前台：

<aspinkButton ID="LinkButton1" runat="server" CommandArgument=＇<#DataBinder.Eval(Container.DataItem,"id")>＇>我要报名</aspinkButton>

后台：  

  protected void dltFandian_ItemCommand(object source, DataListCommandEventArgs e)

    {

        if (e.CommandName == "SeeDetails")

        {

            string fandianid = this.dltFandian.DataKeys[e.Item.ItemIndex].ToString();

            string chengshiid = Request.QueryString["id"].ToString();

            Response.Redirect("~/fandianxiangxi.aspx?fandianid=" + fandianid + "&id=" + chengshiid);

        }

    }
