MahApps Metro 上的重复按钮：如何在鼠标悬停时更改背景？

这是我的滑块： 这是我的滑块： <Slider x:Name="videoPlayerSlider" Minimum="0" Maximum="100" HorizontalAlignment="Stretch" VerticalAlignment="Bottom" Thumb.DragStarted="OnSliderDragStarted_Click" Thumb.DragDelta="OnSliderDragDelta_Drag" Thumb.DragCompleted="OnSliderDragCompleted_Click" Value="50" Height="20" Margin="0,0,0,-20"> <Slider.Template> <ControlTemplate TargetType="Slider"> <Grid>

</Style.Triggers> </Style> 当我将鼠标悬停在两个重复按钮上时，无法更改背景颜色： （这是鼠标悬停在右边的）。我想要“红色”而不是默认的蓝色。我需要使用哪个属性？我上面尝试过的似乎没有任何结果。 有什么线索吗？ 我假设您希望两个重复按钮在“鼠标输入”值为 true 时更改边框颜色。我使用了一般样式，没有扩展你的样式，所以请记住这一点。我将发布的内容绝对是多余的，但我希望这能为您澄清很多事情。我只测试了水平滑块，根据您的描述，这是您想要的结果。该代码还包含垂直滑块，但您可以根据需要修改此模板。希望对你有帮助 <Window.Resources> <Style x:Key="RepeatButtonTransparent" TargetType="{x:Type

自定义日期选择器：如何更改图标图像并单击代码隐藏上的文本框打开弹出窗口？
