I am trying to do something pretty simple - but can't see how it can
be done in ASP.NET.
I have an aspx web page with a form which opens up a new window. The
web page uses code behind to build the new window. There is simple
validation on the form.
However, after the form page validates and opens the new window, I
want it to redirect to another page (or stop displaying the form).
I've tried adding code to the aspx.vb page to handle this, but it only
affects the new window, not the window with the form on. If I try and
do the redirection before IsPostBack, then it always redirects.
I've tried adding code to the forms OnSubmit javascript event in the
aspx page, but then it interferes with validation - and bypasses it.
Here is an example of what I'm trying to do:
####### aspx page
<%@ Page Language="vb" Src="NGExample. aspx.vb" Inherits="NGExa mple"%>
<html lang="en">
<body>

The problem is that your CodeBehind is being run in the instance of your
class that runs in the new window. You need to use
Page.RegisterSt artupScript() to generate a JavaScript that uses the
window.open() method to open the new window, and then redirects to the URL
you specify.

Dear Nazir;
One solusion is to use HTML Control instead of Server Control and use both
