.
Below you can see my code in simplyfied versions.
What I'm trying to do is:
1. The user browses for a picture at the network from their computer using
control File1.
2. The user clickes the button Commit picture (with id CliBtn)
a. The script is running at the client to get the sharename of the file
selected
b. The script should update a picture shown (the code below just shows
the label with the path)
c. The code-behind should then save all values in a database.
The problem appear when I'm trying to set the value to the hide control, so
I am doing something wrong.
I'm not so used to web developing, so please give me some help here, with
code please.
Regards Magnus

In particular fso is not supposed to work without tweaking security
settings. ARe you sure itjust doesn't fails silently...
Also you always change the value of the "hide" field when the page loads...
Try to do not "if (!Ispostback)"...

Hello and thanks for your answer.
Well, I thought fso was not a common way to solve this, but since this is
for a Intranet, I think I can theak the security anyway. If you have a
better solution for this issue I'll be glad to here it.
I'm not sure what silent failure does mean, but I think that is what I get.
I get no error message, but the alert row is never executed when the
hide.value = javatext is run.
The problem does not appear when working with fso. It appears when trying to
set the hide object.
I am familiar to the (!IsPostBack) command, so I will take care of that in
my full code.
My code in this forum is shrinked.

Ok, so this line is never executed.
Check if the fso object is set. Do you have yet tweaked security ?
If I remember when security is not tweaked , it fails without any warning
(as anyway it 's not supposed to work).
What do you want to do ? You can use an input type=file to get the name
server side even if you don't want to upload this file. This way you
wouldn't need to copy this value in an hidden field.
Also I don't really see how it works. The server could perhaps not have the
same netwrok path available.
Depneidng on what you wan to do with this file, I would upload it server
file to do the intended processing...
Good luck

Set bold, italic, font type etc on the textbox(multiple)?
I have problem to find the code to bold, italic, get the font type or set the size of font on the texbox. i develop forum site. when user want to send message, they need to fulfill the title and content. what i want to do same like in hotmail.com (the flexible textbox when to submit message). ThanksHi, seethis site.
Thursday, March 29, 2012
set cell color while rendered in a datagrid
I use the code: <asp:BoundColumn DataField="EFF_END_DT"
SortExpression="EFF_END_DT" HeaderText="Effective End"
DataFormatString="{0:d}">
<ItemStyle ForeColor= '<% # MyColor(
DataBinder.Eval(Container.DataItem, "EFF_END_DT"))%>'></ItemStyle>
</asp:BoundColumn>
to have red date is it is over and blue if not!
But I get an error:
Compiler Error Message: BC30676: 'DataBinding' is not an event of

how can I resolve this?i think your trying to user the OnItemDataBound method
In this method you can access each row of your datagrid, and from there
determine if the date should be read or not.
in the .aspx page
<asp:DataGrid id="MyGrid" OnItemDataBound="MyGrid_OnItemDataBound" ....
then in the .cs page
public void MyGrid_OnItemDataBound(object Sender, DataGridItemEventArgs e)
{
//From here you can access your bound column and set the colors

Thanks! that was helpful.
Would you know why if the results is 2 rows the event fires 4 times
2 times with the value I axpect an 2 with " "
my vb is:
Private Sub DataGrid1_ItemDataBound(ByVal sender As Object, ByVal e As
System.Web.UI.WebControls.DataGridItemEventArgs) Handles
DataGrid1.ItemDataBound
Debug.WriteLine(e.Item.Cells(6).GetType.ToString) 'always
System.Web.UI.WebControls.TableCell
Debug.WriteLine(e.Item.Cells(6).Text)
End Sub
End Class

