Here are two suggestions. Use the ItemDataBound event to set a property of a
control (probably the Text property of a Label in your case). You can do
this using either e.Item.ItemIndex or create a global integer variable and
increment it by 1 each time the ItemDataBound event is called (I recommend
using e.Item.ItemIndex because it is less code). Keep in mind that
e.Item.ItemIndex is 0 based, so depending on what you want you may want to
use e.Item.ItemIndex+1. If you have any questions, just ask. Good Luck!
