I have following webmethod where i want to modify the value of the existing Session variable but here inside the webmethod whenever i assign the value to that session variable, the value is not assigning to it.
WEBMETHOD
[WebMethod(EnableSession = true)]
public static List<tblCustomerList> CustData(String id)
{
Int32 count=(Int32) HttpContext.Current.Session["pgnum"];
HttpContext.Current.Session["pgnum"] = count++;
DataGridEntities _dbContext = new DataGridEntities();
var filteredResult = _dbContext.tblCustomerLists.ToList();
return filteredResult;
}
In your code you should do like this, because count++ will assign the existing value and then increment its value
HttpContext.Current.Session["pgnum"] = ++count;
