  1.   

    用DataList里的每项都是个Item，然后你得到每项的Item对象，再用Item里的FindControl的方法去找到对应ID的控件，然后得到值
      

  2.   

    页面前台是这样的
    <asp:DataList ID="DataList1" runat="server" RepeatColumns="1">
                                        <ItemTemplate>
                                            <tr>
                                                <td>                                          
                                                    <table id="Table2" border="0" cellpadding="0" cellspacing="0" width="100%">
                                                        <tr>                                        
                                                                <td>       
                                                                    <%# DataBinder.Eval(Container.DataItem, "字段1")%>
                                                                    </td>
                                                        </tr>
                                                    </table>
                                              </td>
                                            </tr>
                                        </ItemTemplate>
                                    </asp:DataList>
    请问如何获取DataList中的某一个值?
      

  3.   

    DataList是一个数据集，你先确定，是怎样选取它的？点铵钮，还是点数据行，如后者，是单击还是双击？
    如果前者，铵钮是放在DataList行内，还是放在DataList外？
