推荐答案

正如@Chris 所说，前三项中的任何一项应该起作用，而正如@Phyxx 所说，它并不总是真正起作用.问题是关于属性更改顺序的一些微妙的事情.要解决此问题，您需要让 WPF 在其自己的时间调用您的选项卡选择代码:

As @Chris says, any of the first three things should work and as @Phyxx says, it doesn't always really work. The problem is some subtle thing about the order of property changes. To work around it you need to let the WPF invoke your tab-selection code in its own time:

Dispatcher.BeginInvoke((Action)(() => MyTabControl.SelectedIndex = x));

这与 Phyxx 的计时器所做的一样，但方式稍微不那么极端.

This does just what Phyxx' timer does, but in a slightly less extreme way.
