Hi,

How to make pop up window from code behine without using
java script. And another thing is that, how to pass value
from the pop up window to a form if there is a textbox in

Making popup windows is a client task and as such it can be done only with
client tools. The only way to create a popup is javascript showModalDialog
call.

You can pass a value back from popup in window.returnValue property. The
javascript showModalDialog statement that started the popup will get this
value as a result of the call.
