If you would like to display a count (number of items selected), regardless of the number of items selected:
DropdownBar_ShowCountAfterNItemsSelected = 0
NothingSelectedText
0/x Selected
AllSelectedText
x/x Selected
x
ShowCountAfterNItemsSelected
AllSelectedText.
Implementation Note:This implementation may seem complicated, which it is, however it retains flexibility.For example, it retains the ability to use a separate messages when all items, or no items, are selected.
