WindowsOpening and WindowsOpened events on DockSite do not take effect.

Docking/MDI for WPF Forum

I subscribe to the event on DockSite directly by the following code.

this.Content.dockSite.WindowsOpening += this.DockSite_WindowsOpening;
this.Content.dockSite.WindowsOpened += this.DockSite_WindowsOpened;
this.Content.dockSite.WindowsClosed += this.DockSite_WindowsClosed;
this.Content.dockSite.WindowsClosing += this.DockSite_WindowsClosing;

Then I create a ToolWindow and call the Open method to open it:

var window = new ToolWindow(this.Content.dockSite);

At this time, the Open-related events are not triggered, but the Close-related events are triggered when the ToolWindow is closed.

What could be the reason for this please? Our scene is not using MVVM way.

I opened our main demo and added the lines where you create and open the ToolWindow to a menu item event handler.  When I execute those, I see the WindowsOpening and WindowsOpened events firing in the Output tool window. 

It seems to be working fine here and nothing has changed in this area in a long time.  If you still think there is a problem, please reproduce it in a new simple sample project and send that to our support address so that we can debug the scenario.  Be sure to exclude the bin/obj folders from the .zip you send so it doesn't get spam blocked.  Thanks!
