The eventResizeCallBack() method executes the server-side EventResize handler using an AJAX callback.
This only applies to ASP.NET WebForms, ASP.NET MVC and Java versions.
DayPilot.Scheduler.eventResizeCallBack(e, newStart, newEnd, data)e (DayPilot.Event) - object reference
newStart (DayPilot.Date) - updated start
newEnd (DayPilot.Date) - updated end
data (object) - additional custom data
Use this legacy helper to trigger the server-side EventResize pipeline from client-side code and send the updated time range and any custom data in the callback request.
dp.eventResizeCallBack(e, newStart, newEnd, { reason: "resize" });Sending Custom Data with CallBack
