I am developing a data driven website in visual studio .net 2002 using
Visual Basic and APS.

I am trying to jump to a specific text box when a page loads. I can
Set the tab index to 1 and achive this by hitting the tab key but am
wanting this to load with the cursor on the specified text box.

homebuilder-ga,

Interesting question! Here's your answer:

onload="javascript:document.all.MyControl.focus()" where MyControl is the ID
of the control to catch focus.

[VISUAL BASIC]
' <summary>
' SetFocus
' Set Focus to a web control
' </summary>
' <param name="System.Web.UI.Control ctrl"></param>

Private Sub SetFocus(ByVal ctrl As System.Web.UI.Control)
	Dim s As String = "<SCRIPT language='javascript'>document.getElementById('" 
		& ctrl.ID & "').focus() </SCRIPT>"
	RegisterStartupScript("focus", s)
End Sub 

Calling SetFocus( )
	Me.SetFocus(Me.TextBox1)

Finally, one more approach. This C#, but I am sure you can understand the concept:
this.Controls.Add(new LiteralControl("<Script Language=javascript>"));
this.Controls.Add(new
LiteralControl("document.forms[0].elements[MyControl].focus()"));
this.Controls.Add(new LiteralControl("</Script>"));

I hope this answer solves your problem.

<HTML>
<HEAD>
</HEAD>

<BODY>
<FORM onsubmit='return false' NAME=myForm>
<INPUT NAME='myInput'>
</FORM>
<script>
document.myForm.myInput.focus()
</script>
</BODY>
</HTML> 
You need to wrap the input in a form element.
The return false on the on submit is needed for not submitting the
form, if you use it as a non-form control, otherwise if the text big
is in a form that must be submitted, remove it.

onload="javascript:document.all.MyControl.focus()"

I used this one, but IE in XP SP2 (not G-toolbar though) and NS block
it as a Pop-up, is their another way?

(apart from VB and C# as they are over my head)
