Question

我在控件的CodeBhind中创建了一个ASP按钮。这是代码：

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();
}

但是，Click事件不会触发。它看起来像是一个回发，从来没有击中事件。有什么想法吗？

因此，您有一些未解释的方法，但是您是否在页面中添加了SubmitButton？某处应该是：

SomeServerControl.Controls.Add(SubmitButton);

以下适用于我（显然更改命名空间）：

<强> 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">

</head>
<body>
    <form id="form1" runat="server">
    </form>
</body>
</html>

<强> 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
        }
    }
}

C＃按钮没有触发？
