For client-side user interaction, use JavaScript.
 
for example:
create a button: button1
Page_Load():
this.Button1.Attributes.Add("onclick","javascript:if(confirm('No to
cancel?')== false) return false;");

if "Cancel" button pressed, this page will not post back.
 
Just to add to this.

You can ONLY cancel the post back with javascript like this, you cannot
branch and "do other things".

Just a note: don't change the javascript to the seemingly identical but shorter
return confirm('No to cancel?')
because .Net can add it's own javascript to that onclick handler. This shorter
version would prevent the execution of that code! This is also why you *need*
the closing ";" to separate your code from the additional code.

By the way, you don't need to specify "javascript:" for an onclick handler.