Set checkbox in datagrid manually/through code
I have a numeric Oracle field which stores -1 for true and 0 for
false. I am trying to populate a checkbox in a datagrid. In my SQL
statement, I used the Decode function so that when it populates the
dataset that I would store the string 'true' and 'false' rather than a
numeric value. I did this because I thought it would make it easier
to actually set the value in the checkbox. Anyway, I bind the dataset
to the datagrid. In my HTML code, the checkbox is contained in a
templatecolumn:
<asp:CheckBox id="chkStrainerFuelLine" runat="server" Checked='<%#
(bool) DataBinder.Eval(Container.DataItem,
"strainer_on_fuel_line_bool") %>' Enabled="False"></asp:CheckBox
However, this will not work. It complains that "Specified cast is not
valid."
I have even tried it without the "(bool)" cast and it still didn't
work.
The data in my database has the value stored as either a -1 or 0. In
either case, I just want to set the check box to checked or unchecked.
I was even wondering if I needed to use one of the d atagrid's events
to do this.
Any ideas or help is appreciated.
Thanks,
MartySome suggestions
Try using a helper function to interpret your -1 or 0 instead of adjusting your recordset to return true or false
In your codebehind
protected bool GetCheckBoxSetting(object myObj
int myInt = Convert.ToInt16(myObj)
return (myInt == -1)
Then in your aspx
<asp:CheckBox id="chkStrainerFuelLine" runat="server" Checked='<%
GetCheckBoxSetting(DataBinder.Eval(Container.DataI tem, "strainer_on_fuel_line_bool")) %>' Enabled="False"></asp:CheckBox
If returning bool doesn't set the checkbox checked property correctly then try returning a string from GetCheckBoxSetting method
protected string GetCheckBoxSetting(object myObj
int myInt = Convert.ToInt16(myObj)
if (myInt == -1
return "true"
els
return "false"

Set Code Behind Property from Javascript / link?
I got a property in my code behind, nl "Language" with Get and Set accessors.
On my form I want to put a link (html, not asp) who's target is a javascript in my <head> section.
Then I want this Javascript to set the value of my Language property, and in the Set accessor for the property, do some stuff.
Is it possible to set the property in the code behind from your page? Maybe i should just use an asp label running on the server, but I'm trying to see how far i can stay away from anything causing a postback.The Language property exists in the codebehind. You do realize that at some point, you will have to have a postback so that the property can be assigned that value and perform whatever actions it wants to perform. Get it?
You will eventually have to use some sort of a server-side control for this. Here's what I would suggest.
Add a hidden field to your page. When the user clicks on the hyperlink, the javascript function assigns a value to that hidden field. When the page posts back, in the page load event, assign the value of the hidden field to your property. Then let the property do whatever with it.
No, you cannot avoid the postback as far as you've described your setup.
Actually I was stupid anyhow. When hte language change, I got to reload the form with the different language.
I never use hidden fields though. Nevermind
Thanks for reply M.
No prob.
Just been thinking.
What if one do want to set a code behind property from the page?
What if you do want to call a code behind fucntion from a javascript, sitting in hte head section, called by for instance a link clicked?
The answer to your first question is above ^^
The answer to your second question is a little complex. You will need to use javascript to force a postback. You can do this in one of two ways. For example, if you want to call a button's click event, you can call it like
document.getElementById('buttonid').click();
The second way to do this is quite generic. You can use javascript to force a postback.

Set columns in dataGrid
I have this code:
//Perform search
xslt.Transform(new XPathDocument(Server.MapPath("TIPTREECAT.xml")), xslArg,
sw, null);
StringReader sreader = new System.IO.StringReader("<root>" + sw.ToString() +
"</root>");
this.dataSet.ReadXml(sreader);
this.DataGrid.DataSource = dataSet;
this.DataGrid.DataBind();
How can I change colums I want to show in the grids? I want to show less
columns then there are in an xml data.
Thanksset the AutoGenerateColumns property to False. Then create column templates
for each column you want to display. The simplest version if this is the
BoundColumn:
<asp:BoundColumn DataField="FName"></asp:BoundColumn
You can also right-mouse click the datagrid and go to Property Builder.
This utility will help you set up your datagrid.

Set controls to nothing when finished?
Hello,
I recently saw some example code that looked similar to the following...
Is there a reason why the literalBr control was set to nothing after adding it to the panel? Does it cause memory usage to go up if you dont set controls to nothing after creating them programmatically?The garbage collector will take care cleaning up literalBr in this case. Setting literalBr to nothing is a waste of time. SeeProgramming for Garbage Collection for more details.
I recently saw some example code that looked similar to the following...
...
Dim literalBr As New System.Web.UI.LiteralControl()
literalBr.Text = "<br>"
literalBr.ID = "anId"
Panel1.Controls.Add(literalBr)
literalBr = Nothing
...

