KeyDown event not firing with .NET WinForms?

Question

I already have KeyPreview set to true in the form properties

I\'m working on a small program, and I\'m having a problem where it seems

Answer 1

Some controls intercept the arrow keys in the keydown event, but not in the keyup event. One solution is to derive the control class and override ProcessCmdKey:

Protected Overrides Function ProcessCmdKey(ByRef msg As Message, ByVal keydata As Keys) As Boolean

If keydata = Keys.Right Or keydata = Keys.Left Or keydata = Keys.Up Or keydata = Keys.Down Then
  OnKeyDown(New KeyEventArgs(keydata))
  ProcessCmdKey = True
Else
  ProcessCmdKey = MyBase.ProcessCmdKey(msg, keydata)
  End If
End Function
