用类的继承关系(重写父类的方法)实现简易后台代码模板

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();
}
}

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Child.aspx.cs" Inherits="WebTest.Child" %>

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;
}
}