Set css class on list box option
Hi,
Thanks for the replies.
I want to programatically set the css class on a single list item. I tried the following code but it does nothing...
<html>
<script language="VB" runat="server"
Sub Page_Load(Src As Object, E As EventArgs)
categories.Items(0).Attributes.Add("class", "option.primary")
End Sub</script
<style>
.primary {background-color:green;color:red; }
</style
<body>
<form runat="server">
<asp:listbox id="categories" Runat="server" SelectionMode="Multiple" Rows="6" Width="400">
<asp:listItem>Item 1</asp:listItem>
</asp:listbox>
</form>
</body>
</html>
Does anyone know how to achieve this?
WT.use the "cssclass" property of the listbox, then you can set it without doing the attributes.add thing.
<option> elements do not have class attributes, but it *is* strange that it doesn't write it out anyway. If you look at the rendered HTML, it probably reads:
<select name="categories">
<option value="Item 1">Item 1</option
That is because, as said, option elements don't have class attributes. Additionally, you're specifying "option.primary" where really the css class you want to use is "primary". If you want to add the class to the whole categories listbox, you could. And an easier way is to use this syntax:
categories.CssClass = "primary"
Which will work just the same as:
categories.Attributes.Add("class","primary")
Thanks for the replies.
I presume that the listItems not rendering their attributes must be a bug.
Looking at the source for the ListBox control, it doesn't appear to be rendering the attributes of its list items. Thus, I'll override the 'RenderContents' method or something and get the attributes rendered.
I think it is a bug too,
but the class browser indicated that the attributes property of the ListItem is readonly which would explain the attributes not being added to the listitem... maybe it is by design.

TextBox1.Text = dtmToday
TextBox2.Text = dtmTodayThanks, but that didn't work. Your code just took the date back 7 days
INCLUDING WEEKENDS. If the textbox is 12/11/06, it is now 12/4/06. If I
change the code to -1, it will go back one day but it does not disregard the
weekends. How do you disregard the weekends?

Set DIV text in code behind
if i want to set the text inside a div (or other properties like "class") from my code behind, as what to i declare it? htmlgenericcontrol? If so, what attribute do i set.
html:
<div id="divtest" runat=server></div>
code behind:
protected System.Web.UI.HtmlControls.WHAT?? divtest;
...
...
divtest.WHAT?? = "seems to work";Html part is fine. After you've created it, look at it in the design view, save the page, then go to the codebehind, you should be able to see an html div control (some name)... set its innerText property.
hmmm...not so sure
I always have to code the "protected htmlcontrol whatever mycontrol" myself in my project. VS never do it for me. SOMETIMES, VS will add this for me for asp.net controls though.
Maybe something to do with the fact I ALWAYS hand code my pages...never drag and drop onto form...
...aaah...stupid me..let me drag some html controls onto the form and see what VS do for me... sorry..always talk to myself huh?
It's a VS 2003 bug that I discovered much to my consternation when VS 2003 had just come out. Surprisingly, it was addressed by nobody. Everyone thought it was a feature rather than a bug, I even asked MS developers about it, and they did fix it in VS 2005 but they mentioned that very few people ever brought it up regarding VS 2003.
The workaround was that you have to save the ASPX page before going to the codebehind so that the control's code was added to the codebehind file.

set field to dbnull?
In the following code the line: row("OrderDate") = DBNull is invalid. But,
how can I set the field to DBNull?
Thanks,

Set Focus
Hi, i'm working on MS visual.net using C# asp.net web application. Can someone help with the code to set focus on a textbox when the page is load?
I tried many ways including the examples in metabuilders.com but just couldn't do it.
Wat is the code that need to be insert during pageload.
Thanks for your input. But where do i place this code in? is it in the pageload part? Because there is an error message.
Daisy, why not use theonblur event
I tried many ways including the examples in metabuilders.com but just couldn't do it.

