How to Find active Tab in Tabbed MDI - Docking/MDI for WPF Forum

Posted 16 years ago by United Biosource - United Biosource

Version: 4.5.0486

I want my Tabbed MDI page to register command bindings to the common windows commands (Save, Edit, etc.) and then call a command on a control in an MDI Container as appropriate, but I don't see how to get a reference to the Active window within the MdiContainer. MainDockSite.ActiveWindow doesn't restrict possible windows to only those in the MDI container. How can I do this?

Thanks.

Found it, I think:

var window = MyMdiContainer.SelectedWindow.Content;

or just

var window = MyMdiContainer.SelectedWindow;

if you only wanted the tab window rather than the control inside it

Sydney,

Never track container instances since they are transient and are created/destroyed at run-time as needed.

Instead use DockSite.LastActiveDocument. That should give what you wanted.

Will this work even if

a) a user has clicked on one of the Toolbars in the DockSite that is not in the Workspace
b) I don't have any Documents in my workspace, just tool windows

Yes it should. The term "document" means any document window or tool window in the MDI area.
