I wanted to derive the enumEditBox for use in the propertyGrid. I added a couple shortcut keys and a .GotFocus and an ErrorTemplate. Now selection doesn't work with the mouse, short-cuts are nice though. still works if i type. I did put a hack in to keep it working in the meantime (see previewMousedown).
If I change the PropGrid:EnumEditorEx to the normal actipro:EnumEditBox (and change the style reference it all works just fine)
