Question

我有一组按钮，每当单击其中一个按钮而禁用被单击的按钮时，它们就会启用。

<Button DockPanel.Dock="Top" Style="{StaticResource BigGrayButton}" Command="{Binding Path=NavigatePage}" IsEnabled="{Binding Path=EnableButton}"/>
<Button DockPanel.Dock="Top" Style="{StaticResource BigGrayButton}" Command="{Binding Path=NavigatePage}" IsEnabled="{Binding Path=EnableButton}"/>
<Button DockPanel.Dock="Top" Style="{StaticResource BigGrayButton}" Command="{Binding Path=NavigatePage}" IsEnabled="{Binding Path=EnableButton}"/>
<Button DockPanel.Dock="Top" Style="{StaticResource BigGrayButton}" Command="{Binding Path=NavigatePage}" IsEnabled="{Binding Path=EnableButton}"/>

问题是使用上述代码导致在执行命令后将 EnableButton 设置为false时，禁用所有按钮。

正如我所说，为什么不尝试orders.PAID_AT.fillna(method='bfill', inplace=True)？

如果您只想实现此“功能”，这太简单了-甚至不需要涉及MVVM

然后，您可以为每个按钮设置<StackPanel HorizontalAlignment="Center" VerticalAlignment="Center"> <StackPanel.Resources> <SolidColorBrush x:Key="Button.Static.Background" Color="#FFDDDDDD"/> <SolidColorBrush x:Key="Button.Static.Border" Color="#FF707070"/> <SolidColorBrush x:Key="Button.MouseOver.Background" Color="#FFBEE6FD"/> <SolidColorBrush x:Key="Button.MouseOver.Border" Color="#FF3C7FB1"/> <SolidColorBrush x:Key="Button.Pressed.Background" Color="#FFC4E5F6"/> <SolidColorBrush x:Key="Button.Pressed.Border" Color="#FF2C628B"/> <SolidColorBrush x:Key="Button.Disabled.Background" Color="#FFF4F4F4"/> <SolidColorBrush x:Key="Button.Disabled.Border" Color="#FFADB2B5"/> <SolidColorBrush x:Key="Button.Disabled.Foreground" Color="#FF838383"/> <Style x:Key="FocusVisual"> <Setter Property="Control.Template"> <Setter.Value> <ControlTemplate> <Rectangle Margin="2" SnapsToDevicePixels="true" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" StrokeThickness="1" StrokeDashArray="1 2"/> </ControlTemplate> </Setter.Value> </Setter> </Style> <Style x:Key="BaseButtonStyle" TargetType="{x:Type RadioButton}"> <Style.Triggers> <Trigger Property="IsChecked" Value="true"> <Setter Property="IsEnabled" Value="False"/> </Trigger> </Style.Triggers> <Setter Property="FocusVisualStyle" Value="{StaticResource FocusVisual}"/> <Setter Property="Background" Value="{StaticResource Button.Static.Background}"/> <Setter Property="BorderBrush" Value="{StaticResource Button.Static.Border}"/> <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/> <Setter Property="BorderThickness" Value="1"/> <Setter Property="HorizontalContentAlignment" Value="Center"/> <Setter Property="VerticalContentAlignment" Value="Center"/> <Setter Property="Padding" Value="1"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type RadioButton}"> <Border x:Name="border" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" SnapsToDevicePixels="true"> <ContentPresenter x:Name="contentPresenter" Focusable="False" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/> </Border> <ControlTemplate.Triggers>  <Trigger Property="IsMouseOver" Value="true"> <Setter Property="Background" TargetName="border" Value="{StaticResource Button.MouseOver.Background}"/> <Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.MouseOver.Border}"/> </Trigger> <Trigger Property="IsPressed" Value="true"> <Setter Property="Background" TargetName="border" Value="{StaticResource Button.Pressed.Background}"/> <Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.Pressed.Border}"/> </Trigger> <Trigger Property="IsEnabled" Value="false"> <Setter Property="Background" TargetName="border" Value="{StaticResource Button.Disabled.Background}"/> <Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.Disabled.Border}"/> <Setter Property="TextElement.Foreground" TargetName="contentPresenter" Value="{StaticResource Button.Disabled.Foreground}"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style> </StackPanel.Resources> <RadioButton Content="Button1" Style="{StaticResource BaseButtonStyle}"/> <RadioButton Content="Button2" Style="{StaticResource BaseButtonStyle}"/> <RadioButton Content="Button3" Style="{StaticResource BaseButtonStyle}"/> <RadioButton Content="Button4" Style="{StaticResource BaseButtonStyle}"/> </StackPanel>，以告知后端代码按下了哪个按钮。

您无需编写任何复杂的逻辑即可实现此功能。为什么不尝试呢？