Hope someone will help me with this. Thanks.
RegisterStartupScript("myfocus", "<SCRIPT>document.all." + TextBox1.ClientID + ".focus();</SCRIPT>");Thanks for your input. But where do i place this code in? is it in the pageload part? Because there is an error message.
Thank you.
what is the error?
pls post code and error.
the same
in vb .net
'write this function in side server code
Private Sub mySetFocus(ByVal ctrl As System.Web.UI.Control)
Dim strFocus As String
strFocus = strFocus + "<SCRIPT language='javascript'>"
strFocus = strFocus + "document.getElementById('" & ctrl.ID & "').focus();"
'if want select
strFocus = strFocus + "if ( document.getElementById('" & ctrl.ID & "').select != null ){document.getElementById('" & ctrl.ID & "').select();}"
strFocus = strFocus + "</SCRIPT>"
RegisterStartupScript("mySetFocus", strFocus)
End Sub
'call whit control for focus
call mySetFocus(txtControl)
Is there any way that we can do this without using javascript?
AFAIK, that's a client side / browser issue,
so Javascript can utimately do this in ASP.NET
hi ChinHan:
If you want set focus to a textbox when the page load,
if so txtbox is a textbox control that if you want , you can do like this
<body onload="javascript:document.all.txtbox.focus();"></body>
Thanks.. rox.scott. manage to solve the problem.. Thanks a lot.
I have another qns.. after i enter the data in the textbox, i have a search button to find the information.. but i can't press the ENTER key to search it. i need to use a mouse click.. how do i solve this.. In windows form there is no problem but in asp.net web application this problem occurs..
Thanks!
Hello,
that is another task where you can use javascript to accomplish this. In my opinion one of the best way to solve this has made Janus Kamp Hansen with his script. I want to show you this in the following example:
Public Sub DefaultButton(ByRef Page As System.Web.UI.Page, ByRef objTextControl As TextBox, ByRef objDefaultButton As Button)Put this code in your code-behind module and in the page load event you can define the default buttons for the ENTER-Key like in the following sample:' Sets default buttons.
' Created by Janus Kamp Hansen - http://www.kamp-hansen.dk
Dim sScript As New System.Text.StringBuilder()sScript.Append("<SCRIPT language=""javascript"">" & vbCrLf)
sScript.Append("function fnTrapKD(btn){" & vbCrLf)
sScript.Append(" if (document.all){" & vbCrLf)
sScript.Append(" if (event.keyCode == 13)" & vbCrLf)
sScript.Append(" { " & vbCrLf)
sScript.Append(" event.returnValue=false;" & vbCrLf)
sScript.Append(" event.cancel = true;" & vbCrLf)
sScript.Append(" btn.click();" & vbCrLf)
sScript.Append(" } " & vbCrLf)
sScript.Append(" } " & vbCrLf)
sScript.Append("}" & vbCrLf)
sScript.Append("</SCRIPT>" & vbCrLf)objTextControl.Attributes.Add("onkeydown", "fnTrapKD(document.all." & objDefaultButton.ClientID & ")")
Page.RegisterStartupScript("ForceDefaultToScript", sScript.ToString)End Sub
DefaultButton(Me.Page, Me.txtField, Me.cmdDefaultButton)For any explanation please look at the web-address in the code...
HTH,
If you are using ServerSide button control, then if you have your code in buttonX_Click event then on click on that buitton only that event fires.
But, there is an alternative solution for this.
If you enter data in TextBox and press Enter, then again Page_Load event will fires as my understanding.
So what you have to do is
on Page_Load check if the textbox has value or not, if the textbox has value then call your button_click event
Ex:
on page load event
If len(textbox1.text) > 0 Then
Button1_Click(sender,e)
End if
this kind of logic might helps to your problem!
hi kbrocksi SEC.. i'm working on a C# project. Do u have it in C#? thanks!
Hi, I am having the opposite problem...I have multiple textboxes on my page, and I have set focus to the first one...but when the user presses the enter key it fires the btnEdit_Click event...causing all kinds of issues. How do I stop it from running the button click and make it set focus to the next string??
I've tried capturing the keypress event of the form, to simply move it to another control, but that doesn't seem to work either.
here's the code:
frmMain.Attributes.Add("onkeypress", "frmMain_keyPress;")Dim sbJavaFunction As StringBuilder = Nothing
sbJavaFunction = New StringBuildersbJavaFunction.Append("<script language=""javascript"">function frmMain_keyPress()")
sbJavaFunction.Append("{frmmain.lblTest.Text='hi';")
sbJavaFunction.Append("if (event.keyCode == 13){")
'sbJavaFunction.Append("event.cancelBubble = true;")
'sbJavaFunction.Append("event.returnValue = false;")
sbJavaFunction.Append("document.forms[0].txtTotalPairs.Focus;")
'sbJavaFunction.Append("document.forms[0].txtTurn_TextChanged();")
sbJavaFunction.Append("}}</script>")
Page.RegisterClientScriptBlock("HandleEnterKey", sbJavaFunction.ToString())
sbJavaFunction = Nothing
any ideas would be helpful!
Chinhan...here is the translation of the above code:
private void Page_Load(object sender, System.EventArgs e)
{
DefaultButton(this.Page, this.txtField, this.cmdDefaultButton);
}public void DefaultButton(Page Page, TextBox objTextControl, Button objDefaultButton)
{
// Sets default buttons.
// Created by Janus Kamp Hansen - http://www.kamp-hansen.dk
System.Text.StringBuilder sScript = new System.Text.StringBuilder();sScript.Append("<SCRIPT language='javascript'>\n");
sScript.Append("function fnTrapKD(btn){\n");
sScript.Append(" if (document.all){\n");
sScript.Append(" if (event.keyCode == 13)\n");
sScript.Append(" { \n");
sScript.Append(" event.returnValue=false;\n");
sScript.Append(" event.cancel = true;\n");
sScript.Append(" btn.click();\n");
sScript.Append(" } \n");
sScript.Append(" } \n");
sScript.Append("}\n");
sScript.Append("</SCRIPT>\n");objTextControl.Attributes.Add("onkeydown", "fnTrapKD(document.all." + objDefaultButton.ClientID + ")");
Page.RegisterStartupScript("ForceDefaultToScript", sScript.ToString());
}
Daisy, why not use theonblur event

