           int Id = int.Parse(DropDownList1.SelectedValue);
          fn_BindGrid(Id);
       }

           Con = new SqlConnection("Connection String");
           Con.Open();
           Cmd= new SqlCmd("Select * from Table Where Id = @Id",Con)
           Cmd.parameters.AddWithValue("@Id",Id)
           dt = new SqlDataAdapter(Cmd);
