Active document window handle

[prakash.muthu]

Hi,

Looking for an API to get active window handle of current document in display. Trying to find the highlighted area view window handle.

Thank you.

using UIframework.dll (part of Revit installation) and 

using Xceed.Wpf.AvalonDock.dll (part of Revit installation) and 

using Microsoft.VisualStudio.Utilities nuget

you can get that via this code:

 var docControl = MainWindow.getMainWnd().FindDescendant<LayoutDocumentControl>();

Getting error on using above code.

'MainWindow' does not contain a definition for 'FindDescendant' and no accessible extension method 'FindDescendant' accepting a first argument of type 'MainWindow' could be found (are you missing a using directive or an assembly reference?)

Do i need to add more references?

Thank you Mustafa. Now able to get the control. Further how to get the window handle and mapping it with specific document.

you can get the handle using PresentationSource

var hwndSource = PresentationSource.FromVisual(docControl) as HwndSource;
var handle = hwndSource.Handle;
