Passing KeyEvents to other classes

[Uchiha Jax]

I'm trying to get a KeyEvent in a DateTimePicker to trigger, the problem is
that it's within a different control and the parent control intercepts the
call.
I'm trying to work with a DateGridDateTimePickerColumnStyle that I picked
off off a post on a forum, the class wasn't complete as the picker in the
grid doesn't respond to keyboard input.

Therefore I wrote this to put in the ColumnStyle rather than a standard
DateTimePicker so I could pass the event from the ColumnStyle to the picker:

public class DataGridPicker:DateTimePicker
{
private KeyEventHandler keyEvent;
public DataGridPicker()
{
keyEvent = new KeyEventHandler(InternalCallKeyUp);
}

public void CallKeyUp(object sender,KeyEventArgs e)
{
this.Invoke(keyEvent, new object[]{this,e});
}
private void InternalCallKeyUp(object sender,KeyEventArgs e)
{
this.OnKeyUp(e);
}
}

I wrote it like this because my intial direct call (when the internal
version was public at first) locked up the program which I figured this was
the standard threading problem you can get when trying to call control
methods from a different thread.
However i'm still left with the same problem, the application hangs and I
get no feedback about the problem.

I guess i'm doing this the wrong way, could someone point me in the right
direction?
