c# capture Ctrl+PageUp keystroke

I am having trouble capturing Ctrl+PageUp keystroke in a ListView control in WinForms application.

I am using this code to capture keystrokes - 

private void ListViewEx_KeyDown(object sender, KeyEventArgs e)
{
...
if(e.Control){
if((e.KeyCode ^ Keys.Left) == 0)
    MessageBox.Show("Left"); //shows messagebox
else if((e.KeyCode ^ Keys.PageUp) == 0)
    MessageBox.Show("PageUp"); //does not
...
}

Do I need to dive into WndProc to process this key? Thanks.

Edit: I've found out that this works, the problem was in enclosing TabControl handling these keys before ListControl got to them.

The e.KeyData argument includes the modifier keys. Make it look like this:

  if (e.KeyData == (Keys.Control | Keys.PageDown)) {
    // Do your stuff
    Console.WriteLine("Ctrl+PgDn");
  }

No need for WndProc:

if ((e.Modifiers & ModifierKeys) == Keys.Control && e.KeyCode == Keys.PageUp)
{
    // ctrl + page up was pressed
}
