5.2 管理员页面的设计与实现
后台管理是专供管理员使用的界面，登录需要专用的用户名和口令。小区物业管理系统网站后台管理功能强大，所有信息都可以在后台管理程序上进行管理。界面视图如图5.2所示：
图5.2管理员基本信息页面
管理员页面的部分代码为：
public partial class guanliindex : System.Web.UI.Page {
protected void Page_Load(object sender, EventArgs e)
protected void LinkButton2_Click(object sender, EventArgs e) {
Response.Redirect(\ }
protected void LinkButton3_Click(object sender, EventArgs e) {
Response.Redirect(\ }
protected void LinkButton1_Click(object sender, EventArgs e) {
Response.Redirect(\ }
protected void LinkButton7_Click(object sender, EventArgs e) {
Response.Redirect(\ }
protected void LinkButton4_Click(object sender, EventArgs e) {
Response.Redirect(\ }
protected void LinkButton5_Click(object sender, EventArgs e) {
Response.Redirect(\ }
protected void LinkButton6_Click(object sender, EventArgs e) {
Response.Redirect(\ }
protected void ImageButton3_Click(object sender, ImageClickEventArgs e) {
Response.Redirect(\ }
protected void ImageButton4_Click(object sender, ImageClickEventArgs e) {
Response.Redirect(\ }
protected void ImageButton5_Click(object sender, ImageClickEventArgs e) {
Response.Redirect(\ }
protected void ImageButton7_Click(object sender, ImageClickEventArgs e) {
