dear all
asp.net版本为1.1
server为windows2003
我在datagrid里使用ItemTemplate放一个label
binddata后要把值塞入ItemTemplate里的label
但却没有动静
请问是那里出了问题
谢谢

default.aspx
<asp:datagrid id="dgFavorClass" runat="server" AutoGenerateColumns="False" DataKeyField="Fid">
                      <FooterStyle></FooterStyle>
                      <SelectedItemStyle></SelectedItemStyle>
                      <ItemStyle ></ItemStyle>
                      <HeaderStyle></HeaderStyle>
                      <Columns>
                        <asp:TemplateColumn HeaderText="序号">
                          <ItemTemplate>
                              <asp:Label id="lblSn" runat="server"></asp:Label>
                          </ItemTemplate>
                        </asp:TemplateColumn>
                        <asp:TemplateColumn HeaderText="排序"></asp:TemplateColumn>
                        <asp:TemplateColumn HeaderText="类别名称"></asp:TemplateColumn>
                      </Columns>
                      <PagerStyle HorizontalAlign="Left" Mode="NumericPages"></PagerStyle>
                    </asp:datagrid>

   public string DSN = ConfigurationSettings.AppSettings["OLECN"];

      myCmd_DG.Fill(ds, "FavorClass");

      dgFavorClass.DataBind();
    }

      if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
