怎么样实现把数据表格帮在MyDorpDownList
<body>
        <form   id= "form1 "   runat= "server ">
        <div   align= "center ">
        <asp:Repeater   ID= "MyRepeater "   runat= "server ">
        <ItemTemplate>
        <asp:DropDownList   ID= "MyDropDownList "   runat= "server "> </asp:DropDownList>
        </ItemTemplate>
        </asp:Repeater>
        </div>
        </form>
</body>


public   partial   class   Repeater   :   System.Web.UI.Page
{
        protected   void   Page_Load(object   sender,   EventArgs   e)
        {
                BindDropDownList();
        }

        public   SqlConnection   CreateConn()
        {
                SqlConnection   con   =   new   SqlConnection();
                con.ConnectionString   =   ConfigurationManager.AppSettings[ "SqlConnString "];
                con.Open();
                return   con;
        }

        public   void   BindDropDownList()
        {
                SqlConnection   conn   =   CreateConn();
                SqlDataAdapter   adapter   =   new   SqlDataAdapter();
                adapter.SelectCommand   =   new   SqlCommand( "select   *   from   a_cat   where   sid <> 0 ",conn);
                DataSet   ds   =   new   DataSet();
                adapter.Fill(ds,   "a_cat ");
                MyRepeater.DataSource   =   ds.Tables[ "a_cat "].DefaultView;
                MyRepeater.DataBind();
        }
}
问问,怎么样实现把表格a_cat   绑定在MyDorpDownList   上,当然Repeater上也要显示其他表的内容。

------解决方案--------------------
string sql = " ";
DataSet ds = DbHelperSQL.Query(sql);
this.MyDropDownList.DataTextField = "DirNameChs ";
this.MyDropDownList.DataValueField = "DirectoryID ";
this.MyDropDownList.DataSource = ds;
this.MyDropDownList.DataBind();
只能绑定两个字段阿,一个作为Text,一个作为Value;
不能把其他更多的字段绑定上ddl了
------解决方案--------------------
在Repeater的ItemDataBound事件中写
DropDownList dlist=e.Items.FindControls( "MyDropDownList ") as DropDownList
if(dlist!=null)
{
string sql = " ";
DataSet ds = DbHelperSQL.Query(sql);
this.MyDropDownList.DataTextField = "DirNameChs ";
this.MyDropDownList.DataValueField = "DirectoryID ";
