Hi Sylvain ---

FYI --- Sometimes Assign on Value properties just don't fire period. It's a bug. As to your problem, can't you just make the property hidden in the class?

>I've created a control that I can drop on my form. In my control, there is a property that have an Assign() method. If I assign a new value programatically, the Assign() method fire. But if I assign a value in the property sheet, the Assign() doesn't fire.
