Hi!

I'm trying to reproduce the resource availability demo using ObjectDataSources instead. Trying to build the code from scratch to get to know the component. As soon as I set DataSourceId referencing an ObjectDataSource on either the Scheduler or a ResourceType the scripts from WebResource is not included in the page. Before I add the datasource, two scripts are loaded and it checks whether Sys is undefined, but when the datasource is set, the scripts are not there and it just attempts to start the initialization.
I use the Q1 2011 version.

Any ideas?
Here's the code:
(If you remove DataSourceID, GroupBy and ResourceTypes, it works fine, otherwise scripts is not loaded)

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Scheduler.aspx.cs" Inherits="TelerikPrototyping.Scheduler" %>

<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>

Never mind the Session state of the data sources - that will change when everything works. ;)

Hello Lars-Erik,

Thank you for the attached project.

Yes, I've been able to reproduce the issue however even with commented GroupBy and ResourceTypes I am still getting an error "Sys is undefined" and "Telerik is undefined". That makes me think that your web application is not configured to work with AJAX.

Please take a look at this blog post and this "General Troubleshooting" help article and let me know if this helps.

Hi again!

We managed to pinpoint the source of the error.
It works as soon as we don't set the objectdatasources instance to the page instance. (The OnDataSourceCreating event)
This is something that is part of our general architecture choice (MVP) and should definately not affect UI components.

Edit:
My colleague just managed to make it work by moving everything into a usercontrol.
Please consider this a bug report.