Set focus and cursor at end of text?
I use this code to set focus to a textbox when I load a page:
private void SetFocus(System.Web.UI.Control ctrl)
{
string s = "<SCRIPT language=\"javascript\">document.getElementById('" +
ctrl.ID + "').focus()</SCRIPT>";
RegisterStartupScript("focus", s);
}
I would also like the cursor to be positioned at the end of the text field.
Using only the above code, the cursor is positioned at the beginning of the
textbox even if there are some text present in the field.
How can I position the cusrsor at the end of the text?
OlavOlav,
Here we go:
Create a new function in your <head> tag in the HTML section:
function SetEnd (TB)
{
if (TB.createTextRange)
{
var FieldRange = TB.createTextRange();
FieldRange.moveStart('character', TB.value.length);
FieldRange.collapse();
FieldRange.select();
}
}
Create a new onfocus JavaScript event in your asp text box tag (asp:textBox)
that calls the SetEnd function above:
<asp:textbox id="TextBox1" runat="server" Width="65px"
onfocus="SetEnd(this)">Existing text</asp:textbox
Make sure you keep your existing code that calls the SetFocus function as it
is:
private void SetFocus(System.Web.UI.Control ctrl)
{
string s = "<SCRIPT language=\"javascript\">document.getElementById('" +
ctrl.ID + "').focus()</SCRIPT>";
RegisterStartupScript("focus", s);
}
Don't forget to call the above SetFocus() function in your Body tag on page
load ....( <body onload="SetFocus()"> )
Good luck!

Mohammad Samara.

