【Linq to SharePoint】对列表查询的分页技术

1. 下面是用AspNetPage来分页的，主要在网站在有一个列表名称为新闻列表，BindGridView是一个分页的函数。

    下面的主要是对一个列表的查询进行的分页。

   后台代码

 EntityList<新闻列表项目> newsList;
        public const int PageSize = 10;
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!Page.IsPostBack)
            {
                BindGridView(GridView1.PageSize, 1);
            }
        }
        /// <summary>
        /// 绑定GridView控件
        /// </summary>
        /// <param name="pagesize">一页的条数</param>
        /// <param name="pageindex">页码数</param>
        protected void BindGridView(int pagesize, int pageindex)
        {
            var dc = new SPLinqDataContext(SPContext.Current.Web.Url);
            newsList = dc.GetList<新闻列表项目>("新闻列表");
            GridView1.PageSize = PageSize;
            AspNetPager1.PageSize = PageSize;
            var q = (from n in newsList
                    where n.Id != null
                    select new { n.Id,n.点击次数, n.标题 })
                    .Skip((pageindex - 1) * PageSize).Take(PageSize);
            AspNetPager1.RecordCount = q.Count();
            GridView1.DataSource = q;
            GridView1.DataBind();
        }
        protected void AspNetPager1_PageChanged(object sender, EventArgs e)
        {
            GridView1.PageIndex = AspNetPager1.CurrentPageIndex;
            BindGridView(GridView1.PageSize, AspNetPager1.CurrentPageIndex);
        }

  前台代码：

    <div>
        <asp:GridView ID="GridView1" runat="server">
        </asp:GridView>
    </div>
    <div>
        <webdiyer:AspNetPager ID="AspNetPager1" runat="server" PageIndexBoxType="DropDownList" ShowPageIndexBox="Always"
            SubmitButtonText="Go" TextAfterPageIndexBox="页" TextBeforePageIndexBox="转到" CurrentPageButtonPosition="End"
            CustomInfoHTML="共%PageCount%页，当前为第%CurrentPageIndex%页，每页%PageSize%条" FirstPageText="首页"
            LastPageText="尾页" NextPageText="下一页" OnPageChanged="Pager_PageChanged" PrevPageText="上一页">
        </webdiyer:AspNetPager>
    </div>
