    i have a group that is grouped alphabetically the problem is that for example i don't have any items beginning with 'a' but a is on the GroupItemSelector and when i tap it an exception gets thrown. 
    How do i disable 'a' or any other alphabets if my List doesn't contain Item.Substring(0,1) = 'the alphabet"?
    below is a pic shows that all the keys are enabled:
