Thanks Colin ---- Yeah, I'd like to see that list of properties if Doug has it. I mean, the workaround wasn't terribly difficult, it was a case, though, where I thought implementing the _Assign within the control and attached to a change in Value was good OOP.

Perhaps if Doug comes across this thread he could shed some extra light on this. Good Luck.

>>I have a checkbox on a form. The checkbox is from a class where I have defined a value_assign method. There is no controlsource to this checkbox. In Value_Assign, in the control instance on a form, I put code to turn or/off certain buttons depending on the state of the value (T/F). No dice. Doesn't work. No error -- just nothing happens. What *will* work is if I bind the control (controlsource) to a form property and put an _Assign on that form property.
