I got one issue with RadSchedulerRecurrenceEditor. In my test project, I created 2 items (Test 1 and Test 2) in the test RadGrid. For Test 1, I assigned an Appointment instance where the RecurrenceEditor is a regular Hourly recurrence (Test1RecurrenceEditor.PNG). For Test 2, I assigned a new Appointment where the RecurrenceEditor is an Hourly recurrence with EndAfter (Test2RecurrenceEditor.PNG). I saved after I created each. Test 2 was selected. After I clicked on Test 1, my project threw the exception of "Sys.WebForms.PageRequestManagerServerErrorException: Cannot have multiple items selected".
If you have seen this before, can you please help? Thank you.
