Greetings - I host user control inside an update panel, this user control then contains sub user controls, I want to create something like a drop down load on demand tool tip using the following code.  It doesn't call the instances ajax update but i think the parent's.  How do I get this to work?

asp:UpdatePanel runat="server" UpdateMode="Conditional">


<telerik:RadToolTipManager runat="server" ID="MyRadToolTipManager1" Position="Center" RelativeTo="Element" Animation="Resize"

HideEvent="ManualClose" ShowEvent="OnMouseOver" ShowCallout="true"

RenderInPageRoot ="true"

Skin="Default" OnAjaxUpdate="OnMyRadToolTipManagerAjaxUpdate1" AutoTooltipify="false" >


<telerik:ToolTipTargetControl TargetControlID="MyLabel" Value="MyLabel" />



<asp:Label runat="server" ID="MyLabel" Text="Content" />

Hello Doug,

This markup calls the expected handler on my end.

Note that the OnAjaxUpdate handler will be called with each postback from the page, regardless of its origin (be it in the tooltip or not) to recreate the controls and this may be causing the confusion on you end.

Also note that only one RadToolTip can be visible on the page in any given moment. I am not sure what "dropdown load-on-demand tooltip" is, but if it includes nested tooltips you will not be able to have them both shown in the same time, showing the second will hide the first which will hide the second's target and thus the second will hide as well.