Set Focus to control
Hello,
I have a content page (I am using a Master Page) that has a control
"ddlRequestType".
In my code behind, I am using the following to create an image and assign
JavaScript to it that will set the focus to the control "ddlRequestType":
If Trim(Me.ddlRequestType.SelectedItem.Text) = "None Selected" Then
strValidateText &= _
"<tr>" & _
"<td width=200><div align=left>Request Type</div></td>" & _
"<td width=400><div align=left><A HREF=#
ONCLICK=ddlRequestType.focus()>" & _
"<IMG SRC=../../images/art_dbflash_go.jpg BORDER=0 ALT=GoTo>" & _
"</div></td>" & _
"</tr>"
strValidateForm = "Validation Error"
End If
However, when I click on the image, I get the following error:
ddlRequestType is undefined.
Any help with this would be appreciated.
Thanks in advance,
sck10Hi,
Try:
document.getElementById('ddlRequestType').focus(); or
Form1.getElementById('ddlRequestType').focus();
Good luck! Ken.

I suggest you to don't use direct id or name for referencing javascript
object, try this:
HREF="java script:document.getElementById('ddlRequestType').focus()"
However i tink is better don't use string for create controls, try add
controls using TableCell,TableRow,ImageButton.
This is a simple example:
Dim tempRow as new TableRow()
Dim tempCell as new TableCell()
Dim myButton as new ImageButton
'Assign properties to rows and cell
myButton.attributes("onclick")="document.getElementById('ddlRequestType').fo
cus()"
tempCell.Controls.Add(myButton )
tempRow.Cells.Add(tempCell)
'add your row to your table rows

HREF="java script:document.getElementById('ddlRequestType').focus()"
However i tink is better don't use string for create controls, try add
controls using TableCell,TableRow,ImageButton.
This is a simple example:
Dim tempRow as new TableRow()
Dim tempCell as new TableCell()
Dim myButton as new ImageButton
'Assign properties to rows and cell
myButton.attributes("onclick")="document.getElementById('ddlRequestType').fo
cus()"
tempCell.Controls.Add(myButton )
tempRow.Cells.Add(tempCell)
'add your row to your table rows

Set Focus to control
Hello,
I have a content page (I am using a Master Page) that has a control
"ddlRequestType".
In my code behind, I am using the following to create an image and assign
JavaScript to it that will set the focus to the control "ddlRequestType":
If Trim(Me.ddlRequestType.SelectedItem.Text) = "None Selected" Then
strValidateText &= _
"<tr>" & _
"<td width=200><div align=left>Request Type</div></td>" & _
"<td width=400><div align=left><A HREF=#
ONCLICK=ddlRequestType.focus()>" & _
"<IMG SRC=../../images/art_dbflash_go.jpg BORDER=0 ALT=GoTo>" & _
"</div></td>" & _
"</tr>"
strValidateForm = "Validation Error"
End If
However, when I click on the image, I get the following error:
ddlRequestType is undefined.
Any help with this would be appreciated.

Thanks in advance,
sck10Hi,
Try:
document.getElementById('ddlRequestType').focus(); or
Form1.getElementById('ddlRequestType').focus();
Good luck! Ken.

Set headertext in datagrid programatically
I create a datagrid using the Web Forms Toolbox
The dataadapter,dataset and databind() code runs in a button eventhandler
The headertext is currently determined by the column names of my SQL select
statement there.
How can I change the headertext programatically in the codebehind? ... I do
n't want to change the preexisting code if at all possible.in your itemdatabound event handler, you can test for the headeritem and
then use the text property attached to the cell object to change the text
e.item.cells[4].text = "vapor"

Set href for <link tag
I need to dynamically set the href attribute for the <link> tag at run time
for my pages. I thought I saw code using the asp:placeholder to give the
code-behind a place to update the html control with a specific href setting.
Any ideas?
ThanksThis sets technique sets the Title programmatically but you might be able to
rejig it to do a <link>

Hi,
Give the <link> tag id="lnk" (can be anything) and runat=server attributes.
From code-behind, use the Attributes property, like normal server-side
controls, to add attribute values:
lnk.Attributes.Add ("rel", "stylesheet")
lnk.Attributes.Add ("href", "primary.css")
HTH.
