'this._pickers.startDate' is null or not an object

[Ben]

VS 2010 (.NET 40) RadControls AJAX 2010 Q1

I'm using the most simple of setups...  SQLDataSource  and a table with only the columns suggested in the Scheduler's Data Source Configuration Wizard.  If i double click on any appointment that isn't an All Day event, i'll get this script error message.

Error: 'this._pickers.startDate' is null or not an object

which, when viewed in the debugger, refers to this line of code (line 4779) of the Telerik.Web.UI.WebResource:

 

var k=[$get(this._pickers.startDate.get_element().id+"_wrapper"),$get(this._pickers.startTime.get_element().id+"_wrapper"),$get(this._pickers.startTime.get_element().id+"_timeView_wrapper"),$get(this._pickers.endDate.get_element().id+"_wrapper"),$get(this._pickers.endTime.get_element().id+"_wrapper"),$get(this._pickers.endTime.get_element().id+"_timeView_wrapper"),$get(this._templateId+"_SharedCalendar")];

I have no other customizations to the RadScheduler: 

<telerik:RadScheduler ID="RadScheduler1" runat="server" DataEndField="EndDate"
DataKeyField="CalId" DataSourceID="SqlDataSource1" DataStartField="StartDate"
DataSubjectField="Subject" DataDescriptionField="Description"
DataRecurrenceField="RecurDesc" DataRecurrenceParentKeyField="RecurrenceID" >
</telerik:RadScheduler>

And i have one of these that comes before the RadScheduler declaration:

 

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" Runat="Server">
<telerik:RadScriptManager ID="RadScriptManager1" runat="server">
</telerik:RadScriptManager>

Any ideas?

Still getting this error. When I debug the application I don't get the error. However, if I navigate to the site just using the browser I get the error? I'm developing this on my local machine and I have a website pointing to this application so I don't need to debug to view the site.

UPDATE:
This appears to be an issue with the 3.5 dll. I upgraded my project to 4.0 and used the 4.0 dll and things started working.

Thanks for the update. We will log the issue and do some more investigation.

                    <telerik:AjaxUpdatedControl ControlID="RadScheduler2" LoadingPanelID="RadAjaxLoadingPanel1" />

                </UpdatedControls>

            </telerik:AjaxSetting>

        </AjaxSettings>

    </telerik:RadAjaxManager>

    <telerik:RadAjaxLoadingPanel runat="server" ID="RadAjaxLoadingPanel1" Skin="Office2007" />

 

    <asp:EntityDataSource ID="EntityDataSource1" runat="server"

Hello Sophal,

Can you reproduce the problem with the EntityDataSource demo at your local installation of the Telerik controls? If yes, please, let us know what modifications you have made.

Kind regards,
