Create a cbo subclass (if you don't already have one) and add your property in the class designer. If you have existing cbos that you want to switch to using this new subclass...I find it easiest to use the scx's and convert the controls there. Does that sound like what you want to do?

>How do I add a property to a control in VFP3? I would like a combo box to have its own array (this.myarray) rather than associating the array with the form (thisform.myarray).
