Hi,
I have a RadListBox embedded into a RadDock. When the RadDock is opened (MyRadDock.Closed = false), I want to clear
the RadListBox.
At the moment, when the RadDock is closed and opened again, the ListBox still contains the items from the previous command call.
Unfortunately I don't find an event which is fired when the RadDock is opened. The client-side event "OnClientInitialize" is also called on PostBack but I want to preserve the ListBox content during a PostBack (which currently works fine) when the RadDock is opened.
Do you have any idea how I can clear the RadListBox every time the RadDock is opened but not on a PostBack?
Thanks!
