Hi Gaurav I have mentioned in where condition like branch_2 so both will show dept_2_1 and dept_2_2 try like MyDBDataContext sqlObj = new MyDBDataContext (); var employees = from Office in sqlObj.tblEmployees where emps. branch= branch_2_2 orderby emps.EmployeeName select new { emps.EmployeeID emps.EmployeeName emps.Salary }; gvemployees.DataSource = employees; gvemployees.DataBind(); Before please check what is identify column name particular user is branch_2_1 ?
