    RadToolTipManager response error:
     Exception=Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 0

    And telerik dll version is 2010.1.309.35. Please help me..

            function ShowToolTip(sender)

                   //If the user hovers the image before the page has loaded, there is no manager created
                   if (!tooltipManager) return;

                   setTimeout("", 3000);
                  //Find the tooltip for this element if it has been created
                  var tooltip = tooltipManager.getToolTipByElement(sender);
                  //Create a tooltip if no tooltip exists for such element
                  if (!tooltip)
                      tooltip = tooltipManager.createToolTip(sender);

    Please change the "onclick" event to  "onmousedown" event

    cell.Attributes.Add("onmousedown", "ShowToolTip(this);");  (Working Code)
    //cell.Attributes.Add("onclick", "ShowToolTip(this);"); (Previous code)

    Hello Sunil,

    I examined your code and what I noticed is that you have AutoPostBack = true for the calendar and at the same time you have set OnClick to be the ShowEvent for the RadToolTip. Please, note that this configuration is invalid because what actually happens is that since the tooltip should show onclick it cancels the postback because otherwise there is a logical problem. If you perform a postback onclick this means that the tooltip will not show because the page will be submitted. This being said what I can suggest is to cancel the postback on click and if a postback is needed on some condition after the tooltip is shown to invoke it through the client by using the built-in __doPostBack function.

    All the best,
    the Telerik team
