In the KeyDown event, check to see if the key is PageDown. If it is,
then set the Handled property of the KeyEventArgs to true. At least
that's the simplest way I can think of
Private Sub SomeComboBox_KeyDown(ByVal sender As Object, ByVal e As
System.Windows.Forms.KeyEventArgs) Handles SomeComboBox.KeyDown
If e.KeyCode = Keys.PageDown Then
e.Handled = True
End If
End Sub
