in my case week start day is a variable (var weekstart = 1;1-mon,2-tue … 7-sunday).
how can i set the week start date using scheduler.date.week_start function ?

Hi,

PLease try this

[code]if(strWeekStartDay==“SUNDAY”)
intDayId = 0;
else if(strWeekStartDay==“MONDAY”)
intDayId = 1;
else if(strWeekStartDay==“TUESDAY”)
intDayId = 2;
else if(strWeekStartDay==“WEDNESDAY”)
intDayId = 3;
else if(strWeekStartDay==“THURSDAY”)
intDayId = 4;
else if(strWeekStartDay==“FRIDAY”)
intDayId = 5;
else if(strWeekStartDay==“SATURDAY”)
intDayId = 6;

    if(scheduler.getState().mode=="week"){
        
        scheduler.date.week_start = function(date) {
            var shift = date.getDay();
            if (shift === 0)
                shift = 2;
            else
                shift = shift - intDayId;                
            return this.date_part(this.add(date, -1 * shift, "day"));
        };
    }[/code]

will this work if onload mode is ‘month’ and user changes it to ‘week’ mode ?

Hi ,

Put the week start function inside the onViewChange event , so that it will call on every view change

scheduler.attachEvent(“onViewChange”, function (new_mode , new_date){
//any custom logic here
});

$scope.schedulerInstance.date.week_start = function(date){
console.log(date);
var intDayId = 0;
if($scope.schedulerconfig.weekStartDay==7)
intDayId = 0;
else if($scope.schedulerconfig.weekStartDay==1)
intDayId = 1;
else if($scope.schedulerconfig.weekStartDay==2)
intDayId = 2;
else if($scope.schedulerconfig.weekStartDay==3)
intDayId = 3;
else if($scope.schedulerconfig.weekStartDay==4)
intDayId = 4;
else if($scope.schedulerconfig.weekStartDay==5)
intDayId = 5;
else if($scope.schedulerconfig.weekStartDay==6)
intDayId = 6;

							var shift = date.getDay();
			                if (shift == 0)
			                    shift = 2;
			                else
			                    shift = shift - intDayId;                
			                return this.date_part(this.add(date, -1 * shift, "day"));
						};

what you have gien is working fine but in the month view when ever month starts with sunday then it is not working correctly.

this worked for me

$scope.schedulerInstance.date.week_start = function(date){
var intDayId = 0;
if($scope.schedulerconfig.weekStartDay==7)
intDayId = 0;
else if($scope.schedulerconfig.weekStartDay==1)
intDayId = 1;
else if($scope.schedulerconfig.weekStartDay==2)
intDayId = 2;
else if($scope.schedulerconfig.weekStartDay==3)
intDayId = 3;
else if($scope.schedulerconfig.weekStartDay==4)
intDayId = 4;
else if($scope.schedulerconfig.weekStartDay==5)
intDayId = 5;
else if($scope.schedulerconfig.weekStartDay==6)
intDayId = 6;

							var shift = date.getDay();
			                if(shift ==0)
			                {
			                shift = 7- $scope.schedulerconfig.weekStartDay;
			                }
			                else
			                {
			                shift = shift - intDayId; 
			                }
			                      
			                if(shift < 0)
			                	{
			                	shift = 7 + shift
			                	}
			                return this.date_part(this.add(date, -1 * shift, "day"));
						};
