如何在运行时以编程方式向表单添加选项卡? [英] How can i programmatically add a Tab to a form during runtime?

问题描述

我在谷歌上搜索了这个，但仍然无法让它工作.我知道如何使用工具箱添加选项卡.我还阅读了有关如何以编程方式执行此操作的信息，但我仍然不明白.(MSVC# Express 2010)

I googled this and still cant get it to work. I know how to add a tab using the toolbox. I have also read about how to do it programmatically, but i still dont get it. (MSVC# Express 2010)

我有一个简单的项目设置.只是一个带有 TabControl 的 Windows 窗体，我使用设计器添加了一个新的 TabControl 并将该 TabControl 设为公开而不是私有.

I have an easy project set up. Just a windows Form with a TabControl in it, i used the Designer to add a new TabControl and made that TabControl public instead of private.

我写了这段代码a) 访问 Windows 窗体b) 添加标签页.

I wrote this code to a) access the Windows Form b) add a tabpage.

代码编译正常，但运行时不显示Tabpage.

The code compiles just fine, but the Tabpage is not displayed during runtime.

static class Program
{
    [STAThread]
    static void Main()
    {
        Application.SetCompatibleTextRenderingDefault(false);
        Application.EnableVisualStyles();
        Form1 ApplicationMainForm = new Form1();
        Application.Run(ApplicationMainForm); //LABEL B

        ApplicationMainForm.tabControl1.TabPages.Add("MyPage"); //LABEL A
    }
}

如何让表单显示我的标签页?当 A 行和 B 行改变位置时显示我的 TabPage.我是否缺少更新方法，或者在应用程序关闭之前从未调用过 TabPage Add?

How can i get the form to display my Tabpage? My TabPage is displayed when the Lines A and B change position. Am i missing an update method, oder is the TabPage Add never called until the application closes?

推荐答案

Form1.tabControl1.Controls.Add(myNewTabItem);

选项卡控件是选项卡页的集合，因此您可以像向集合中添加任何控件一样添加选项卡页.请注意，选项卡按您添加的顺序显示.

The tab control is a collection of tab pages, so you add tab pages like you add any control to a collection. Note that the tabs show up in the order you add them.
