Telerik.Web.UI.RadToolTipController is null or not an object

[oneshot]

Hi,

I am trying to use the RadToolTip with the RadScheduler to show tool tips when hovering over the appointments.

I have copied this section of code from mutiple different articles and documentation files/examples

<script type="text/javascript">
  //<![CDATA[
           function hideActiveToolTip()
           {
             var controller = Telerik.Web.UI.RadToolTipController.getInstance();
             var tooltip = controller.get_ActiveToolTip();
             if (tooltip)
             {
               tooltip.hide();
             }
           }

           Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(beginRequestHandler);
           function beginRequestHandler(sender, args)
           {
             var prm = Sys.WebForms.PageRequestManager.getInstance();
             if (args.get_postBackElement().id.indexOf('RadScheduler1') != -1)
             {
               hideActiveToolTip();
             }
           }
  //]]>
</script>

but when i launch my page i get a javascript error saying 

Microsoft JScript runtime error: 'Telerik.Web.UI.RadToolTipController' is null or not an object

As of yet i have no idea whether it's something i'm missing or a problem with the build i'm using (Version Q3 2007 released 12/18/2007 taken from live example page).

I know this isn't the latest release but we have had to make a decision to continue development until a problem with the build stops us or the final production version is released.

Any help greatly appreciated

Thanks in advance

Hello,

I assume that you have used the RadToolTip integration example as a reference. The error message suggest that you have not included a RadToolTipManager instance on the page. Here is how the definition looks in the example:

<telerik:RadToolTipManager runat="server" ID="RadToolTipManager1" Width="300" Height="150"
Skin="WebBlue" Animation="None" Position="BottomRight" Sticky="true" Text="Loading..."
OnAjaxUpdate="RadToolTipManager1_AjaxUpdate" />

Hi Tsvetomir 

That is correct, the i have used the RadToolTip integration example and do have a RadToolTipManager on the page declared as shown i think the only difference between yours and mine is i removed the Skin="WebBlue" attribute

<telerik:RadToolTipManager runat="server" ID="RadToolTipManager1" Width="300" Height="150"
  Animation="None" Position="BottomRight" Sticky="true" Text="Loading..." OnAjaxUpdate="RadToolTipManager1_AjaxUpdate" />

I have put in a temporary work around as follows

 

 function hideActiveToolTip()
            {
                if(Telerik.Web.UI.RadToolTipController != null)
                {
                    var controller = Telerik.Web.UI.RadToolTipController.getInstance();
                    var tooltip = controller.get_ActiveToolTip();
                    if (tooltip)
                    {
                        tooltip.hide();
                    }
                }
            }

but i have a feeling that i shouldn't need to do this according to the documentation.

Thanks

Just as an update, i now receive a popup tooltip as soon as i enter the scheduler! it's as if the RadScheduler has been added as a TargetControl of the RadTooltipManager but this is not the case. 

due to this when the RadToolTipManager1_AjaxUpdate event fires the split on the first line fails as the TargetControlID is RadScheduler1 (there are no underscores), this causes and index out of bounds error.

Can anybody help with this issue as i feel if i can solve this one i wont have to worry about my inital problem as the javascript "tweak" should cover it

Thanks in advance

Do you have any TargetControl for it or no?

[oneshot]

Hi Piyush,

At the point in time where the popup is occuring on the RadScheduler control i do not have any targetcontrols registered with the RadToolTipManager.

When i do have TargetControls registered with the RadToolTipManager i get an error just after the RadScheduler1_AppointmentCreated event has fired, this states 

Microsoft JScript runtime error: Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method.

and occurs in the javascript in a ScriptResouce.axd file, the line where it breaks is

if ((typeof(element._events) !== 'object') || (element._events == null)) throw Error.invalidOperation(Sys.Res.eventHandlerInvalid);

where this javascript is being called from i'm not sure but have a feeling it is the line in the javascript function above that reads

Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(beginRequestHandler);

Again i am not certain on that one but figured it may help.

Thanks in advance!

Hello,

Please, make sure that you are using the latest version of the Prometheus suite. We fixed a similar problem in Service Pack 2 and using an older version my be the cause of your problems.

I've had the exact same problem and I've tried all possible solutions.
What worked for me was to add a lot of stuff into my web.config file and deleting the following line which was cuasing the error.

<

xhtmlConformance mode="Legacy"/>

I'm not sure what it does but after tracing a lot of hours, this was cuasing the problem for me.

my config looks like this now:
