cell.Attributes.Add(

"id", "Calendar1_" + i.ToString());

RadToolTipManager1.TargetControls.Add(e.Cell.Attributes[

"id"], i.ToString(), true);

This works on the current month view.  So I'll hover and tooltip shows.....But when I add a future Event, I'll click on the next month link and it will show..ex. 9/9/2011....but when I hover all I get is a regular tooltip.
         Things I want to do:
                  1.  I want to load all my events info as the Page/Calendar loads.  I do not want to make an Ajax call.
                  2.  Tooltip doesnt seem to work on Weekends either, even on the current month....ex. 08/20/2011.....Any ideas?
