Question

.net中的dropdownlist通过一个变量改变选择相同的DataValueField

            string sqlstr = "select eid,e_name from EM_Equipment_info ";            sqlcon = new SqlConnection(strCon);            SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);            DataSet myds = new DataSet();            sqlcon.Open();            myda.Fill(myds, "EM_Equipment_info");            eid.DataSource = myds.Tables["EM_Equipment_info"].DefaultView;            eid.DataTextField = "e_name";            eid.DataValueField = "eid";            eid.DataBind(); 下面要做的就是假如我有一个变量eid1如何让dropdownlist控件eid能默认选择其datavaluefield同eid1相同的一项

Answer 1

eid.SelectValue=eid1;
这样就好了，如果是按照textfield找的话
eid.Items.FindByText("关键字").Selected=true;
