When user clicks on a tab, I want to update my ViewModel's ActiveWindow property. When I update my ViewModel's ActiveWindow property, I want that tab to be activated. But DockSite's ActiveWindow property is read-only. So what property of a DockSite do I databind to accomplish this?

Hi Jim,

I don't think there is a property you can set via binding, but you can call the window's Activate() method when you want to activate it programmatically.

I'm using MVVM so binding is important for keeping views and models in sync. Without a bindable ActiveWindow property in DocSite, I had to write an attached property and handle model > view sync (in which I do call Activate). To handle the other direction I guess I'll have to handle an event. Which event fires when ActiveWindow property changes?

Hi Jim,

The DockSite.WindowActivated event fires when the ActiveWindow property changes.

Thanks. The atttached property I wrote is working in both directions now.

Howver...making DockSite.ActiveWindow bindable will save your users 60 lines of code, though.

+1 to Jim's request; it would be nuch nicer if ActiveWindow were bindable...

Hi all,

In Docking/MDI vNext (still in development), we have added a DockingWindow.IsActive property that is bindable and is get/set.  You can set that to true to make the window become the ActiveWindow.  See this blog post for details:
