摘要:用Linq來結合AspNetPager
先列出datalist的原碼
Class1 cs = new Class1();
protected void Page_Load(object sender, EventArgs e)
{
BindData();
}
protected void AspNetPager1_PageChanged(object sender, EventArgs e)
{
BindData();
}
public void BindData()
{
this.AspNetPager1.RecordCount = cs.getTestCount();
PagedDataSource pds = new PagedDataSource();
pds.DataSource = cs.getTest();
pds.AllowPaging = true;
pds.CurrentPageIndex = this.AspNetPager1.CurrentPageIndex - 1;
pds.PageSize = this.AspNetPager1.PageSize;
this.DataList1.DataSource = pds;
this.DataList1.DataBind();
}
下面則是連結gridview的原碼
前台：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<%@ Register assembly="AspNetPager" namespace="Wuqi.Webdiyer" tagprefix="webdiyer" %>
<!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">

<title>无标题页</title>
</head>
<body>
<form id="form1" runat="server" >
<asp:GridView ID="GridView1" runat="server" AllowPaging="True" PageSize="5">
<PagerSettings Visible="False" />
</asp:GridView>
<webdiyer:AspNetPager ID="AspNetPager2" runat="server"
onpagechanged="AspNetPager2_PageChanged">
</webdiyer:AspNetPager>
</form>
</body>
</html>
后台：
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
ModifyAspNetPager();
gvDataBind(5,1);
}
}
protected void gvDataBind(int pagesize, int pageindex)
{
DataClassesDataContext dc = new DataClassesDataContext();
var aa = (from a in dc.SYS_ProcessOperations
select a).Skip((pageindex-1)*pagesize).Take(pagesize);
GridView1.DataSource = aa;
GridView1.DataBind();
}
protected void ModifyAspNetPager()
{
DataClassesDataContext dc = new DataClassesDataContext();
int bb = (from a in dc.SYS_ProcessOperations
select a).Count();
AspNetPager2.PageSize = GridView1.PageSize;
AspNetPager2.RecordCount = bb;
}
protected void AspNetPager2_PageChanged(object sender, EventArgs e)
{
GridView1.PageIndex = AspNetPager2.CurrentPageIndex;
gvDataBind(GridView1.PageSize,AspNetPager2.CurrentPageIndex);
}
