为什么在这个切换按钮上没有改变IsChecked？
我有以下用于切换按钮的xaml：
<ToggleButton Margin="0,3" Grid.Row="3" Grid.ColumnSpan="2" Command="{Binding DataContext.SelectAllCommand, Mode=OneWay, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}">
<ToggleButton.Style>
<Style TargetType="{x:Type ToggleButton}">
<Setter Property="Content" Value="Select All"/>
<Style.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter Property="Content" Value="Select None"/>
<Setter Property="Command" Value="{Binding DataContext.SelectNoneCommand, Mode=OneWay, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}"/>
</Trigger>
</Style.Triggers>
</Style>
</ToggleButton.Style>
</ToggleButton>
IsChecked

代替（就像你用那样）来打破。<ToggleButton Name="toggleButton" Margin="0,3" Grid.Row="3" Grid.ColumnSpan="2"> <ToggleButton.Style> <Style TargetType="{x:Type ToggleButton}"> <Setter Property="Content" Value="Select All"/> <Setter Property="Command" Value="{Binding DataContext.SelectAllCommand, Mode=OneWay, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}"/> <Style.Triggers> <Trigger Property="IsChecked" Value="True"> <Setter Property="Content" Value="Select None"/> <Setter Property="Command" Value="{Binding DataContext.SelectNoneCommand, Mode=OneWay, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}"/> </Trigger> </Style.Triggers> </Style> </ToggleButton.Style> </ToggleButton>或类似是否设置为进一步向上可视树。 如果你想将你的版本与我的测试应用进行比较，看看哪些不起作用，我在这里上传了它：http：//www.mediafire.com/？ik24ftsfw2wwfwb草票
<ToggleButton Margin="0,3" Grid.Row="3" Grid.ColumnSpan="2" IsThreeState="False" IsChecked="{Binding DataContext.IsSelected, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}"> <ToggleButton.Style> <Style TargetType="{x:Type ToggleButton}"> <Setter Property="Content" Value="Select All"/> <Setter Property="Command" Value="{Binding DataContext.SelectAllCommand, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}"/> <Style.Triggers> <Trigger Property="IsChecked" Value="True"> <Setter Property="Content" Value="Select None"/> </Trigger> </Style.Triggers> </Style> </ToggleButton.Style> </ToggleButton>庞协腿宛炯
并再试一次。
