C# WPF - Parent window jumps to top left corner of screen when Child window is shown

Question

How do I stop this from happening? My parent window just jumps to the top left part of the screen when ShowDialog() is called.

TransparentWindow trans = new TransparentWindow();
        trans.ShowDialog();
        trans.Dispose();

Thanks!

I think your window must be transparent to show up the parent window. If you call ShowDialog, it should go above the parent. You might also try for TopMost feature.

Are you calling the ShowDialog from the Parentwindow? I have been using this several times with WPF, and it works great to me.
