After upgrading DLL version from (5.8.1956.0) to (8.1.3460.1), Events are not working

The latest version (8.1) still supports this syntax. What kind of error do you see?

Actually, the event(TimeRangeSelectedJavaScript="openPatientType(start, end, column);) is called ,it is true but when javascript function(openPatientType(start, end, column)) calls we cannot get parameters value in javascript code and not works split() on any variable.Function is described as below-

function openPatientType(start,end,column)
{
var LunchDate = DayPilot.ds(start); //here cannot get value of LunchDate , alert shows undefined
var sepDate = LunchDate.split('T'); //and split() not working

//Checking Past Appointment Start

var splitDatePart = sepDate[0].split('-');
var splitTimePart = sepDate[1].split(':');
var monthPart = splitDatePart[1];
if(monthPart=="08")
{
var monthpart_1=8;
}
else if(monthPart=="09")
{
var monthpart_1=9;
}
else
{
var monthpart_1 =parseInt(monthPart);
}

monthpart_1= monthpart_1 - 1;
var clickedStartDate = new Date(splitDatePart[0],monthpart_1,splitDatePart[2],splitTimePart[0],splitTimePart[1],splitTimePart[2]);
var todayDate = new Date();
if(new Date(clickedStartDate) < new Date(todayDate)) {
if (!confirm("You have selected a past time or date. Do you wish to continue?")) {
return false;
}
// var conf_result = returnValue();
// if (conf_result == 7) {
// return false;
// }

Please let us know How we can resolve this issue .

we are getting value in JavaScript 'undefined' if we use alert of start, end , column. please let us know how to resolve this .

In the latest version, "start" and "end" variables hold a DayPilot.Date object. You can get the the value as a string in ISO 8601 format by calling .toString():

var LunchDate = start.toString();
