Resource index out of range: 1

[Tom Graham]

I am using the Drag and Drop integration example. When I drag a row from the RadGrid onto the scheduler while the scheduler is group by resources I get the error "Resource index out of range: 1". This is the sample default.aspx.cs code I am trying to use. I have noted that when grouped by resources the slotTargetindex format goes from "1:0:0" to "0:1:0:0". Any help would be appreciated.

Thanks, Tom

Hi Tom,

Please, try without calling Rebind():

private void HandleSchedulerDrop(int id, string subject, string targetSlotIndex)
        {
            RadScheduler1.Rebind();

All the best,

This does keep the error from occurring, but prevents the RadScheduler from being updated via Rebind(). In my code, I am using a ASP.NET timer to periodically update the schedule from it's data source. Is there another way to achieve this?

Hello Ashley,

Can you open a support ticket and send us a simple working demo of the issue?

Best wishes,

I found a work-around. In my code, I had a RadGrid and a RadScheduler in my project, and were linked via AJAX. 

I changed my Timer to call a Rebind() on the RadGrid object instead of the RadScheduler one, thus achieved the same end result without the error.
