<script type="text/javascript"><br>
    var currentTooltip = null;<br>
<br>
<br>
    function OnClientBeforeShow(sender, args) {<br>
        //Hide the currently visible tooltip <br>
        if (currentTooltip) {<br>
            if (currentTooltip != sender) currentTooltip.hide();<br>
            return;<br>
        }<br>

<br>
    function centerTooltip(img) {<br>
        if (currentTooltip) {<br>
            currentTooltip.set_contentElement(img);<br>
<br>
<br>
            //use the method updateLocation because it does not call WebService's method which loads the content <br>
            currentTooltip.updateLocation();<br>
            currentTooltip = null;<br>
        }<br>

Bad example, poor support and waste of money :(

Hello Vladimir,

The issue here is that after you set the URL you need to pass it to an object that is going to be displayed in the tooltip. I am attaching a simple page based on your initial code that illustrates how to populate the tooltips of RadToolTipManager. You can extend the logic to show a more customized content.

The main difference between RadToolTipManager and RadToolTip is that RadToolTipManager utilizes LoadOnDemand through AJAX or WebService which need to be configured, while RadToolTip has its content set straighforward in the declaration. More on the difference can be found in this Online Demo. 

Regarding to the quality of the support services, we are deeply sorry that you feel this way, but please note that the forums are a community resource and although we monitor them closely, we do not guarantee a timely reply here. The best way to reach our support staff is via the support ticketing system - the support system assigns a response time for all of your questions, depending on your license and ensures that all questions will reach the respective developers, if needed. In addition, you will be able to review your support history at your leisure. In this way your issues will be managed more precisely.
 

All the best,
