Set browser in PrinPreview state on page load

Hi, Can i set the clients browser programmatically to PrintPreview state (File->Print Preview) when the client clicks the button print?

I don't want to use Crystal nor Report Viewer for some reasons

regards

Thanks in advance! More Power!

Hi,

As far as I know, it's impossible because you have to manipulate IE from client. If so, that means you have access to control windows process, then that's very dangerous. What's more, in fact, there are little APIs for us to control IE's function, especially such thing.

HTH

Hey Dfox,

Unfortunately asp.net works server side, so you can't change client side behaviour.

Keep up the good programming!

set focus

How can I set focus to a txtbox in the page load handler?Yes it is possible , in several ways, but the most effective is:

<FORM NAME="myFormName">
<INPUT ITEM="text" NAME="myTextField">
</FORM>
<SCRIPT LANGUAGE=JAVASCRIPT></SCRIPT>

It's client side script...
what if it's a web control instead of a HTML control?
Sorry, send you the wrong code!
This will work, except on self-made usercontrols...

just add a 'imports system.text' line before your class dec.

add this to your startup:

Dim strBuilder As StringBuilder = New StringBuilder()

strBuilder.Append("<script language='javascript'>")
strBuilder.Append("function setFocus() {")
strBuilder.Append("document.getElementById('TextBox3').focus();}")
strBuilder.Append(" window.onload=setFocus;")
strBuilder.Append("</script>")
RegisterClientScriptBlock("Focus", strBuilder.ToString)

Good luck!

Tim.
thanks..

Set Focus

When i load a form and the user selects an item from a dropdown list i want to set focus to another control. In standard vb and standard vb.net i can do this. Anyone know how to do this asp.net?... any help would be greatly appreciated

Thank youYou need to add some clientside JavaScript code in the form of an onchange event handler.
OTTOMH, something like:

DDL.attributes.add("onchange","document.getElementById('controlId').focus()")

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!

Regards,

Mohammad Samara.

Set focus on page load

Hello,

This is probably super simple but I can't figure out how to set the initial focus on an aspx page. I have a text box control that I would like to be the default focus on page load, how do I do this?

Thanks for any help

-SI think this might be the simple way but only good for IE:


<asp:TextBox id=TextBox1 runat="server"></asp:TextBox>
 <SCRIPT>window.document.all["TextBox1"].focus()</SCRIPT>

Please see below thread, it has related info on it

Set focus to a textbox on page load

I am new to ASP/ASP.NET so kindly be gentle. When my index.aspx page
loads, I need the focus to be on one of the textboxes called
txtUserName.

I come from a VB background, so expecting the obvious, I go to the
Page_Load event of the index.aspx page and try to write
txtUserName.SetFocus but I see there isn't a SetFocus method for the
System.Web.UI.WebControls.TextBox class.

What's the way to set the focus to a textbox on the page load in
ASP.NET?It's a client-side task. You need to call javascript focus() method on the
element you want to set focus on.

you can write a function something like this and use it when u need them.

protected void SetFocus(Control controlToFocus){
string formName = GetFormName(controlToFocus);
string jsString="<script language=javascript>document." + formName +
".elements['" + controlToFocus.UniqueID + "'].focus();</script>";
if(Page.IsStartupScriptRegistered("SetFocusToSearch")==false)
Page.RegisterStartupScript("SetFocusToSearch",jsString);

Hope this helps.

As the last post adviced this should do the trick:-

Private Sub SetFocus(ByVal ctrl As Control)
' Define the JavaScript function for the specified control.
Dim focusScript As String = "<script language='javascript'>" & _
"document.getElementById('" + ctrl.ClientID & _
"').focus();</script>"

' Add the JavaScript code to the page.
Page.RegisterStartupScript("FocusScript", focusScript)
End Sub

Hope this helps

Set Image Control to Bitmap

Hello All, want to be able to pull images from the database and load them
into a bitmap through a stream which I have working. I then want to take
the bitmap and load it into a Image control without haveing to save the
bitmap as a file. Is this possible? Currently, I just display the bitmap
by calling Bitmap.save however, if users do not know to click the image they
can not see the full size. If I can create a bitmap from the stream I know
the size so I can set the properties of a image control and then display the
bitmap in the image. Does this make since or am I going about this the
wrong way? So in a nutshell, I am pulling images from a DB and want to
display the full size without having to actuall save the image to a file.
Any pointers?
TIAYou can make an mypage.aspx page that returns bitmap (not HTML)
1. You need to set ContentType = "img/gif"; or (jpg)
2. You need to set ContentLength to the size of the image
3. Use Response.BinaryWrite to output the image. Or since Response is a
Stream you can do Bitmap.Save(Response);
in your HTML you write <img src="http://pics.10026.com/?src=mypage.aspx">
PS: It's more efficient to use handler for that task. mypage.ashx. But aspx
will work too if you fill more comfortable with aspx.

Your page can have an Image control on it, and that Image control can point
to another page (or handler) that retrieves the image.

Hi,

Does anyone know how to populate the maxlength property of an asp:textbox on page load?

I'm getting the value from the my config table in my DB

When I try setting myControl.MaxLength=10 in the onload event
It's not written to the control and when I enter text I'm not restricted at all

I've also tried

<asp:textbox id="Abstract" Runat="server" Wrap="True" Rows="11" Columns="45" TextMode="MultiLine" maxlength="<%=SummaryLimit%>"></asp:textbox>

' And

<asp:textbox id="Abstract" Runat="server" Wrap="True" Rows="11" Columns="45" TextMode="MultiLine" maxlength="<%=Convert.ToInt32(SummaryLimit)%>"></asp:textbox>
Geting error - <%=SummaryLimit%> is not a valid value for Int32.
And
<%=Convert.ToInt32(SummaryLimit)%> is not a valid value for Int32.

SummaryLimit Value is declared and assigned as an Int32
Dim m_iSummaryLimit As Int32 = 250

Public Property SummaryLimit() As Int32
Get
Return Convert.ToInt32(m_iSummaryLimit)
End Get
Set(ByVal Value As Int32)
m_iSummaryLimit = Convert.ToInt32(Value)
End Set
End PropertyThe textbox control when in multiline mode actually renders as a HTML textarea therefore on a textarea there is no maxlength property so maxlength does not work. One of the ways to control this is to use javascript instead.
Basilisk,

Thanks for that, just wasted the whole morning trying to get it working.

Cheers Al
I did want to pipe in and say that when you use the following:

<%= ... %>

in an item tag, you need to surround it with single quotes - ' - and not double quotes - " -.
Lord Rat,

Thanks, feel free to pop out of your cave with useful tips like that at anytime :D
