内容页中Repeater的Div获取,该怎么解决

内容页中Repeater的Div获取
母版页为A 内容页为B
B.aspx

<asp:Content ID="Content1" ContentPlaceHolderID="content" runat="server">

      <div class="divSTBody">

    <asp:Repeater ID="Repeater1" runat="server" >

    <ItemTemplate> 


          <div  class="divQuestion" id="question<%#Eval("id") %>" onclick="controlchild('answer<%#Eval("id") %>')">

              <div id="STContentDiv" runat="server"></div> 

          </div>


    </ItemTemplate>

    </asp:Repeater>

   

    </div>


</asp:Content>

B.aspx.cs

  protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)

        {             

            DataRowView drv = (DataRowView)e.Item.DataItem;

          //在不使用母版页的时候，可以这样写

           //  HtmlGenericControl divTemp = e.Item.FindControl("STContentDiv") as HtmlGenericControl;

          在使用母版页后该怎么写呢

------解决思路----------------------
与母版没关系，写法一样!!!
