Set focus on null fields!

Hi,
I have a login form and I have two text boxes in it and the user is required to enter data in the textboxes.If they fail to enter data in any one of the text box and hit the submit button I would like for the cursor to setfocus on the empty text box for the user to enter the data.How would I do this in asp.net.If not would I be able to write Javascript and call the function and where would I call the function.COuld someone expalin how to accomplish this.I do know how to set focus on the first textbox when the page loads up.But I am lost when I am required to setfocus the cursor at the empty text box for user entry?try this:

string strScript = null;
strScript = "<script language=javascript> document.all('TextBox1').focus() </script>";
RegisterStartupScript("focus",strScript);

HI Azam,
I am getting a synatax error. Do I have to declare strScript in my Dim?Also is this a subroutine all by itself or is it part of another subroutine(like page_load)?
Hi,

try to put this code on the Server Side Button Click event.
HI Azam,
I tried your way but I get the error message that says strString is not declared.Also in your code the "TextBox1" would be the ID for the text boxes I have in my project Right?
declare strString as a string variable.

like this:

string strString = "whatever"; // C# syntax

Yes "TextBox1" is the id for the textboxes you have in yr project.
HI Azam,
I am doing this in VB .would the codes be any different if it is VB.
Only syntax.

Here is aC# to VB.NET converter.
HI Azam,
If I did it by your codes would I be able to set focus on the null fields or just the first text box.I am so many error message and that's why I could not see the results.Could you please mail me regarding this?Thanks.
Hi Picky,
Thanks.That is a cool tool!

Set focus on the field (Form validation in ASP.NET)

Hi,
I have a problem and really need your help. In my web page ASPX, I have
some text fields to accept data from users. I did form validation like this
:
<td class="dataTD" style="HEIGHT: 30px" width="100">
<asp:TextBox id="txtFUEL_ISSUED1" style="Z-INDEX: 100; POSITION: absolute"
runat="server" Width="107px" BorderColor="Transparent"
autoPostback="true"
OnTextChanged="txtFUEL_ISSUED1_TextChanged"></asp:TextBox>
</td>
<td class="dataTD" style="HEIGHT: 30px" width="100">
<asp:CompareValidator id="CompareValidator1"
runat="server" Width="90px" ControlToValidate="txtFUEL_ISSUED1"
ForeColor="LightCoral" ErrorMessage="Please enter a number!"
Operator="DataTypeCheck" Type="Double"></asp:CompareValidator>
</td>
In the txtFUEL_ISSUED1_TextChanged, I checked if data on this field is valid
or not. If it's valid then I add this value in the TOTAL field. I'd to to
set focus on the next field when this data IS VALID, OR focus on this field
when data IS NOT valid . Can you help me ? Thanks in advanceI suggest you upgrade to ASP.NET 2.0, which has new features that satisfy
all your requests.
I hope this helps,

Steve,
I have some questions:
1- There are some versions ASP.NET 2.0 from the www.asp.net web site :
a- .NET Framework 2.0 SDK x86,
b- .NET Framework Version 2.0 Redistributable Package (x86)
c- .NET Framework 2.0 SDK x64
d- .NET Framework Version 2.0 Redistributable Package x64 (64
Bit)
e- .NET Framework 2.0 SDK IA64
f- .NET Framework Version 2.0 Redistributable Package IA64
(64 Bit)
Which one do you suggest me to download ?
2- After downloading, do you think this code will work OR I should
change something ?
Sub txtFUEL_ISSUED1_TextChanged(sender As Object, e As EventArgs)
Dim strScript As String = "<script language=JavaScript>"
If IsNumeric(txtFUEL_ISSUED1.text) OR
txtFUEL_ISSUED1.text="" Then
Dim aValue as double=0.0
If IsNumeric(txtFUEL_ISSUED1.text) Then
aValue=CDBL(txtFUEL_ISSUED1.Text)
End If
' ADD the value to the TOTAL field
ViewState("FUEL_ISSUED_Total") =
ViewState("FUEL_ISSUED_Total") + aValue - ViewState("FUEL_ISSUED1")
txtFUEL_ISSUED_Total.text=FormatNumber(ViewState("FUEL_ISSUED_Total"),
2, , ,TriState.True)
ViewState("FUEL_ISSUED1") = aValue
strScript = strScript &
"document.form1.txtFUEL_ISSUED2.focus();" 'FOCUS on the next field
Else 'FOCUS on the current field
strScript = strScript &
"document.form1.txtFUEL_ISSUED1.focus();"
End If
strScript = strScript & "<" & "/script>"
If (Not Page.IsStartupScriptRegistered("clientScript")) Then
Page.RegisterStartupScript("clientScript", strScript)
End If
End Sub

If you have a 32-bit machine ( a standard Intel or AMD )...
If you want the very minimum necessary to run ASP.NET 2.0,
get .NET Framework Version 2.0 Redistributable Package (x86)
If you want the QuickStart Tutorials, extra tools *and* ASP.NET 2.0,
get .NET Framework 2.0 SDK x86
If you have a 64-bit machine, your choice may vary depending on the cpu.
The code you posted should run on any of the 5 choices.
