You cannot. Instead, you'll have to submit the page with a hidden value set somewhere, so that vb.net can look at it and perform appropriate actions.

This is not possible, as far as my knowledge goes. You have to separate the Javascript function in the aspx page and store the return value in some hidden field. Call the javascript method in the button click using attributes.add and check for the return value in the hidden field in the event handler for the button.
Hope this helps.
Everything I code, is a piece for Museum.

I wonder how many charact
Re: HOW to write Javascript in VB.NET?
Code:
<head>
<meta...
...
...
<script language="javascript" type="text/javascript">
function DoSomething()
{
if (confirm("Do you wish to continue?"))
{
document.getElementById('hiddenChoice').value = 1;
document.forms[0].submit;
}
else
{
document.getElementById('hiddenChoice').value = 0;
document.forms[0].submit;
}
}
</script>
</head>
<body>
<form id="Form1" runat="server">
<input type="hidden" runat="server" id="hiddenChoice" />
<input type="button" id="launch" onclick="DoSomething()" />
....
In your code-behind:
VB Code:
'declerations section
Protected hiddenChoice As System.Web.UI.HtmlControls.HtmlInputHidden
Private Sub hiddenChoice_ServerChange (Sender As System.Object, e As System.EventArgs)
If hiddenChoice.Value = 1
'do some code
Else
'do some other code
End If
End Sub

Re: HOW to write Javascript in VB.NET?
You could also use an XMLHTTP request, but that is probably more involved than using a hidden input field.
