By design, when a RadWindow is closed, it is not destroyed but remains hidden -
this is done to provide the caching feature of the control. That is the reason why your page_load event is not fired when the window is re-opened.
When you need to
destroy the popup and open a fresh one, I suggest to set the DestroyOnClose
property to true. Note however that in this case, you will not be able to open
the same RadWindow again (e.g. with the user-defined height, width, etc.
properties). If you use DestroyOnClose, it is best to move all the user-defined
properties to the RadWindowManager and open the windows with radopen().
