I wanted to be able to control most of the aspects of the Collection Editor. First, I will admit, most of the ideas presented here came from various posts and examples found scouring the web. At this point, I don't remember where each idea came from, so if any of them are yours, let me know and I'll add credit in this post. Anyway, I will simply post the CustomerCollectionEditor. Comments explain most of what it is doing. If you need more clarification, just send me a note. I got help on setting the Font of the various items within the CustomCollectionEditor from the Forum Moderator John H. I also got help re-sizing the "listbox" from another Forum's user Reza Aghaei. Below is the code and an image of the customizations.
