>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?

Hi Evan,

Value_Assign will fire if you add

this.value = this.value

into checkbox.InteractiveChange event.
