Hi Sylvian,

>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.

I read the rest of the thread so: Add the property at runtime (AddProperty()) and say that it isn't available from the property sheet.
