Hi,

I am in the process of writing a custom control. In the OnMouseDown
method I call this.Focus() to enable the control to receive keystrokes
in OnKeyDown(). My control is hosted in a MDI form.

Originally my control inherited from UserControl, but then the call to
this.Focus() returned false and no keypresses were received. The I
changed it to inherit from Control and everything works as expected.

Why doesn't it work when I inherit from UserControl?

thanks,
Michael

UserControl is a container Control, which is designed to host other Controls
in a composite form.

So it is in this case correct to inherit from control - the reason for
inheriting from a usercontrol is simply that is what I was given by a
wizard I ran, so I never gave it mouch thought until I ran into
problems ;-)

Thanks for the answer.
Michael
