The data source 'ObjectDataSource1' does not support sorting with IEnumerable data. Automatic sorting is only supported with DataView, DataTable, and DataSet.

trans = I_session.BeginTransaction();

IList Lst = new List();

Lst = I_session.CreateCriteria().Add(Restrictions.Disjunction()

.Add(Restrictions.Eq("Cityname", "Karachi"))

.Add(Restrictions.Eq("Cityid", 2))).List();



string CustomerQuery = "select cust.* from Customer cust inner join city c on c.cityid=cust.cityid";

ISQLQuery oIqueryCustomer = I_session.CreateSQLQuery(CustomerQuery).AddEntity(typeof(Customers));

lstCustomerExtract = oIqueryCustomer.List();

foreach (Customers cust in lstCustomerExtract)

{

Cusomer_City oCusomer_City = new Cusomer_City();


lstCityExtract = I_session.CreateCriteria(typeof(City)).Add(Restrictions.Eq("Cityid", cust.Cityid)).List();



oCusomer_City.CustomerName = cust.CustomerName;

oCusomer_City.CustomerId = cust.CustomerId;

oCusomer_City.CustomerAddress = cust.CustomerAddress;

oCusomer_City.Cityid = lstCityExtract[0].Cityid;

oCusomer_City.Cityname = lstCityExtract[0].Cityname;

oCusomer_City.Gender = cust.Gender==1?"Male":"Female";

ooCusomer_City.Add(oCusomer_City);

}
