    I am getting an error when trying to bind a timeslot view over multiple days. Sometimes it works, sometimes it doesn't. I've traced it down to the "NumberOfSlots" variable. When I bind certain data, it won't go over 250. However, with some data it works fine with a value of 2500. I've pasted below a code snippet of a page that return the error. Any ideas as what could be causing this?

    Hi Ron,

    We tested your code (slightly modified) with our own datasource, but we could not replicate the problem. Please, see the attached sample for reference. To be able to assist you further, please open a support ticket and send us a working demo that we can test locally.

    Kind regards,

    Dear Support,

    I have a similar problem except the binding error occurs when I attempt to bind more than 364 records. 

    Can I view the solution that was offered to the original poster of this thread?  Or can someone explain how to get around this limitation?

    Hello Josh,

    When Peter debugged the application of Ron, he found that Ron is setting NumberOfSlots to a value larger than 2000 (not 200). 2000 is a way too many slots for RadScheduler to render. The maximum number that you can set NumberOfSlots to is 359, which Peter found empirically. Our suggestion is to reorganize RadScheduler in such a way as to not to exceed this number.

    All the best,
