AutoHide ToolWindow Expands Behind Direct3D

Docking/MDI for WPF Forum

Platform: .NET 4.5
Environment: Windows 10 (64-bit)

In my Docking/MDI application, if a document in the main workspace contains a Direct3D rendering area (which is actually contained in a WindowsFormsHost), and an AutoHide ToolWindow is expanded, it pops out *behind* the Direct3D.  It does appear properly when the ToolWindow is pinned, and when the main document is not Direct3D, AutoHide ToolWindows expand in front of the doc, as expected.

Hi Justin,

Yes that is the airspace issue that WPF has in general with interop content.  But the good news is we have workarounds that can be activated in Docking/MDI to handle this.  Please read through the "Interop Compatibility" topic in the documentation for details on how to activate them.
