Hi Kirk,

I am afraid, there is no way to stop the reloading. However, you can hook to the PaneStateChange event of the Docking control, which fires every time the state of the pane is changed - docked, floating, pin, unpin, etc.

Hope this info helps.

I did see the PaneStateChange event. The problem is this event is called after pane is unloaded. I really need to find a way to tell before the pane is unloaded that it is about to unload.

Hi Kirk,

Instead Unloaded event of the content of the Pane, I am afraid there is no other suitable event in this situation. There are also some preview events, which I am not sure that are going to work for you, like PreviewPin, PreviewClose, PreviewUnpin. You can check them out also.
