WPF SizeChanged event doesn't fire

Question

This is a bit of a noob question.

Basically, I have a grid MainGrid in my WPF window

I'd simply like to be notified when the MainGrid is resized ( when user maximizes/resizes the window).

This does nothing at the moment. Am I supposed to declare and then add this SizeChanged event earlier before it will work?

private void MainGrid_SizeChanged(object sender, SizeChangedEventArgs e)
        {
            MyTextBox.Text = "MainGrid resized";
        }

Thank you

If you have your event in code-behind and this in XAML:

<Grid SizeChanged="MainGrid_SizeChanged">

it will work.
