                                </ItemTemplate>
</asp:Repeater>

//删除
        protected void imgbtnDel_Click(object sender, CommandEventArgs e)
        {
            string fiid = e.CommandName.ToString();
            favoriteinfoController fc = new favoriteinfoController();
            if (fc.DelFavoriters(fiid))
            {
                PagerDateBind();
                InfoBind();
                this.lbMsg.Text = "删除成功！";
            }
            else
                this.lbMsg.Text = "删除失败，请您重试！";
        }
