<p>I've tried to override WndProc, but no message show up on paste event.</p>

<p>Then I tried to create custom filter and using method PreFilterMessage I was able to catch message with value 257 (KEYUP event), but that's not enough...</p>

Use:
```
```
protected override void OnKeyDown(KeyEventArgs e)
 {
      if (e.KeyCode == Keys.V && e.Modifiers == Keys.Control)
      {
            MessageBox.Show("Hello world");
      }
      base.OnKeyDown(e);
  }
```
```
Make sure your form KeyPreview = true.
