我有一个非常直接的动态生成的 asp 页面。这是我第一次使用动态生成的 asp 控件。该表正确呈现,但是当我单击“查询”按钮时,我无法让事件连接到“OnClick”方法。我收到网页错误“'ButtonClick' 未定义”。为了简洁起见,我已经剥离并简化了代码。
设备状态.aspx
<%@ Page Title="Device Status" Language="C#" MasterPageFile="Secure.master"
'AutoEventWireup="true" CodeFile="DeviceStatus.aspx.cs" Inherits="Devices" %>
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent"></asp:Content>
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<div id="selectDiv" runat="server"></div>
</asp:Content>

button.Click += new System.EventHandler(ButtonClick);
Placeholder1.Controls.Add(button);

Contents = "<form runat=\"server\"><table border=\"1\" >";
Contents += "<tr><th>Select</th><th>Number</th><th>Name</th><th>Status</tr>";
// Repeat for each table row
