The html below shows DataList "DiscountLi st" nested within DataList
"EventItemList" . DiscountList contains a Label control.
I'm trying to find the label, using FindControl, during
EventList_ItemC reated (below the html), but it's always <undefined
value> (null). Everything else works fine. Eventually I need to set
the value of the label depending up the Count of the DataView
"dvDiscount ". For now I'll settle for just finding the damn thing!
Anyone got any ideas about this?
Thanks everyone.
