里面的值怎么绑定啊，后台绑定不用SqlDataSource..

Answer 1

用findControl先找到cityDpt，
然后直接像正常的控件一样绑定就可以了。

Answer 2

在绑定事件里FindControl("cityDpt") as DropDownList ,然后对DropDownList 进行数据源的提供和绑定即可

Answer 3

 在GridView 的 datarowround 的事件里找 到  dropdownlist 控件  
 然后在这个事件内。
 绑定数据。
  如： protected void gv_RowDataBound(object sender, GridviewRowEventArgs e)
        {
           DropDownList dr= (DropDownList )e.Item.FindControl("cityDpt");
             dr.DataValueField = "标识ID";
             dr.DataTextField = "标识NANE";
             dr.DataSource = 数据源;    
         }  

Answer 4

<asp:DropDownList ID="ddlValues" Width="106px" DataTextField="PV_Value" DataSource='<%# Values %>' DataValueField="PropertyValues_ID" runat="server"></asp:DropDownList>
if(ViewState["values"] == null)
                    ViewState.Add("values", null);
public List<PropertyValues> Values//父属性值集合
        {
            get { return (List<PropertyValues>)ViewState["values"]; }
            set { ViewState["values"] = value; }
        }页面加载时候给Values赋值
