问题描述

我正在使用VS2010，并在运行时创建了一个按钮.但是，每当我单击运行时按钮(btnHello)时，都会调用OnClickMeClicked事件.有人可以告诉我为什么吗?以及如何触发内部事件?这是代码:-

I am using VS2010 and have created a button at runtime. But whenever I click on the runtime button (btnHello), the OnClickMeClicked event gets called. Can anybody tell me why ? And how to fire the inner event? Here is the code:-

public void OnClickMeClicked(object sender, EventArgs ea)
        {
            Response.Write("You Clicked My Button!");
            Button btnHello = new Button();
            btnHello.Text = "Hello";
            Page.Form.Controls.Add(btnHello);
            btnHello.Visible = true;
            btnHello.Click +=
                delegate
                {
                    Response.Write("i am newbutton x");
                };
        }

问候.

推荐答案

您无法在那样的运行时创建按钮，每次触发Page_Load事件时，在运行时创建的按钮都会消失，解决方案是:您必须将已创建的按钮列表存储到List<>中.然后在页面"为加载"时，呈现List<>的按钮:)

You can''t created a button at runtime like that, everytime the Page_Load event fired, your button created at runtime will disappear, the solution is: you must be store a list of button you have been created into a List<> and then when the Page is Load, you render the List<> of Button :)
