DataGrid问题--新手求救

*.aspx 中<%# DataBinder.Eval(Container.DataItem, "序号")%>得不到值
 *.aspx.cs中private void MyList_ItemCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e) 事件不执行,请问是怎么回事?
上面问题是在加入分页后才出现的

  2.   

    查看sql语句是否有这个字段！EnableViewState=true;
      

  3.

  4.   

    EnableViewState=true;没有啊，其它字段能正常显示
      

  5.   

    看看这个有没有帮助?
    <asp:datagrid id="grd1" runat="server" OnSortCommand="Sort_Grid" AllowSorting="True" CssClass="Table" Width="100%" AllowPaging="True" BorderColor="#5A5A5A" PageSize="5">
    <SelectedItemStyle CssClass="TableSelect"></SelectedItemStyle>
    <AlternatingItemStyle CssClass="TableAltern"></AlternatingItemStyle>
    <ItemStyle CssClass="TableItem"></ItemStyle>
    <HeaderStyle CssClass="TableHead"></HeaderStyle>
    <Columns>
    <asp:TemplateColumn>
    <HeaderStyle Width="30px"></HeaderStyle>
    <ItemStyle HorizontalAlign="Center"></ItemStyle>
    <HeaderTemplate>
    <FONT size="2">选择</FONT>
    </HeaderTemplate>
    <ItemTemplate>
    <asp:CheckBox id=CheckBox1 Height="10px" ToolTip='<%# DataBinder.Eval(Container.DataItem,"单据编号") %>' Runat="server">
    </asp:CheckBox>
    <asp:Label ID="edit_billid" Visible=False Runat=server text='<%# DataBinder.Eval(Container.DataItem,"单据编号") %>'/>
    </ItemTemplate>
    </asp:TemplateColumn>
    </Columns>
    <PagerStyle Visible="False" NextPageText="后页" Height="23px" PrevPageText="前页" HorizontalAlign="Center" CssClass="TablePage" Mode="NumericPages"></PagerStyle>
    </asp:datagrid>
      

  6.   

    取值可以:((Label)grd1.Items[i].Cells[0].FindControl("edit_billid")).Text.ToString()
      

  7.   

    .cs文件中private void MyList_ItemCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e) 事件还是不能执行,请各位继续发表高见，小弟在这里多谢了?
      

  8.   

    Page_Load里是否有 if(!this.Page.IsPostBack){}
