我有一个简单的按钮，点击时应该在标签中显示文字。但是当我按下按钮时，没有任何反应。我可能会出错的任何想法？
Default.aspx的：
<%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="Default"%>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<asp:Button ID="testbutton" runat="server" Text="Button" OnClick="testbutton_Click" />
<asp:Label ID="testlabel" runat="server"></asp:Label>
</asp:Content>
Default.aspx.cs：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.IO;
using System.Data;

using System.Web.Configuration;
public partial class Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void testbutton_Click(object sender, EventArgs e)
{
testlabel.Text = "You clicked the Testbutton";
}
}

我能够让它发挥作用！
通过删除母版页中的额外表格标签，该按钮现在可以正常工作。
<div id="sb-search" class="sb-search">
<form>
<input class="sb-search-input" placeholder="What are you looking for?" type="search" name="search" id="search">
<input class="sb-search-submit" type="submit" value="">
<span class="sb-icon-search"> </span>
</form>
</div>
