在web层添加公共的基类
BaseUser.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using TestWeb.BLL;
using Maticsoft.Common;
namespace TestWeb.Web
{
public class BaseUser:BasePage
{
private int u_id;
private string u_name;
private string u_date;
public string U_date
{
get { return u_date; }
set { u_date = value; }
}
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
// if (Request.Cookies["User"] == null)
// {
// Response.Redirect(Maticsoft.Common.Constant.UserLoginWeb);
// Response.End();
// }
// else
// {
// u_id = Convert.ToInt32(Request.Cookies["User"]["u_id"].ToString());//cookies的值
// u_name =Request.Cookies["User"]["u_name"].ToString();
// }
}
public int U_id
{
get { return u_id; }
set { u_id = value; }
}
public string U_name
{
get { return u_name; }
set { u_name = value; }
}
}
}
基类BasePage.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace TestWeb.Web
{
public class BasePage:System.Web.UI.Page
{
/// <summary>
/// 分页参数设置
/// </summary>
/// <param name="AspNetPager"></param>
public void PageinationBind(Wuqi.Webdiyer.AspNetPager AspNetPager)
{
AspNetPager.UrlPaging = false;//获取或设置是否启用url来传递分页信息
AspNetPager.ShowPageIndexBox = Wuqi.Webdiyer.ShowPageIndexBox.Never;//指定页索引框的显示方式，以便用户输入或从下拉框中选择需要跳转的页索引
AspNetPager.FirstPageText = "首页";
AspNetPager.LastPageText = "尾页";
AspNetPager.NextPageText = "下一页";
AspNetPager.PrevPageText = "上一页";
}
}
}
数据控件直接换成需要的即可
