我尝试在我的类中IsSelected使用IsSelected字段简单地数据绑定属性.但是在我更改代码中的值之后,它不会更改属性,也不会ListBoxItem更改字段值.

XAML:

<FlipView ItemsSource="{Binding Source={StaticResource itemsViewSource}}" ... >
    <FlipView.ItemTemplate>
        <DataTemplate>
            <UserControl Loaded="StartLayoutUpdates" 
                Unloaded="StopLayoutUpdates">
                <!-- other controls -->
                <ListBox Grid.Row="1" Grid.ColumnSpan="3"
                    SelectionMode="Multiple" VerticalAlignment="Center" 
                    ItemsSource="{Binding Answers}">
                    <ListBox.Resources>
                        <local:LogicToText x:Key="logToText" />
                    </ListBox.Resources>

                     <!-- bind IsSelected only in one way from 
                         code to content --> 
                     <ItemsControl.ItemTemplate>
                        <DataTemplate>
                            <ListBoxItem 
                              IsSelected="{Binding IsSelected, Mode=TwoWay, Converter={StaticResource logToText}}" 
                              Content="{Binding IsSelected, Mode=TwoWay, Converter={StaticResource logToText}}">

                            </ListBoxItem>

                        </DataTemplate>
                    </ItemsControl.ItemTemplate>


                    <!-- not working at all
                    <ListBox.Resources>
                        <Style TargetType="ListBoxItem">
                            <Setter Property="IsSelected" 
                                Value="{Binding IsSelected, Mode=TwoWay}"/>
                            <Setter Property="Content" 
                                Value="{Binding IsSelected, …
