Question

How do you display a custom UserControl as a dialog in C#/WPF (.NET 3.5)?

Answer 1

Window window = new Window
            {
                Title = "My User Control Dialog",
                Content = new OpenDialog(),
                SizeToContent = SizeToContent.WidthAndHeight,
                ResizeMode = ResizeMode.NoResize
            };
            window.ShowDialog();

Has worked like a magic for me. Can it be made as a modal dialog?
