    I'm use tooltipmanager in RadListView follow by demos tooltip load on demand, But OnAjaxUpdate not working when mouseover item in radlistview 


    <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
            <telerik:AjaxSetting AjaxControlID="ListShowAccreditation">
                    <telerik:AjaxUpdatedControl ControlID="ListShowAccreditation" LoadingPanelID="RadAjaxLoadingPanel1">
                    <telerik:AjaxUpdatedControl ControlID="RadToolTipManager1"></telerik:AjaxUpdatedControl>
    <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server">
    <telerik:RadToolTipManager runat="server" ID="RadToolTipManager1" Position="Center"
        RelativeTo="Element" Width="400px" Height="200px" Animation="Resize" HideEvent="LeaveTargetAndToolTip"

                    Visible="true" />
                <asp:Label ID="lblComma" Text=", " ForeColor="#0083BA" runat="server" /></a>

    In codebehind

    private void UpdateToolTip(string elementID, UpdatePanel panel)
               Control ctrl = Page.LoadControl("AccreditationPopup.ascx");
               UCAccreditationPopup details = (UCAccreditationPopup)ctrl;
               details.ID = elementID;
           protected void OnAjaxUpdate(object sender, ToolTipUpdateEventArgs args)
               this.UpdateToolTip(args.Value, args.UpdatePanel);
           protected void ListBox_SelectedIndexChanged(object sender, EventArgs e)

    I'm newbie to use telerik.

    You need to add targets for the tooltip manager in order to have tooltips with load on demand on concrete elements. A similar example can be found in this demo: http://demos.telerik.com/aspnet-ajax/tooltip/examples/targetcontrolsandajax/defaultcs.aspx?product=tooltip. I am also attaching here a small sample that shows the logic with a listview control.

    Thank you,  

    I was wrong to  e.Item.FinControl("");  

    I can do it
    Control target = e.Item.FindControl("lblAccredit");
                RadToolTipManager1.TargetControls.Add(target.ClientID, (e.Item as RadListViewDataItem).DataItemIndex.ToString(), true);
