Hello -- I looked through the forum to see if I could find something similar to the problem I'm experiencing, but did not.
I have implemented a Scheduler using a custom data provider. I can create appointments fine, however when I try to edit them I'm receiving the error below. Specifically, this error occurs when I double-click the appointment I wish to edit, choose to "Edit the Series", and then click the "More" link to view the AdvancedEdit window. Editing a single occurrence of an appointment in AdvancedEdit mode works fine, whether the appointment is actually recurring or not.
Here's the error:

Any ideas on what could be causing this? Let me know if you need more info.

Hello Trevor,
By default, selecting the "Edit the Series" option automatically opens the advanced edit form. I tested the
XML Scheduler Provider online example and I was able to edit the series without problems.
Could you open a support ticket and send us a small project which demonstrates the problem?

Thanks for the reply, Peter. I actually solved the problem over the weekend. I had a hunch there was something I wasn't doing right and sure enough, I found that I had left out a key step in implementing my DataProvider. I hadn't given the RadScheduler a reference to the Provider object and had overloaded the Insert, Update, Delete, etc events in the code-behind with manual calls into the provider methods. The effect was more akin to a DataSource integration than a DataProvider. It worked though -- except for that one scenario.
In any case, I solved my problem. Thanks.
