How to change the color of the checked/toggled button programatically
提问by YWah
Let say I've a toggle button which is checked initially and the background color (the color when the button is checked/toggled, NOT the color of the button itself) is blue by default. How to change the background color of the checked/toggled button?
假设我有一个最初选中的切换按钮，默认情况下背景颜色（选中/切换按钮时的颜色，而不是按钮本身的颜色）为蓝色。如何更改选中/切换按钮的背景颜色？
For example:
例如：
if (myCondition == true)
myToggleBtn.Background = System.Windows.Media.Brushes.Red;
The code above is just change the color of the toggle button itself, but I want to change the color checked/toggled button.
上面的代码只是更改切换按钮本身的颜色，但我想更改选中/切换按钮的颜色。
