This code is my "Cancel Page" confirmation.
If I pick "Yes" (to Cancel), my code behind (button) code runs, and
redirects me.
If I pick "No", I stay on the page.

Hi all:
I have an ASP.NET form that submits info to the server, but the customer
wants a confirmation window to open when the user clicks "Submit", and
then the user would have to click "OK" on the popup window to have the
main form submit. I found some samples of using JavaScript to create a
popup window, but then the OnClick event for the form button runs the
JavaScript as opposed to the server side code.
Can anyone suggest how I can accomplish this?
Thanks.
John.
