WPF C#以编程方式添加和移动选项卡 [英] WPF C# Programmatically adding and moving tabs

问题描述

我目前正在做一些可能在许多示例中完成的事情.但是经过一番搜索，我什么都找不到.

I'm currently working on something that is probably done in plenty of examples out there. But after some searching I can't find anything.

我正在使用WPF选项卡控件，并且尝试通过单击"+"选项卡(这是最后列出的选项卡)来重新创建一些基本功能(如今在所有Internet浏览器中都可以看到).

I'm working with WPF tab control and I'm trying to recreate some basic functionality (which you see in all internet browsers nowadays) to add a new tab by clicking a '+' tab which is the last listed tab.

我已经有了"+"标签，该标签添加了一个新标签.我的问题是，我想将"+"选项卡移到新选项卡之后(因此再次是结束选项卡)，然后将视图切换到刚创建的新选项卡.

I already have the '+' tab which adds a new tab. My problem is, I want to move the '+' tab after the new tab (so its the end tab again) and switch view to the new tab that has just been created.

我认为:

    void tiNewTab_Add(object sender, EventArgs e)
    {
        int idx = tabControl1.Items.Count;
        tabControl1.SelectedIndex = idx - 1;
        TabItem ti = new TabItemKPI();
        tabControl1.Items.Add(ti);
        tabControl1.Items.MoveCurrentToLast();
    }

...可以工作，但是没有运气:(

...would work but no luck :(

推荐答案

尝试如下操作:

tabControl1.Items.Insert(tabControl1.Items.Count-1,ti); 

之所以这样做，是因为您总是至少有一个TabItem(即+)

This will do because you always have at least one TabItem (the + one)

然后选择倒数第二个

tabControl1.SelectedIndex=tabControl1.Items.Count-2;
