Why is my addhandler not firing?
In the Sub “CreateTagStyle”, the AddHandler is not firing when the LinkButton is clicked. Is there some reason that addhandlers can’t be added at certain points of the page lifecycle?

ItemDataBounddoesn’t run on postback, so your events won’t get rewired if a postback occurs. You should be usingItemCreatedinstead:Event sequence
