Store the objects in hidden Field and Retrive from serverside

Store the objects in hidden Field and Retrieve from server side:-
      We can not store the objects in hidden field, but we can store using JSON.stringify to convertt the objects to string and store it to hidden field and access it from server side, but in server side we should need to serialize using JavaScriptSerializer and Deserialize.

Example:-
Client Side

var searchFilter = new Object();
searchFilter.ReportType = $('#<%=hdval.ClientID %>').val();
searchFilter.CompanyID = $("#<%=ddlCompany.ClientID%>").val();
searchFilter.CategoryID = $('#<%= HDtypeID.ClientID %>').val();
searchFilter.JobTitleID = jt;
searchFilter.Month = mnth;
searchFilter.Year = yar;
searchFilter.MonthCheck = $('#<%=HDmnthChk.ClientID %>').val();
searchFilter.FromDate = dt;
searchFilter.ToDate = dt1;
searchFilter.EmployeeID = EmpID;
searchFilter.ShiftID = shft;
searchFilter.DirectReportTo = rpto;

//Store the object values in hidden Field through string
var jsonSearchText = JSON.stringify(searchFilter);
$("#<%=hdnSearchFilter.ClientID %>").val(jsonSearchText);

Server Side

//Call the function and assign the value from objects
SearchFilter objSearch = new SearchFilter();
objSearch = GetSearchFilter();

objSearch.ReportType
objSearch.CompanyID
objSearch.CategoryID
objSearch.JobTitleID
objSearch.FromDate
objSearch.ToDate
objSearch.Monthcheck
objSearch.Month
objSearch.Year
objSearch.EmployeeID;
objSearch.ShiftID
objSearch.DirectReportTo

//Assign the value to class from hidden field converted object string
public class SearchFilter
{
    public string ReportType { set; get; }
    public int CompanyID { set; get; }
    public int CategoryID { set; get; }
    public int JobTitleID { set; get; }
    public string FromDate { set; get; }
    public string ToDate { set; get; }
    public int Monthcheck { set; get; }
    public int Month { set; get; }
    public int Year { set; get; }
    public int EmployeeID { set; get; }
    public int ShiftID { set; get; }
    public int DirectReportTo { set; get; } // 0 - Default  1-Show Direct Report
}

public SearchFilter GetSearchFilter()
{
    //Store the Hidden Filed value to str
    string str = hdnSearchFilter.Value;
    JavaScriptSerializer objSerilize = new JavaScriptSerializer();
    SearchFilter objRes= (SearchFilter) objSerilize.Deserialize(str, typeof(SearchFilter));
    return objRes;
}
