Question

So I have a user control within a window that creates a new dialog window when a button is clicked. I would like the window to appear on top of the window calling it. I tried to do this…

        NewDialog dlg = new NewDialog();
        dlg.WindowStartupLocation = WindowStartupLocation.CenterOwner;
        dlg.ShowDialog();

The problem is the owner doesn’t seem to be the calling window (maybe because a user control is making the call and not an actual window?). So I tried adding this…

        dlg.Owner = Application.Current.Windows[0];

Which mostly works, but it is not a generic solution as sometimes my new windows have to call a new window, and I want them centered on the calling window, not the primary window. Is there a better way to set the owner correctly to the window the user control it is a part of? I have tried many variations that all seem to have some quirk where the window comes up in a completely different place, or something doesn’t evaluate right and throws an error.

Any suggestions?

If this is not of type Window use static Window.GetWindow Method to get the host window.

dlg.Owner = Window.GetWindow(this);
