Hi Dan,
I did have the Event and Edit handlers set to CallBack in my codebehind. I changed this and started using the e.start, e.end and e.columnId in the Event and Edit as you stated. I am now receiving, in the return of the start variable,
"function() { return new Date(object.getAttribute(\"dpStart\")); }"
which I expect the start information, like a time or something. What am I doing wrong to receive the string above from a click on the event?

DataEndField="ET" DataStartField="BT" DataTextField="Event" DataValueField="Resource_Name"

TimeRangeSelectedJavaScript="openPopup(start,end,column);"

</DayPilot:DayPilotCalendar>
function openPopup(start, end, column) {
window.open('Reservation.aspx?start=' + start + '&end=' + end + '&column=' + column ,'PopupDetail','width=535,Height=360,top=200,left=100' );
}
