代码如下：

<mobile:ObjectList ID="objlist" Runat="server" ItemsPerPage="1" OnItemDataBind="Obj_LoadItems">
           <DeviceSpecific Runat="server">
             <Choice>
               <ItemTemplate>
                  <mobile:Label Runat="server">Question:</mobile:Label>
                  <mobile:Label Runat="server"><%#((ObjectListItem)Container)["Question"] %></mobile:Label>
                  <mobile:Label Runat="server" ID="QKey"><%#((ObjectListItem)Container)["QuestionKey"] %></mobile:Label>
                  <mobile:Label Runat="server">Answer:</mobile:Label>
                  <mobile:SelectionList Runat="server" SelectType="DropDown" ID="dpAnswer">
                    <Item Text="------------Please select--------------" Value="0" />
                  </mobile:SelectionList>
                  <mobile:TextBox ID="TxAnswerInput" Runat="server" />
               </ItemTemplate>
             </Choice>
           </DeviceSpecific>

现在想提取Qkey的text属性值，如何找到这个控件？谢谢
