c# - 在 WPF 中禁用包含 groupBox 名称的 groupBox

Question

我有一个名为“groupBox”的组框。我想禁用整个组框，包括组框的名称。我附上图片。我希望它能解决这个问题

<GroupBox Name="groupBox"  Grid.Column="0" Grid.Row="1" Margin="2,0,0,0" Header="GroupBox" IsEnabled="False">
            <Grid Margin="10,0,0,0">
                <Grid.ColumnDefinitions>
                    <ColumnDefinition></ColumnDefinition>

                </Grid.ColumnDefinitions>
                <Grid.RowDefinitions>
                    <RowDefinition Height=".250*"/>
                    <RowDefinition Height=".250*"/>
                </Grid.RowDefinitions>
                <RadioButton Name="RadioBtn1" VerticalAlignment="Center"  ToolTipService.ShowOnDisabled="True" Grid.ColumnSpan="3" Height="14.63">OP1</RadioButton>
                <RadioButton Name="RadioBtn2" Grid.Row="1"  VerticalAlignment="Center"  ToolTipService.ShowOnDisabled="True" Grid.ColumnSpan="3" Height="14.63">OP2</RadioButton>

            </Grid>
        </GroupBox>

我正在使用 IsEnabled="False" 属性。但它只适用于 groupBox 的内容(如果我错了，请纠正我!)现在我希望圆圈区域也应该被禁用。

一个简单的 Trigger 可以在 XAML 中为您执行此操作(无需任何代码):

<GroupBox Name="groupBox" Grid.Column="0" Grid.Row="1" Margin="2,0,0,0" Header="GroupBox" IsEnabled="False">
    <GroupBox.Style>
        <Style>
            <Style.Triggers>
                <Trigger Property="Control.IsEnabled" Value="False">
                    <Setter Property="Control.Foreground" Value ="#FF6D6D6D" />
                </Trigger>
            </Style.Triggers>
        </Style>
    </GroupBox.Style>
    <Grid Margin="10,0,0,0">
        <Grid.ColumnDefinitions>
            <ColumnDefinition />
        </Grid.ColumnDefinitions>
        <Grid.RowDefinitions>
            <RowDefinition Height=".250*"/>
            <RowDefinition Height=".250*"/>
        </Grid.RowDefinitions>
        <RadioButton Name="RadioBtn1" VerticalAlignment="Center"  ToolTipService.ShowOnDisabled="True" Grid.ColumnSpan="3" Height="14.63">OP1</RadioButton>
        <RadioButton Name="RadioBtn2" Grid.Row="1"  VerticalAlignment="Center"  ToolTipService.ShowOnDisabled="True" Grid.ColumnSpan="3" Height="14.63">OP2</RadioButton>
    </Grid>
</GroupBox>
