I am trying to create a GoGeneralNode with a GoCollapsibleHandle attached. The problem is that no matter what style I give this handle it only displays a circle (whether expanded or collapsed). Here is the code I use to add the handle which is located inside the ctor of my subclass of GoGeneralNode:
Yes, it does matter that your parent class implement IGoCollapsible. Is IGoCollapsible.Collapsible false for your node? If so, then GoCollapsibleHandle will draw a circle inside the handle.
That was it. Wow, that was a fast response! Thanks a lot.
