我想在复选时更改复选框的背景颜色而不是显示图标，但我不知道如何执行此操作。我试图创建一个具有不同背景颜色的新“矩形”，并在VisualState上调用他“Checked”，但它没有用。
我的代码：
<Style TargetType="CheckBox">
<Setter Property="Background" Value="{StaticResource CheckBoxBackgroundBrush}" />
<Setter Property="BorderBrush" Value="{StaticResource CheckBoxBorderBrush}" />
<Setter Property="Foreground" Value="{StaticResource NormalFontBrush}" />
<Setter Property="HorizontalContentAlignment" Value="Left" />
<Setter Property="Padding" Value="6,1,0,0" />
<Setter Property="VerticalContentAlignment" Value="Center" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="CheckBox">

<ColumnDefinition Width="13" />
<ColumnDefinition Width="*" />

你走在正确的轨道上。创建具有所需背景颜色和不透明度0的矩形（或边框）。在“已检查”状态下，将“不透明度”设置为1.或者，将“可见性”设置为“折叠”和“动画”可见性，类似于在“按下”状态下为PressedBorder元素设置动画的方式。
在PressedBorder下
<Border x:Name="CheckedBorder" BorderThickness="1" Margin="1" Background="Green" Visibility="Collapsed" />
在VSM中：
<VisualState x:Name="Pressed">
<Storyboard>
<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="PressedBorder">
<DiscreteObjectKeyFrame KeyTime="0" Value="Visible" />
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
