WPF- MessageBox to be top most

Question

I have a WPF application, i need the MessageBox to always be top most. in win forms i would do something like that:

System.Windows.Forms.MessageBox.Show(new Form() { TopMost = true }, "sure you wanna save?", "confirm", MessageBoxButtons.YesNo)

but how do i do that in WPF?

i saw a few different answers but non of them work for me e.g:

MessageBox.Show(Application.Current.MainWindow, "Im always on top - of the main window");

My mainWindo is null. In my application the MessageBox is opening from different pages- not windows

Any idea how i do it in the most simple way?

Answer 1

Use MessageBoxOptions.DefaultDesktopOnly and it keeps the MessageBox on top of the window.

MessageBox.Show("You entered an incorrect value. Try once more.", "Wrong input", MessageBoxButton.OK, MessageBoxImage.Exclamation,MessageBoxResult.OK,MessageBoxOptions.DefaultDesktopOnly);

Answer 2

  this.Dispatcher.Invoke((Action)(() =>
{
 MessageBox.Show("Im always on top - of the main window");
}));

This will run it in the UI thread.Throw this in the method that shows the msg box.
