I am looking for a server-side equivalent of the client-side function IsPinned().  I am setting my windows to be invisible each time a page is posted back; however, if they have been pinned then I want to keep them visible.

Hi Ed,

There is no such server-side property or event on the server - just like the standard popup, RadWindow is created and handled on the client only.
What I would suggest is to use the OnClientCommand event handler and if the command is "Pin" - to raise a flag (in a hidden field for example). Then you can check the value of that field on the next postback.

Thanks Georgi -- that nearly worked ... I now get the windows reappearing on a post-back but they are unpinned again, which means on the next post-back I lose them ...

What is the recommended way to keep windows alive during a post-back?

Hi Ed,

I am not quite sure how exactly you built the logic that you currently use, but generally speaking if you want the window to be explicitly pinned when you show it, you can set its InitialBehaviors to Pin.
e.g.
RadWindow1.InitialBehaviors = WindowBehaviors.Pin;

I hope this helps. If you still experience problems, please open a support ticket and send me a sample project that I can examine more closely.
