public static void ShowDialog(string message, Window owner)
{
// mask
Grid layer = new Grid() {
Background = new SolidColorBrush(Color.FromArgb(128, 0, 0, 0)) };
// parent form original content
UIElement original = owner.Content
as UIElement;
owner.Content = null;
// container Grid
Grid container = new Grid();
container.Children.Add (original); // put the original content
container.Children.Add (layer); // put a layer above the mask
// will be equipped with original content and mask containers assigned to the parent form
owner.Content = container;
// pop-up message box
MessageBox box = new MessageBox() {
Owner = owner };
box.tbc_message.Text = message;
box.ShowDialog();
}
The message box is closed
