推荐答案

您是说要在按下鼠标左键时更改颜色，还是在单击鼠标后永久更改颜色?

对于第一种选择，您需要添加一个触发器(在XAML中)，该触发器在按下按钮时会更改颜色.在第二个步骤中，可以将按钮的Background属性绑定到单击按钮时设置的形式的属性.为了使绑定生效，您可能必须从INotifyPropertyChanged派生表单.

Do you mean change color while the left mouse button is down, or change color permenantly after it''s clicked?

For the first choice, you need to add a trigger (in your XAML) that changes the color when the button is pressed. In the second, you could bind the button''s Background property to a property in the form that''s set when the button is clicked. You probably have to derive your form from INotifyPropertyChanged in order to get that binding to work.
