I have a RadToolTipManager setup like this:

<telerik:RadToolTipManager
    runat="server"
    ID="ttChart"
    Position="BottomCenter"
    OffsetY="-10"
    RenderMode="Lightweight"
    EnableRoundedCorners="False"
    RelativeTo="Element"
    Width="435"
    Height="350"
    HideEvent="ManualClose"
    HideDelay="800" 
    ContentScrolling="Y"
    Skin="Default"="3450
    ShowDelay="0" 
    Modal="True"
    ShowEvent="OnClick"
    Animation="resize"
    OnAjaxUpdate="updateChart"
    RenderInPageRoot="true">
</telerik:RadToolTipManager>

In my RadGrid I insert Cells with dymanic tooltip references - using OnAjaxLoad to load an ASCX.  Works great.

Problem is that the Loading image does not show - unless I remove ContentScrolling="Y", or Height="350".  Either of those seem to make the loading image come back when removed.  

Trouble is I would like to use both of these features.  Is this a bug?  (Using 2014.3.1209.45)

Hi Dan,

Indeed, this is a bug in the Lightweight RenderMode of the tooltip manager and I am logging it for fixing: FIX Loading sign is not visible when height or explicit scrolling is set in a RadToolTipManager with RenderMode=Lightweight. I hope the workaround I have provided will be suitable for you:

div.RadToolTip div.rtContent
{
    background-color: transparent;
}

I have also updated your Telerik points for your report.

Of course, you can, alternatively, fall back to the Classic RenderMode.
