Not out of the box. I have heard there is some script you can place on the
form that does something, but it didn't seem like a very clean approach, so
I didn't keep the url.
You can use the PAge.RegisterStartupScript to hook into the onUnload event
(http://msdn.microsoft.com/workshop/author/dhtml/reference/events/onunload.a
sp), popup a window and fire whatever you want to in the popup window, then
close it...not the most elegant, but likely your only solution. There's
likely a tutorial on it somewhere, google should help
One way to achieve is to open a new window with asp.net page in javascript
unload event and run your asp.net code from that page and close that page
also after your code execution.
