Solution 1

How about using the KeyDown event.

First set KeyPreview to true. Do it in constructor.

C#

this.KeyPreview = true;
this.KeyDown += new KeyEventHandler(KeyDownEvent);


void KeyDownEvent(object sender, KeyEventArgs e)
{
    if (e.Control && e.KeyCode == Keys.X)
    {
        this.Close();
    }
}

It should work now.

There is a problem here: it works only for a control having focus. OP needs a shortcut which should work everywhere. My 4.

I think it will close the window even if the focus is on some other control. Or am I missing something?

Ah... because of key preview..?
Probably I missed something. There was something which is not quite clear for me about it, I need to check up...
I'll re-vote by 5, thanks for your note.
