在我的代码中我想设置一个带有.mdb数据库(oleDb)值的标签,当用户注册为管理员时,我将contentEditable = true属性添加到我希望他能够编辑的部分。当他完成后,他会点击一个“保存”按钮,后面的代码会将新值更新到数据库中 这是代码:(Admin.LogIn(,);如果用户注册为管理员,则返回true)
<%@ Page Title="" Language="C#" MasterPageFile="~/BenOptic.master" AutoEventWireup="true" CodeFile="ben_info.aspx.cs" Inherits="ben_info" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<h1 align="center" id="ben_info_header" runat="server">
</h1>
<h3 align="center" id="ben_info_subheader" runat="server">
</h3>
<p id="ben_info_main_text" runat="server">
</p>
<form id="Form1" action='' method='post' runat='server'><asp:Button id='SaveChanges' Text='שמור' OnClick='saveChanges_Click' runat='server' /></form>
</asp:Content>

foreach (DataRow setting in config.Rows)
