How do you display an html string in the tooltip?

[T F]

I have a web service which will return an html string to the tooltip panel.  The tooltip panel does not render html but simply displays the string.  How can I get the panel to render the html string?  
Thanks!

Tooltip panel does not render html, but simply displays the string...

Hi T F,

Once the response is received then we add it to the RadToolTip's content div with the following code:
div.innerHTML = response;

The following code:

[WebMethod]
   public String SbuDetailHtml(object context)
   {
       string value;
       string regular = "regular<br/>regular<H1>regular</H1>";
       string encoded = Server.HtmlEncode("encoded<br/>encoded<H1>encoded</H1>");
       return value = regular + encoded;
   }

will display:

regular
regular

regular

encoded<br/>encoded<H1>encoded</H1>

Hope this helps.

Hello Petio -
Can you send a sample of the client code?  Including waiting for response?  I simply have this right now.

function

 

 

ShowSBUToolTip(element) {

 

 

 

var tooltipManager = $find("mgr_gwpctGrid_ctGrid_RadToolTipManager1");

 

 

 

var sbuid = element.getAttribute("sbuid");

 

 

 

 

//If the user hovers the image before the page has loaded, there is no manager created

 

 

 

if (!tooltipManager) return;

 

 

 

//Find the tooltip for this element if it has been created

 

 

 

var tooltip = tooltipManager.getToolTipByElement(element);

 

 

 

//Create a tooltip if no tooltip exists for such element

 

 

 

if (!tooltip) {

 

tooltip = tooltipManager.createToolTip(element);

tooltip.set_value(sbuid);

 

}

 

 

//Let the tooltip's own show mechanism take over from here - execute the onmouseover just once

 

element.onmouseover =

 

null;

 

 

 

//show the tooltip

 

tooltip.show();

}

Thanks

Hi Petio  -
I believe this is the same sample that is posted online and available from the install.  What I'm looking for is the javascript function response from the web service.  You mentioned that "div.innerHTML = response".  Where does that get set in the javascript?  In other words, what the does the results javascript function look like?
Thanks
TF

Hi,

The method's name is _onWebServiceResponse. The code below is its definition:

<script type="text/javascript">
    Telerik.Web.UI.RadToolTipManager.prototype._onWebServiceResponse = function (sender, eventArgs)
            {

                //Render result sent by the webservice
                var html = eventArgs.get_data();

                //Set tooltip content
                var div = document.createElement("div");

                //Check and make sure there is a tooltip updated by the service
                if (this._currentServicedToolTip)
                {
                    this._currentServicedToolTip.set_contentElement(div);
                    div.innerHTML = html;
                }
                this.raiseEvent('requestEnd');
            }
    </script>

Hope this helps.
