Hello: 

I have a Gridview with a ToolTip in an ItemTemplate Column Type, loading information
through an  user control. At the top I have a DropDownList that filters the information
displayed when loading the page. The problem occurs when, in the first load of the page and,
according to the DropDownList filter value, there is no results; when I change
the filter value, and data is displayed in the gridview, the OnAjaxUpdate event does
not fire, which does not happen if i got results in the first page loading, so I think that
there is some kind of detail I'm forgetting, on the ItemDataBound event.
Any suggestions?
  
Thanks.

Hi,

I advise that you examine the following demo that is quite close to this case: http://demos.telerik.com/aspnet-ajax/tooltip/examples/targetcontrolsandajax/defaultcs.aspx?product=tooltip. You need to make sure that targets are added when needed and that they are deleted before the grid is paged/filtered. Also, the RadToolTipmanager must also be a part of the partial postback.
