使用DataList1_ItemDataBound的事件丢失问题

 protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            dataBind();
        }
    }

    private void dataBind()
    {
        FactorData factordata = (new FactorSystem()).FactorSecondListSystem(6, 101, 1, 20);
        DataList1.DataSource = factordata;
        DataList1.DataBind();
    }

    protected void DataList1_ItemDataBound(object sender, DataListItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            DataRowView dv = (DataRowView)e.Item.DataItem;
            LinkButton LinkButton1 = (LinkButton)e.Item.FindControl("LinkButton1");
            LinkButton1.Text = dv.Row["description"].ToString();

            LinkButton1.CommandArgument = dv.Row["factorID"].ToString();
            LinkButton1.Click += new EventHandler(LinkButton1_Click);
        }
    }

    protected void LinkButton1_Click(object sender, EventArgs e)
    {
        LinkButton LinkButton1 = (LinkButton)sender;
        Response.Write(LinkButton1.CommandArgument);
    }

如果是这样在ItemDataBound事件中给LinkButton按钮设定Click时间，则事件回发的时候给DataList数据绑定的dataBind()一定不要判断IsPostBack，否则事件会丢失。解决的问题方法是
<asp:LinkButton ID="LinkButton1" runat="server" CommandArgument='<%# Eval("factorID")%>'
                            onclick="LinkButton1_Click1"><%# Eval("description")%></asp:LinkButton>
直接在aspx页面绑定就可以了。
