I am evaluating the RadScheduler feature, and have followed the samples, and cannot make a custom datasource work. Here's what I did:
1) Created a new AJAX enabled website
2) Added RadManager, added RadScheduler and setup.
3) Created a provider as an instance of DbSchedulerProviderBase
4) Deliberately left the Insert and Update events as they come (throw an exception)
5) Hardcoded 2 appointments
6) The scheduler displays fine. The dra-and-drop feature raises an exception, which is what I expected.
7) When I open the dialog to insert or edit, it displays correctly; however, it does not raise an exception, which is what was expected.
I am getting ready to throw the towel on this. Below, I have copied the code for this mini project; I wonder if anybody can help me. Thanks.

Everything looks alright with your provider. The problem seems to be the call to Rebind() in Page_Load. Removing it should resolve the issue.
