Thanks for prompt reply.
I replaced 3.0.210.0 with 8.1.3505.1
Needed to change
protected void DayPilotCalendar1_EventClick(object sender, DayPilot.Web.Ui.Events.EventClickEventArgs e)
to
DayPilot.Web.Ui.Events.EventClickEventArgs
but not sure what to do about
protected void DayPilotCalendar1_FreeTimeClick(object sender, DayPilot.Web.Ui.FreeClickEventArgs e)
Am i doing something wrong?
