VB

Private Sub frm_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
        If e.KeyCode = Keys.Delete Then MsgBox("You have pressed delete")

Please ensure that this.KeyPreview = true; is set correctly.

Also note that in WPF events are bubbled or tunneled. As a result, events are sometimes not handled where you expect them to be handled.
Go through To bubble or tunnel basic WPF events[^] for a better explanation.

Further, PreviewKeyDown is a tunneling event and is easier handled at the top of the visual tree i.e. window level.

Solution 1

There is e.Key property for KeyEventArgs in WPF

Console.WriteLine(e.Key.ToString());

Hope this helps!
