前台设计：
代码如下:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="paging.aspx.cs" Inherits="五二一练习.paging" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script src="js/Jquery1.7.js" type="text/javascript"></script>
<script type="text/javascript">
$(function () {
$('#txtPagination').focus(function () {
$(this).val("");
})
})
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
Height="336px" Width="685px">
<Columns>
<asp:BoundField DataField="Id" HeaderText="编号" />
<asp:BoundField DataField="NewsTitle" HeaderText="标题" />
<asp:BoundField DataField="NewsContent" HeaderText="内容" />
<asp:BoundField DataField="CreateTime"
DataFormatString="{0:yyyy-MM-dd hh:mm:ss}" HeaderText="发布时间" />
</Columns>
</asp:GridView>
<asp:LinkButton ID="btnFirst" runat="server" onclick="btnFirst_Click">第一页</asp:LinkButton>
<asp:LinkButton
ID="btnPre" runat="server" onclick="btnPre_Click">上一页</asp:LinkButton>
<asp:LinkButton ID="btnNext"
runat="server" onclick="btnNext_Click">下一页</asp:LinkButton>
<asp:LinkButton ID="btnLast" runat="server" onclick="btnLast_Click">最后一页</asp:LinkButton><asp:TextBox
ID="txtPagination" runat="server"></asp:TextBox>
<asp:LinkButton ID="btnSkip" runat="server" onclick="btnSkip_Click">GO</asp:LinkButton>
</div>
</form>
</body>
</html>
首先在数据库创建存储过程
代码如下:
create proc usp_role_GetDateByPageIndex
@pageSize int,
@pageIndex int
as
begin
select * from
(
select *,ROW_NUMBER() over(order by role_id) as rownumber from role) as tbl
where tbl.rownumber between (@pageSize*(@pageIndex-1)+1) and @pageIndex*@pageSize
end
exec usp_role_GetDateByPageIndex 5,3
在项目中添加BLL,DAL,DataAccess,MODEL层
在DAL中写一个方法：
代码如下:
//自己写的方法，分页获取数据列表
public DataTable GetListDataTable(int PageSize, int PageIndex)
{
SqlParameter[] parameters = {
new SqlParameter("@PageSize", SqlDbType.Int),
new SqlParameter("@PageIndex", SqlDbType.Int)
};
parameters[0].Value = PageSize;
parameters[1].Value = PageIndex;
return DbHelperSQL.RunProcedureDataTable("usp_role_GetDateByPageIndex", parameters);
}
在BLL中调用GetListDataTable：
public DataTable GetListDataTable(int pagesize, int pageindex)
{
return dal.GetListDataTable(pagesize, pageindex);
}
