<!--LayoutRoot is the root grid where all page content is placed-->

    <!--TitlePanel contains the name of the application and page title-->
    <!--ContentPanel - place additional content here-->
    <Grid x:Name="ContentPanel" Grid.Row="2" Margin="12,0,12,0">
        <ListBox  Height="Auto" HorizontalAlignment="Left" Margin="-12,0,0,0" x:Name="favShaListBox" VerticalAlignment="Top" Width="Auto" FontFamily="Yu Gothic" FontWeight="Bold" RenderTransformOrigin="0.5,0.5" HorizontalContentAlignment="Stretch" ItemsSource="{Binding}">
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <StackPanel Orientation="Horizontal">
                        <TextBlock Text="{Binding Content}" TextWrapping="Wrap" FontSize="24" FontFamily="Yu Gothic" Width="480" />
                    </StackPanel>
                </DataTemplate>
            </ListBox.ItemTemplate>
            <ListBox.ItemContainerStyle>
                <Style TargetType="ListBoxItem">
                    <Setter Property="Name" Value="{Binding QuoteKey}"/>
                </Style>
            </ListBox.ItemContainerStyle>
        </ListBox>
    </Grid>

当我尝试加载这个xaml页面时，它会抛出一个名为XAML parseException的异常，指向Setter中的属性“Value”，用于为上面的Listbox设置样式。

$ exception {“Set property''抛出异常。[Line：50 Position：49]”} System.Exception {System.Windows.Markup.XamlParseException}

它指向一个应用程序栏项名称“copyQuote”，其中我明确指出样式目标只有ListboxItem。

我认为设置ListboxItem的属性存在问题。

<ListBox.ItemContainerStyle>
                <Style TargetType="ListBoxItem">
                    <Setter Property="Name" Value="{Binding QuoteKey}"/>
                </Style>
</ListBox.ItemContainerStyle>

删除此Setter后尝试。

使用样式设置列表框项目名称
