I dont know if this is possible as I cant seem to find a lot of documentation on the subject but the scenario is as follows.
I have a custom control that when dropped into a form gives all the controls on it a new property. This property is something akin to a help text field but there is a reason for reinventing the wheel :o)
Everything works fine and in design view any controls on the form have this property now but it is a text entry box. What I would REALLY like to do is replace that text entry box with a button style one that allows to me to display a custom form and capture the results of that. Something like when you define the columns in a listview.
Any thoughts appreciated.
