First off, I'm a newb to the Telerik ASP.NET controls and am currently eval'ing the latest download. I've been through all of the forums and can't find an answer to this one.

I'm getting a "Microsoft JScript runtime error: Telerik.Web.UI.RadScheduler is null or not an object' error. I'm basing my code from what I found out on the "Scheduler / Binding to Generic List" demo. I'm using Master pages and am trying to simply bind the RadScheduler to a custom appointment class which I have created. I'm wanting to have read-only calendar representation of a single day's activities on a webform. Pretty basic requirement for now <grin>... My code below:

Markup:

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">

<telerik:RadScheduler ID="RadScheduler1" runat="server" EnableEmbeddedSkins="false"

Skin="MPower" ReadOnly="true" DataKeyField="AppointmentID" DataSubjectField="Subject"

DataStartField="Start" DataEndField="End" DataRecurrenceField="RecurrenceRule"

DataRecurrenceParentKeyField="RecurrenceParentID" width="750px"

DayStartTime="08:00:00" DayEndTime="20:00:00" TimeZoneOffset="03:00:00" >

</telerik:RadScheduler>

</asp:Content>

CodeBehind (located in the Page_Load):

AppointmentCollection appointments = new AppointmentCollection();

this.RadScheduler1.DataSource = appointments.GetAppointmentsByDate("08/19/2011");

As well, if it proves helpful...the offending JS line of code is below. I can shift-F9 and see that my scheduler control "ctl00_ContentPlaceholder1_RadScheduler1" is populated w/all of the correct data from my binding code...it's just that the "Telerik.Web.UI.RadScheduler" is null

Telerik.Web.UI.RadScheduler._preInitialize("ctl00_ContentPlaceHolder1_RadScheduler1",0,0,1,false);

Thanks in advance for any advice!
