LINQ+GridView+AspNetPager 实现分页

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">
<head runat="server">
<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);
}
