如何添加一个窗体加载事件（当前不工作） [英] How to add a form load event (current not working)

问题描述

我在哪里，我想表明，当窗体加载用户控件的Windows窗体。 Unforunately，它没有显示任何东西。我究竟做错了什么？请参考下面code：

I have a windows form where I am trying to show a user control when the form loads. Unforunately, it is not showing anything. What am I doing wrong? Please see code below:

  AdministrationView wel = new AdministrationView();
        public ProgramViwer()
        {
            InitializeComponent();
        }


        private void ProgramViwer_Load(object sender, System.EventArgs e)
        {
            formPanel.Controls.Clear();
            formPanel.Controls.Add(wel);
        }

请注意我说的Load事件基于我在这篇文章中读到：

Please note I added the load event based on what I read in this article:

推荐答案

有三种方法可以做到这一点 - 从表单设计器中，选择的形式，您通常看到的属性列表，只是它上面应该有小闪电符号 - 这说明你的表格的所有事件。在列表中找到的形式加载事件，你应该能够挑选 ProgramViwer_Load 从下拉列表中。

Three ways you can do this - from the form designer, select the form, and where you normally see the list of properties, just above it there should be a little lightning symbol - this shows you all the events of the form. Find the form load event in the list, and you should be able to pick ProgramViwer_Load from the dropdown.

做的第二种方法是通过编程 - 地方（也许构造函数），你需要添加它，是这样的： ProgramViwer.Load + =新的EventHandler（ProgramViwer_Load）;

A second way to do it is programmatically - somewhere (constructor maybe) you'd need to add it, something like: ProgramViwer.Load += new EventHandler(ProgramViwer_Load);

使用设计器（可能是最快的）第三种方式 - 当你创建一个新的形式，双上它是在设计模式中，中间点击。它会为你创建一个Form Load事件，把它挂在，并带您到事件处理程序code。然后，你可以添加两行，你是好去！

A third way using the designer (probably the quickest) - when you create a new form, double click on the middle of it on it in design mode. It'll create a Form load event for you, hook it in, and take you to the event handler code. Then you can just add your two lines and you're good to go!
