Scheduler sharepoint javascipt error b.TouchScrollExtender is null or not an object

[Ilias]

Hi,
we are using RadControls for ASP.NET AJAX Q3 2010 in SharePoint 2010 custom user controls.
In general, if I have a scheduler in a user control and after adding the scripts programmatically as posted here (asp-updatepanel-and-radscheduler-issues) it works fine with update panel and the default ajax script manager of sharepoint.
The problem starts when using a RadTabStrip that loads to the RadMultiPage user controls programmatically. When the user selects the tab that loads a user control that contains a scheduler control then a javascript error occurs ('b.TouchScrollExtender' is null or not an object).
If I don't include the RadTabStrip into an update panel then I can select another tab and navigate away from the tab with the scheduler control, but if I use update panel or even RadAjaxManager and AddAjaxSetting programmataically then I cannot navigate away and do any other action.

Thank you in advance,
Ilias

Hi Ilias,

Let me suggest you add the script references for RadScheduler and RadTabStrip through the ScriptManager  - as described in this help article.

Hi,
I followed your suggestion but with no luck.
I had already added in the OnPreRender event the scripts for the scheduler, except of the script "Telerik.Web.UI.Scheduler.ContextMenu.RadScheduler.ContextMenu.js" which is not included in "Telerik.Web.UI, Version=2010.3.1317.35" dll which I use in SharePoint.
So I added also the following

//scripts for tabstrip
scriptManager.Scripts.Add(new ScriptReference("Telerik.Web.UI.Common.Scrolling.ScrollingScripts.js", telerikAssembly));
scriptManager.Scripts.Add(new ScriptReference("Telerik.Web.UI.Common.Navigation.NavigationScripts.js", telerikAssembly));
scriptManager.Scripts.Add(new ScriptReference("Telerik.Web.UI.TabStrip.RadTabStripScripts.js", telerikAssembly));

//scripts for multipage
scriptManager.Scripts.Add(new ScriptReference("Telerik.Web.UI.TabStrip.MultiPage.RadMultiPageScripts.js", telerikAssembly));

but I didn't see any difference. The javascript error continues to occur.
Maybe any other suggestion?
Thanks,
Ilias

Hello Ilias,

Please try removing the Telerik.Web.UI.Scheduler.ContextMenu.RadScheduler.ContextMenu.js registration, and register the Telerik.Web.UI.Scheduler.ContextMenu.Plugin.js instead.

Kind regards,

Hi,
I added Telerik.Web.UI.Scheduler.ContextMenu.Plugin.js but it didn't change anything.
After a postback happens the RadAjaxLoadingPanel never stops to render.
I believe it has to do with the scheduler and the tabstrip control, because if I use only the scheduler in a page it doesn't produce this kind of error but it works fine.
Thanks,
Ilias

Hello Ilias,

When a control that loads scripts on the run is displayed via Ajax request in SharePoint – it does not load it’s scripts. The only way to overcome this SharePoint bug is to register the scripts manually.
As I see - you have tried doing this for the RadScheduler and the RadTabStrip.
So the only thing that I can suggest you is to simplify the scenario that implement and avoid loading the RadSheduler via user control.

Kind regards,
