實驗代碼如下：
首先是模板類的抽象，繼承自Page類；
代碼如下:
public class Template : System.Web.UI.Page
{
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
if (!IsPostBack)
{
DataRefresh();
}
}
protected virtual void DataRefresh()
{
}
protected virtual void grid_Init(object sender, EventArgs e)
{
var grid = sender as GridView;
grid.AllowPaging = true;
grid.PageSize = 10;
grid.PagerSettings.Mode = PagerButtons.NumericFirstLast;
}
protected virtual void grid_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
var grid = sender as GridView;
grid.PageIndex = e.NewPageIndex;
DataRefresh();
}
}
然后是一個繼承此模板類的具體實例；
代碼如下:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Child.aspx.cs" Inherits="WebTest.Child" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:GridView ID="grid" runat="server" OnInit="grid_Init" OnPageIndexChanging="grid_PageIndexChanging"></asp:GridView>
</div>
</form>
</body>
</html>
最后就是關鍵的后臺代碼實現，此處假設需要修改grid的每頁顯示數和分頁樣式；
代碼如下:
public partial class Child : Template
{
protected override void DataRefresh()
{
grid.DataSource = new LogDao().GetLogsByYearMonth("2012", "10");
grid.DataBind();
}
protected override void grid_Init(object sender, EventArgs e)
{
base.grid_Init(sender, e);
grid.PagerSettings.Mode = PagerButtons.NextPreviousFirstLast;
grid.PageSize = 15;
}
}
