I have a datasheet form with a datasheet sub-form. When the user clicks on the + on the main datasheet form, the sub-datasheet form appears as it should. If (s)he then clicks somewhere on the main datasheet form, I want to make the subform go away (programatically change the + to a - and render the subform inactive). Is there a simply way to do this? I'm not sure how to refer to the + and - button. I'd be happy if I could just close the subform but I don't know how to do that from the main form either. From everything I've seen on the internet, it doesn't look like it's possible.
