Detect Enter Key C#

Question

I have the following code which does not show the MessageBox when enter/return is pressed.

For any other key(i.e. letters/numbers) the MessageBox shows False.

Answer 1

private void textBox_PreviewKeyDown(object sender, KeyEventArgs e)
 {
            if (e.Key == Key.Enter)
            {
                MessageBox.Show("Enter key pressed");
            }
            else if (e.Key == Key.Space)
            {
                MessageBox.Show("Space key pressed");
            }
}

Use PreviewKeyDown event to detect any key before shown in textbox or input
