我的复选框已绑定到我的属性中：

经过一点工作，以下是解决方案：

<Style x:Key="CustomProgressBar" TargetType="ProgressBar">
   <Style.Triggers>
      <DataTrigger Value="True" Binding="{Binding Path=IsChecked}">
         <Setter Property="Background" Value="Red"/>
      </DataTrigger>
      <DataTrigger Value="False" Binding="{Binding Path=IsChecked}">
          <Setter Property="Background" Value="Yellow"/>
      </DataTrigger>
    </Style.Triggers>
    <Setter Property="Template" >
        <Setter.Value>
            <ControlTemplate TargetType="ProgressBar">
                <Border BorderBrush="{DynamicResource ProgressBorderBrushColor}" BorderThickness="0" Background="{DynamicResource ProgressBackgroundColor}" CornerRadius="0" Padding="0">
                    <Grid x:Name="PART_Track">
                        <Rectangle x:Name="PART_Indicator" HorizontalAlignment="Left">
                            <Rectangle.Style>
                                <Style TargetType="Rectangle">
                                    <Setter Property="Fill" Value="{Binding}"/>
                                </Style>
                            </Rectangle.Style>
                        </Rectangle>
                    </Grid>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

如果将复选框的IsCheckedProperty绑定到viewmodel中的布尔值，则可以将datatrigger设置为绑定到该属性，即：checbox->isChecked->viewmodel.isChecked->DatTriggerן我不知道如何在datatrigger中实现它，我可以有一个简单的代码示例吗？在我的复选框中，我有一个：isChecked={Binding Path=IsChecked}我不明白。如果你有一个列表视图，有几个项目，你应该有几个复选框？在这种情况下，你有一个viewmodel来处理你有这个IsChecked属性的单个listviewItem吗？是的，请看我的编辑，目前这只适用于红色，当IsChecked为true时
