问题描述
我正从具有roomno的数据库中获取下拉列表绑定。作为textfield和guestid的值如：
roomno = 102，GuestID = 2;
romno = 103，guestid = 2;
roomno = 104，guestid = 1;
当我们将这些数据绑定到下拉列表并选择roomno：103时，它将始终选择具有相同值的第一个索引上的项目（如roomno 102和103都有相同的猜测，即2）
我如何选择具有相同值的下一个索引上的项目;
plz recommended我的任何解决方案....

i am having a drop down list bind from database having roomno. as textfield and guestid as value like :
roomno=102, GuestID=2;
romno=103, guestid=2;
roomno=104, guestid=1;
when we bind this data to drop down list and select roomno: 103 it will always select the item on first index with same value (as roomno 102 and 103 both having same guestid i.e. 2)

推荐答案
ddlRoomNo.SelectedIndex = ddlRoomNo.Items.IndexOf(ddlRoomNo.Items.FindByText("103"));
