The eventMovePostBack() method executes the server-side EventMove handler using a PostBack (ASP.NET WebForms only).
DayPilot.Scheduler.eventMovePostBack(e, newStart, newEnd, newResource, data)e (DayPilot.Event) - object reference
newStart (DayPilot.Date) - updated start
newEnd (DayPilot.Date) - updated end
newResource (string) - updated resource id
data (object) - additional custom data
Use this legacy helper to trigger the server-side EventMove pipeline from client-side code and send the updated start, end, resource, and any custom data using a PostBack request.
