Subclassed Controls and Key Events

I have a subclassed control that needs to react to key down event. I have reimplemented the keyDown event on the control class and added the necessary code.

When running thin client, all keys down events are transmitted even if I have used registerFormKeys method on the form listing the codes of the keys I am interested in. The registerFormKeys method doesn't appear to work on the keyDown event if it has been reimplemented on the control classes.

I could remove the key down methods on the controls and on each form the control is added to add an event handler calling methods on the control class, but would rather handle all the events within the control class.

Does anyone know if you can restrict what keys are sent for a control rather than just a form, or even give me a definitive answer that it is not possible?

Hi Torrie,
Sorry I can't help, but we do what you are trying to do with a lot
of our subclassed control classes (and we have > 800 of them).

Does it behave the same in thin client as it does in fat client?
Have you implemented the keyDown event on the form? Do you make sure that reimplemented method does an "inheritMethod(...)"?
