datalist取消编辑状态
前台代码:

                                </tr>
                            </table>
                        </ItemTemplate>
                    </asp:DataList>


后台代码:
public partial class Car : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            bindDatalist();
        }
    }

    private void bindDatalist()
    {
        //获取传入购物车,绑定数据
        this.DataList1.DataSource = Session["Cartit"];
        int count = 0;
        foreach (CartItem item in (ICollection)Session["cartit"])
        {
            count++;
        }
        this.count.Text = count.ToString();
        this.DataList1.DataBind();


    }
    protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)
    {
        if (("Edit"))
        {
        this.DataList1.EditItemIndex = e.Item.ItemIndex;
        bindDatalist();
        }
        //else if (("Update"))
        //{
        //    Label la1 =(Label) e.Item.FindControl("itemid");
        //    int itemid=int.Parse(la1.Text);

        //    foreach (CartItem item in (ICollection)Session["cartit"])
        //    {
        //        if (item.Id==itemid)
        //       {
        //           item.Quantity++;
        //       }
        //    }

        //    DataList1.EditItemIndex = -1;
        //    bindDatalist();
        //}
    }
    protected void DataList1_CancelCommand(object source, DataListCommandEventArgs e)
    {
        DataList1.EditItemIndex = -1;
        bindDatalist();
    }
    protected void DataList1_UpdateCommand(object source, DataListCommandEventArgs e)
    {
        Label la1 = (Label)e.Item.FindControl("itemid");
        int itemid = int.Parse(la1.Text);

        foreach (CartItem item in (ICollection)Session["cartit"])
        {
            if (item.Id == itemid)
            {
                item.Quantity++;
            }
        }
        Page.RegisterStartupScript("msg", "<script>alert('更新成功!')</script>");
        DataList1.EditItemIndex = -1;
        bindDatalist();

    }

这是一个购物车模块

进入编辑状态之后,输入新的商品熟练,点击更新按钮,从新绑定,但是,既不执行ItemCommand中关于update 的代码,也不执行Update事件,请问到底为什么,谢谢,这是我全部的分
