ASP .NET Confirm button

Question

Hi folks,

 

I am quite  new to Web application development. I need to display a popup (confirmation) message in asp .net application.

 

on event of button click in my application vbscript function is called to execute certain functions.

 

Actual requirement is :

 

..

 

  functions are executed removed for brevity..

..

 

if(confirm(popupmsg) == "cancel") // Show a popup message& if response is cancel then return from c# code.

  {

       return; // I should return  

   } 

  

Any help appreciated.

 

Thanks,
