C＃按钮不触发？ [英] C# Button Not Firing?
本文介绍了C＃按钮不触发？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有我创建一个控制的codeBhind一个ASP按钮。这里是code：
I have an ASP Button that I am creating in the CodeBhind of a Control. Here is the code:
Button SubmitButton = new Button();
protected override void CreateChildControls()
{
SubmitButton.Text = "Submit";
SubmitButton.Click += new EventHandler(SubmitButton_Click);
}
private void SubmitButton_Click(object sender, EventArgs e)
{
CustomTabs.CreateNewTab();
}
Click事件将不火，虽然。它看起来像它回传和嗟事件。任何想法？
The Click event won't fire, though. It appears like it does a postback and never hits the event. Any ideas?
推荐答案
所以，你有没有解释的一些方法，但在添加提交按钮来的页面？某处应该是：
So you have some methods that are not explained, but are you adding the SubmitButton to the page? Somewhere should be:
SomeServerControl.Controls.Add(SubmitButton);
对我来说，以下工作（显然改变命名空间）：
The following works for me (Obviously change namespace):
ASPX
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="VS2010WEBFORMS.WebForm1" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
</form>
</body>
</html>
ASPX.CS
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace VS2010WEBFORMS
{
public partial class WebForm1 : System.Web.UI.Page
{
Button SubmitButton = new Button();
protected void Page_Load(object sender, EventArgs e)
{
SubmitButton.Text = "Submit";
SubmitButton.Click += new EventHandler(SubmitButton_Click);
form1.Controls.Add(SubmitButton);
}
private void SubmitButton_Click(object sender, EventArgs e)
{
//Something
}
}
}
