AJAX :: Populate DatePicker With Dates From JQuery

protected void Page_Load(object sender, EventArgs e) {
Session["ID"] = "2";
string strConnString = ConfigurationManager.ConnectionStrings["BSDConnectionString"].ConnectionString;
var con = new SqlConnection(strConnString);
using (var sda = new SqlDataAdapter()) {
SqlCommand cmd = new SqlCommand();

[Code] .....

That was my code , now lets see what my problem is :

I am getting only two dates in a single row from sql to my asp.net webform and then bindng those dates in jQuery UI Datepicker. Now if i set session to 1 then date picker works well but if i put session = 2 , it shows the end date till 2020 which is wrong.

Below are the dates which are fetched from database and i have copied here....

When Session["ID"] = "1";

Start Date : 01/07/2014 00:00:00
End Date :   05/02/2015 00:00:00   

When Session["ID"] = "2";

Start Date : 07/04/2015 00:00:00
End Date :   27/08/2016 00:00:00      

I have set my mindate to startdate and maxdate to end date....

Also point of interest is that if i don't fetch values from database and use only List<string> in my web method then every thing works well. Like this :

[WebMethod]
public static List<string> GetDates() {
List<string> arr = new List<string>();
arr.Add("2014-07-01");
arr.Add("2015-02-05");
return arr;
}
