在多个 WPF 控件中托管相同的 Win32 window

Question

I want to show the same Win32 window within different WPF user controls at the same time, is this possible?

I have an application with a main WPF Window with multiple child user controls. I modify the visibility of these user controls so only one of them is visible at a given moment. Two of these user controls contain a binding with the control that hosts a Win32 window (inherited from HwndHost), but when running the application I only see the Win32 window when visualizing the first of these user controls. Am I missing something?

Answer 1

A window in Win32 can't be displayed in two different places.
