GridView配合AspNetPager 进行 数据源分页的例子

很早就知道 可以用 陕西吴起娃 做的 AspNetPager  进行分页

在以前做的很多项目中也用过  效果不错 不过都是别人写的代码  我没有自己用过

今天做了一个例子  体验一下:

前台页面:

添加引用: <%@ Register Assembly="AspNetPager" Namespace="Wuqi.Webdiyer" TagPrefix="webdiyer" %>

 <webdiyer:AspNetPager ID="pagerNav" runat="server" AlwaysShow="True" ButtonImageNameExtension="n"
                CpiButtonImageNameExtension="r" CustomInfoText="" DisabledButtonImageNameExtension="g"
                Height="30" HorizontalAlign="right" ImagePath="../images" InputBoxStyle="border:1px #0000FF solid;text-align:center"
                NumericButtonTextFormatString="[{0}] " OnPageChanged="pagerNav_PageChanged" PageSize="3"
                PagingButtonSpacing="0" ShowBoxThreshold="10" ShowCustomInfoSection="left" SubmitButtonStyle="border:1px solid #000066;height:20px;40px"
                SubmitButtonText="GO" TextAfterInputBox="页" TextBeforeInputBox="转到第" Width="85%"
                NextPageText='<font face="webdings"></font>' PrevPageText='<font face="webdings"></font>'
                LastPageText='<font face="webdings"></font>' FirstPageText='<font face="webdings"></font>'>
            </webdiyer:AspNetPager>
           
            <asp:GridView EnableViewState="false" ID="GridView1" PageSize="3" runat="server" AllowPaging="True" AutoGenerateColumns="False">
                <Columns>
                    <asp:BoundField DataField="sID" HeaderText="sID" SortExpression="sID" />
                    <asp:BoundField DataField="sValue" HeaderText="sValue" SortExpression="sValue" />
                </Columns>
                <PagerSettings FirstPageText="首页" LastPageText="末页" NextPageText="&gt;" PreviousPageText="&lt;"
                    PageButtonCount="3" Visible="False" />
            </asp:GridView>

后台代码:

 protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            string sqlConnect = "Provider=SQLOLEDB;data source=HG-J3EJJ9LSW5PY;initial catalog =photomandb_dzrb;User ID=sa;password=hg;Connection Timeout=30";
            DataOperation.globalConnectionString = sqlConnect;
            DataSet ds = DataOperation.SelectDataBySql(@"

select sID,sValue,row from
(
  select *,ROW_NUMBER() OVER (ORDER BY sID asc) AS Row from tInfoParameter ) as temp
where row >=1 and row <=3

");

            GridView1.DataSource = ds.Tables[0].DefaultView;
            GridView1.DataBind();

            pagerNav.PageSize = 3;
            pagerNav.CurrentPageIndex = 1;
            pagerNav.RecordCount = 79;
        }

    }

    protected void pagerNav_PageChanged(object src, Wuqi.Webdiyer.PageChangedEventArgs e)
    {

        pagerNav.CurrentPageIndex = e.NewPageIndex;

        string Sql = @"

select sID,sValue,row from
(
  select *,ROW_NUMBER() OVER (ORDER BY sID asc) AS Row from tInfoParameter ) as temp
where row >={0} and row <={1}

";
        Sql = string.Format(Sql, e.NewPageIndex * 3 -2 , e.NewPageIndex * 3);
        DataSet ds = DataOperation.SelectDataBySql(Sql);

        GridView1.DataSource = ds.Tables[0].DefaultView;
        GridView1.DataBind();

    }
