In running your sample browser, I had thought I saw a ComboBox with a CheckBox to handle nulls. But then I thought you PartEditBox could do It. I defined a DropDownContentTemplate as a ListBox and that gives me a list. But what then? My drop down list box does not select anything. Is it possible to make PartEditBox a ComboBox? I thought I could write my own class inherit TypedSpecificEditBoxBase(of Integer) (My SelectedValue is an integer), but I not should what I would need to do.
If you could point my in the right direction. Or just tell be it can't be done.
