Capture Pane Close event

[Muhammad Irfan]

Hi, I am trying to use create dynamically Panes in RadDocking using PaneGroupExtensions class using MVVM pattern. It is working fine with my item source. However my requirements is slightly change that if any Pane is visible already then it should not add a new tab again, instead just highlight (select) previously added Pane.
For this I am holding a Dictionary that which Pane is visible but I can't find any way that when user close Pane from RadDocking then how can I capture this event so that I can remove the object from my dictionary.

Many Thanks,

Hi Muhammad,

You can use the Close event of the Docking, which is fired when a pane is closed.

Thank you Konstantina, But I could not see any way to capture this event using Binding with my ViewModel event. Can you please give me any code snippet of this event with proper binding (in MVVM pattern).

Hi Muhammad,

I can suggest you the following approaches:
1) Since you keep a dictionary of the Panes in the ViewModel, you can add some logic in the View, which will tell the ViewModel that a Pane has been closed and remove it from the dictionary.
2) You can bind to the IsHidden property of the Pane.
3) There is a third approach which is illustrated in this help resource:

However, I haven't try it with RadDocking control, so I cannot confirm that is working smoothly, but it is a good practice and it's worth the try.

Hope this information was helpful.
