Datalist里如何绑定DropDownList的值

一个DropDownList在DataList里 我想把数据库的某一个字段值绑定到DropDownList里！该怎么绑定啊？在后台取不到DropDownList的ID啊！

Answer 1

绑定在DataList中的DropDownList

private void dlistOrder_EditCommand(object source, System.Web.UI.WebControls.DataListCommandEventArgs e)
{
//绑定订单状态
for(int i=0;i<((DropDownList)dlistOrder.Items[e.Item.ItemIndex].FindControl("ddlFlag")).Items.Count;i++)
{
if(((DropDownList)dlistOrder.Items[e.Item.ItemIndex].FindControl("ddlFlag")).Items[i].Value == dv.Table.Rows[0]["OrStatus"].ToString())
{
((DropDownList)dlistOrder.Items[e.Item.ItemIndex].FindControl("ddlFlag")).Items[i].Selected = true;
}
}
}

Answer 2

DataSet ds= new DataSet();
ds=数据库查询方法(要返回DataSet类型的额)
dsCountry = dbaccessor.ManualSqlQuery("select A , B from 表);
ddlCountry.DataSource = ds;
ddlCountry.DataTextField = "B";
ddlCountry.DataValueField = "A"; (一般为 ID )
ddlCountry.DataBind();

Answer 3

在后台用DataList.Controls["DropDownList的名字"]取到DropDownList，然后绑定吧！
