Yup...it don't work. So what I do in these situations is to set the ControlSource to a container property and create an Assign for that property. In the Assign I update the backend (real) ControlSource with a REPLACE.

>I can not the Value_assign method to work with a checkbox control. When I click on the checkbox the value of the checkbox toggles true and false visually, but the value_assign does not fire. I have put a breakpoint in there, no dice, not even SET STEP ON works. Any ideas why it isn't working? Can anyone reproduce this behaviour with VFP6 SP4?
