I have an ASP.net application. The server side code is in C#. There is a button on the form. When that button is clicked, then a server side code should be executed and then the page should close.

When I write the code to close the page in .aspx file (by handing OnClick event) then the page closes even before the server side code can run.

I want that the server side code (for the button click handler) should first finish and then the page should close.

How to do that? Is there any way I can write code on server sid (in C#) to close the form?
