overriding controller event

[alexia.bee@gmail.com]

Hi All,

I've created a crontroller which has 3 text boxes. I set for all text
boxes in this cotroller a key_press event.
In my other app which uses this controller, I want to override the
key_press event of the first text boxes in the controller.

Is there a way to override an event of controller or the first text
box of the 3?

Thanks,
Alexia.
