Question

I am creating a new WPF window that I want to be parented to another existing app. I do this with the:

Winforms.Show ( IWin32Window owner )

all the time, but since this app is using a WPF Window, I am looking for a way to achieve the same thing.

Any ideas?

Answer 1

The above way is valid to do this from a WPF parent window to a WPF child window

Window wpfWindow = new Window(); 
wpfWindow.Owner = this; 

If you want to have a WPF windows with a Winform parent you need to use the WindowInteropHelper class.

WindowInteropHelper helper = new WindowInteropHelper(wpfWindow);
helper.Owner = winFormWindow.Handle.
