单击其他按钮时，取消选中切换按钮

Question

根据描述，我有一个ToggleButton和Button。

切换ToggleButton时会显示Button，未切换时会消失。

我想触发ToggleButton属性IsChecked，并在单击Button时将其设置为false。我知道应该用触发器来完成，但我不知道怎么做。

<ToggleButton x:Name="EditBtn" VerticalAlignment="Top" Focusable="False">
<Button VerticalAlignment="Bottom" Height="24" Width="24" 
Visibility="{Binding ElementName=EditBtn, Path=IsChecked, Converter={StaticResource BooleanToVisibilityConverter}}"
Command="{Binding ElementName=InfoList, Path=DataContext.SaveCommand}" CommandParameter="{Binding}" >
<Button.Style>
<Style TargetType="{x:Type Button}" BasedOn="{StaticResource ButtonTransparentStyle}">
<Style.Triggers>
<!-- Something here? -->
</Style.Triggers>
</Style>
</Button.Style>
</Button>

这里有一个使用StoryBoard:的选项

<Button VerticalAlignment="Bottom" Height="24" Width="24" 
Visibility="{Binding ElementName=EditBtn, Path=IsChecked, Converter={StaticResource BooleanToVisibilityConverter}}"
Command="{Binding ElementName=InfoList, Path=DataContext.SaveCommand}" CommandParameter="{Binding}" >
<Button.Triggers>
<EventTrigger RoutedEvent="Button.Click">
<BeginStoryboard>
<Storyboard>
<BooleanAnimationUsingKeyFrames
Storyboard.TargetName="EditBtn"
Storyboard.TargetProperty="(ToggleButton.IsChecked)">
<DiscreteBooleanKeyFrame
KeyTime="00:00:00"
Value="False"/>
</BooleanAnimationUsingKeyFrames>
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</Button.Triggers>
</Button>

您也可以绑定ToggleButton的IsChecked属性，只需在ViewModel中修改附加的属性(在按钮命令触发的void中(。
