Daypilot recurrence events error

Asked by requirer

down vote

I have used the recurrence feature used by daypilot calendar as following :

protected void Calendar_BeforeEventRecurrence(DayPilot.Web.Ui.Events.Calendar.BeforeEventRecurrenceEventArgs e)

e.Rule = RecurrenceRule.FromDateTime(e.Value, e.Start).Weekly().Times(10);


but I'm getting an error : An entry with the same key already exists

I have also used the other way, the column where I store my rule . the rule is successfully saved but then in the databind of the calendar I get the same error as above which is An entry with the same key already exists

Can you please post the stack trace of the exception?

This looks like you are trying to store a new record with an existing ID in a place where unique IDs are enforced. It's not clear whether it comes from the database or from a DataSet/DataTable.

I'm not sure if you use BeforeEventRecurrence intentionally - this event is used for mapping rules stored using a custom mechanism (such as a special DB column with your own syntax) to DayPilot rules. If you use the DayPilot recurrence encoding implementation you typically don't need to use it (and you use DataRecurrenceField instead).
