Modal x Modeless Windows

[xaotix]

I have various windows in WPF in project.

They are working fine when I call them by modal:

.ShowWindow()

Now I want the user to be able to interact with the model.
So I switched to modeless:

.Show()

But after that, all the textboxes are frozen.

How I can achieve this?

I faced this issue before, and this worked with me:

 MyForm form= new MyForm();

 ElementHost.EnableModelessKeyboardInterop(form);
 IntPtr hwnd = NavisworksHelper.GetNavisworksMainWindowHandle();
 WindowInteropHelper helper = new WindowInteropHelper(form);
 helper.EnsureHandle();
 helper.Owner = hwnd;
 form.Show();

If it worked please accept as solution

Thx a lot.

Worked like a charm!

The only thing that I needed to find out was what your GetNavisworksMainWindowHandle do.

            ElementHost.EnableModelessKeyboardInterop(window);
            IntPtr hwnd = ((MainWindow)Autodesk.Navisworks.Api.Application.Gui.MainWindow).Handle;
            WindowInteropHelper helper = new WindowInteropHelper(window);
            helper.EnsureHandle();
            helper.Owner = hwnd;
            window.Show();
