TabControl不显示 [英] TabControl does not display

问题描述

我有一个非常简单的.net c＃vs 2012应用程序。我正在学习以编程方式使用tabcontrol。我一直在寻找几个小时，找不到我做错了什么。我下面的简单代码没有显示在我的主表单上。我所看到的每个样本和示例都不超过这个，但这并没有显示出来。显然我错过了一些东西。



感谢您的帮助...

I have a pretty simple .net c# vs 2012 app. I'm learning to use the tabcontrol programatically. I've been looking for a few hours and cannot find what I am doing wrong. My simple code below does not show on my main form. Every sample and example that I have looked at does not more than this and yet this does not show. Obviously I am missing something.

Thanks for any help...

private void Form1_Load(object sender, EventArgs e)
{
    TabPage newPage = new TabPage("New Page");
    TabControl tabControl = new System.Windows.Forms.TabControl();
    tabControl.TabPages.Add(newPage);

}

推荐答案

将newPage选项卡添加到tabControl，但是你从不添加tabControl到你的表单。试试这个...

You add the newPage tab to the tabControl, but you never add the tabControl to your form. Try this...

private void Form1_Load(object sender, EventArgs e)
{
    TabPage newPage = new TabPage("New Page");
    TabControl tabControl = new System.Windows.Forms.TabControl();
    tabControl.TabPages.Add(newPage);
    this.Controls.Add(tabControl);
}

谢谢...我看到的演示必须通过设计师添加代码，但无论如何，这确实有效...非常感谢...

Thank you...the demos I saw must have had that code added perhaps via the designer but in any event, that did work...thanks a lot...
