如何改变点击任何一个按钮的背景颜色？

Question

我有3个按钮。我创建了一个用于所有三个按钮的样式，以显示MouseOver和Pressed状态。我需要逻辑来指示哪个按钮被选中/点击。如果按钮被点击，那么背景颜色应该保持为按下状态，而其他两个按钮应该被重置为背景颜色以作为正常状态。以下是我的代码。我想知道是否有可能在XAML中实现所有功能，或者如何在代码中实现它？谢谢，我提前。

给每个单选按钮相同的组名，你会得到你所需要的功能。而不是

Answer 2

切换按钮？创建一个由两个按钮组成的切换按钮用户控件。一开始隐藏。当您单击可见的人物时，隐藏它并显示隐藏的人物。然后，您还可以在OnClick事件中隐藏/显示其他按钮。

Answer 3

你可以改变它使用“IsFocused” PROPERT，“IsPressed”
