Question

我的问题很简单。我试图在按钮上的MouseOver / Hover时设置WPF中按钮的背景。

<Style x:Key="StandardButton" TargetType="Button">
    <Style.Triggers>
        <Trigger Property="IsMouseOver" Value="true">
            <Setter Property="Background" Value="CornflowerBlue" />
        </Trigger>
    </Style.Triggers>
</Style>

当我按下鼠标按钮时，背景颜色会短暂变为CornFlowerBlue，但随后会更改为默认颜色，这些颜色会显示您在按钮上保留一段时间的时间。

当我留在按钮上时，我需要使用什么触发器属性来保持按钮CornFlowerBlue的背景？

非常感谢

这是Button中实现的Button Chrome的默认属性。我已从默认按钮模板中删除了Button chrome并创建了我自己的按钮

当您将鼠标悬停在WPF中的按钮上时，样式触发器是什么？
