Hello Dipti,

I have already answered you in your other forum post. For convenience I am pasting my reply below:

I am not sure what exactly you want to achieve - what do you mean by minimizing in a treeview? As for persisting the state of the RadWindows in postbacks, with the current version of the control, this is theoretically possible, however the implementation will be very complex and I cannot guarantee that it would work in all scenarios.
The good news however is that providing such feature for RadWindow for ASP.NET AJAX is in our ToDo list for one of the following releases.

I have a project here that gets you along the correct path, I think. Using the 'PreserveClientState' the window will reload into the correct state.

Two issues I have found (and did not have time to investigate further):

1. If you do not specify the content to be loaded directly in the window, it will reload to a blank window. You have to either set the NavigateUrl in the window or do it in your reload method somewhere.

2. The isMaximized() and isMinimized() methods both return false on the page reloading. This presumes that the 'state' is not defined in the object when you minimize or maximize it. It is recalled from ViewState, but it is not explicitly set in the Window. A bug? Or maybe I am not seeing how to extract it?

Anyway, I have two buttons, one opens the window, the other executes a postback. The window reloads and then resizes to the last known state.

Thanks for listening.
