WrapPanel ListBox没有换行 _没有

学向勤中得，萤窗万卷书。这篇文章主要讲述WrapPanel ListBox没有换行相关的知识，希望能为你提供帮助。
我正在尝试使用此样式创建一个带有Button DataTemplate的WrapPanel ListBox：

< Style x:Key="lbxStyle" TargetType="ListBox"> < Setter Property="Background" Value="https://www.songbingjia.com/android/{StaticResource primaryBrush}"/> < Setter Property="Foreground" Value="https://www.songbingjia.com/android/White"/> < Setter Property="VerticalAlignment" Value="https://www.songbingjia.com/android/Top"/> < Setter Property="VerticalContentAlignment" Value="https://www.songbingjia.com/android/Top"/> < Setter Property="ScrollViewer.CanContentScroll" Value="https://www.songbingjia.com/android/True"/> < Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="https://www.songbingjia.com/android/Hidden"/> < Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="https://www.songbingjia.com/android/Disabled"/> < Setter Property="Margin" Value="https://www.songbingjia.com/android/6"/> < Setter Property="ItemsPanel"> < Setter.Value> < ItemsPanelTemplate> < WrapPanel IsItemsHost="True" Orientation="Horizontal"/> < /ItemsPanelTemplate> < /Setter.Value> < /Setter> < Setter Property="ItemTemplate"> < Setter.Value> < DataTemplate> < Button> < Button.Template> < ControlTemplate TargetType="Button"> < Border HorizontalAlignment="Left" VerticalAlignment="Top" BorderBrush="White" Background="Transparent" BorderThickness="2" Margin="4,2,0,0"> < Border.Triggers> < EventTrigger RoutedEvent="Border.MouseEnter"> < EventTrigger.Actions> < BeginStoryboard> < Storyboard> < ColorAnimation Storyboard.TargetProperty=" (Border.Background). (SolidColorBrush.Color)" From="Transparent" To="{StaticResource accentColorTwo}" Duration="0:0:0.25"/> < /Storyboard> < /BeginStoryboard> < /EventTrigger.Actions> < /EventTrigger> < EventTrigger RoutedEvent="Border.MouseLeave"> < EventTrigger.Actions> < BeginStoryboard> < Storyboard> < ColorAnimation Storyboard.TargetProperty=" (Border.Background). (SolidColorBrush.Color)" From="{StaticResource accentColorTwo}" To="Transparent" Duration="0:0:0.25"/> < /Storyboard> < /BeginStoryboard> < /EventTrigger.Actions> < /EventTrigger> < /Border.Triggers> < ContentPresenter TextBlock.TextAlignment="Center" TextBlock.Foreground="White" TextBlock.FontFamily="SegoeUI" TextBlock.FontSize="14" Content="{Binding}" Name="content"/> < /Border> < /ControlTemplate> < /Button.Template> < /Button> < /DataTemplate> < /Setter.Value> < /Setter> < /Style>

在主窗口中，它引用如下：

< ListBox x:Name="lbxUninspectedPrints" Height="125" Margin="16,0" Style="{StaticResource lbxStyle}" ItemsSource="{Binding UninspectedPrintList}" SelectedValue="https://www.songbingjia.com/android/{ Binding DiePrintNav.SelectedDiePrintString, Mode=OneWayToSource}"/>

但它不想妥善包装。这是一个截图：

答案【WrapPanel ListBox没有换行】所以诀窍是将宽度，高度和对齐设置器移出边框并进入按钮本身。我做了一些其他的更改，但是这个列表框的工作版本发布在下面（请注意，由于绑定问题，我必须将所有内容移出样式并插入ListBox引用内联）。

< ListBox Name="lbxUninspectedPrints" Height="125" Margin="16,0" Background="{StaticResource primaryBrush}" Foreground="White" VerticalAlignment="Top" VerticalContentAlignment="Top" HorizontalContentAlignment="Left" ScrollViewer.CanContentScroll="True" ScrollViewer.VerticalScrollBarVisibility="Hidden" ScrollViewer.HorizontalScrollBarVisibility="Disabled" ItemsSource="{Binding UninspectedPrintList}"> < ListBox.ItemsPanel> < ItemsPanelTemplate> < WrapPanel/> < /ItemsPanelTemplate> < /ListBox.ItemsPanel> < ListBox.ItemTemplate> < DataTemplate> < Button DataContext="{Binding}" Width="44" Height="24" VerticalAlignment="Top" VerticalContentAlignment="Center" HorizontalAlignment="Left" HorizontalContentAlignment="Center" Content="{Binding}" Command="{ Binding DataContext.DiePrintNav.UninspectedPrintSelectedCommand, RelativeSource={RelativeSource AncestorType=ListBox}}" CommandParameter="{Binding RelativeSource={RelativeSource Self}, Path=Content}"> < Button.Template> < ControlTemplate TargetType="Button"> < Border BorderBrush="White" BorderThickness="2" Background="Transparent"> < Border.Triggers> < EventTrigger RoutedEvent="Border.MouseEnter"> < EventTrigger.Actions> < BeginStoryboard> < Storyboard> < ColorAnimation Storyboard.TargetProperty=" (Border.Background).
