问题
I have a radtooltipmanager that have their target control inside datalist. This datalist is bound on the server side using ajax. I set the target control from itemdatabound event of datalist, but tooltip doesn't work.
Any help please.

If you are using AJAX to initially bind the list (i.e., it does not happen on the initial load, but during a subsequent partial postback), make sure that you include the RadToolTipManager in the partial update, because otherwise its new targets will not travel to the client.
