分页：

1、先把属性AllowPaging设置为true，

2、pagesize为每一页的行数，PageSize="15".

3、OnPageIndexChanging="gridview1_PageIndexChanging"

<asp:GridView ID="gridYearStsDetailed" runat="server" AutoGenerateColumns="False" CssClass="gridview"

                    EmptyDataText="没有数据" Font-Bold="False" Font-Size="Small" Width="300px"

					ShowFooter="True" PageSize="20" AllowPaging="true"

                    OnPageIndexChanging="gridYearStsDetailed_PageIndexChanging">

                    <Columns>

                        <asp:BoundField DataField="" HeaderText=""/>

                        <asp:BoundField DataField="" HeaderText=""/>

                    </Columns>

                </asp:GridView>

 protected void gridview1_PageIndexChanging(object sender, GridViewPageEventArgs e)

        {

            gridview1.PageIndex = e.NewPageIndex;

            gridview1.DataBind();

       }

		protected void Page_Load(object sender, EventArgs e)

        {

            if (!IsPostBack)

            {

                if (UserInfo.Username.ToLower() == "ykj")

                    lblPageName.Visible = true;
