The e argument of EventClick handler (EventClickEventArgs) holds is the value of the clicked event (DataValueField) in e.Value.

protected void DayPilotCalendar1_EventClick(object sender, EventClickEventArgs e)
{
  Label1.Text = "Selected event: " + e.Value;
}

TimeRangeSelected knows the time clicked

protected void DayPilotCalendar1_TimeRangeSelected(object sender, TimeRangeSelectedEventArgs e)
{
  Label1.Text = "Selected time: " + e.Start;
}
