Ajax Question

Maping Events to FullCalender using JSON

Currentl Working on the jquery fullcalender, i've been unable to add events to it from code behind

I've tried all of these possible solutions but none of them worked for me really! I'm relatively new to AJAX/Json.



(AND EVERY OTHER POSSIBLE LINK)

This is my code

[WebMethod]

public static String TestOnWebService()
{
int i = 1;

string myJsonString = "";
List<object> myList = new List<object>();
dt = db.getPublicHolidays();

foreach (DataRow dr in dt.Rows)
{
var id = i;
var title = dr["name"].ToString();
var start = dr["startDate"].ToString();
var end = dr["endDate"].ToString();


//Convert Implicity typed var to Date Time
DateTime RealStartDate = Convert.ToDateTime(start);
DateTime RealEndDate = Convert.ToDateTime(end);


//Convert Date Time to ISO
String SendStartDate = RealStartDate.ToString("s");
String SendEndDate = RealEndDate.ToString("s");


Events t_table = new Events(id, title, start, end);


myList.Add(t_table);
i++;

}

myJsonString = (new JavaScriptSerializer()).Serialize(myList);
return myJsonString;

}

}


and my events class

public class Events
{
public int id { get; set; }
public String title { get; set; }
public String start { get; set; }
public String end { get; set; }

public Events(int id2, String I, String t, String ds)
{
this.id = id2;
this.title = I;
this.start = t;
this.end = ds;
}


}


Here is the front end code

events: function (start, end, callback) {
$.ajax({
type: "POST", //WebMethods will not allow GET
url: '<%= ResolveUrl("EmpHolidays.aspx/TestOnWebService") %>', //url of a webmethod - example below
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (doc) {
var events = []; //javascript event object created here
var obj = $.parseJSON(doc.d); //.net returns json wrapped in "d"

for(var i=0;i<obj.length;i++){
console.log(obj[i]['id']);
console.log(obj[i]['title']);
console.log(obj[i]['start']);
console.log(obj[i]['end']);
}


$(obj.event).each(function () { //yours is obj.calevent
events.push({
title: $(this).attr('title'), //your calevent object has identical parameters 'title', 'start', ect, so this will work
start: $(this).attr('start'), // will be parsed into DateTime object
end: $(this).attr('end'),
id: $(this).attr('id')
});
});
callback(events);
}
});
}


This is the result i get

Any sort of help/hint would be appreciated!

SO AFTER THREE DAYS OF STRUGGLE, I GOT IT TO WORK! I added events from database to add to the jquery fullcalender. this is what solved my problem! Here is my code

Here is the code behind function which returns json data from db

[WebMethod]
        public static String TestOnWebService()
        {
            int i = 1;

            string myJsonString = "";
            List<object> myList = new List<object>();
            dt = db.getPublicHolidays();

            foreach (DataRow dr in dt.Rows)
            {
                        var id = i;
                        var title = dr["name"].ToString();
                        var start = dr["startDate"].ToString();
                        var end = dr["endDate"].ToString();


                        //Convert Implicity typed var to Date Time
                        DateTime RealStartDate = Convert.ToDateTime(start);
                        DateTime RealEndDate = Convert.ToDateTime(end);


                        //Convert Date Time to ISO
                        String SendStartDate = RealStartDate.ToString("s");
                        String SendEndDate = RealEndDate.ToString("s");

                       //string start2 = ((RealStartDate.Ticks - 621355968000000000) / 10000000).ToString();
                       //string end2 = ((RealEndDate.Ticks - 621355968000000000) / 10000000).ToString();

                Events t_table = new Events(id, title, SendStartDate, SendEndDate);


                        myList.Add(t_table);
                        i++;

                    }

            myJsonString = (new JavaScriptSerializer()).Serialize(myList);
            return myJsonString;

            }
    }

AND MY EVENTS CLASS

public class Events
{
    public int id { get; set; }
    public String title { get; set; }
    public String start { get; set; }
    public String end { get; set; }

    public Events(int id2, String I, String t, String ds)
    {
        this.id = id2;
        this.title = I;
        this.start = t;
        this.end = ds;
    }


}

HERE IS THE OUTPUT :D :D
