I have a treeview control on a form created with MM version 5 that works beautifully. Realizing later that I needed the same control on more than one form, I created a custom TreeView control (now in MM version 6.2), added the same code to the AddNodeHook, PostAddImageListHook, and all of the other methods and properties as the working version.

After dropping the control on a form, it trys to load, but returns the following messages:

"You must implement MFRSetTreeViewProperties method by entering code in the subclass".

It repeats this for MFRClearAllNodes, MFRSetNodeExpandedImage, MFRBuildNodeKey and finally crashes. None of these methods are utilized in the working control and the Dev Guide doesn't really go into much detail about this. Is this a newer control that requires diffent coding or am I missing something? BTW what does the MFR prefix stand for?
