如何从网格的第二行开始包装文本块？

Question

我在一个网格中有 2 行。在第一行我有 5 列，在每一列我都有一个文本块。在第二行，我有一个分隔线。 我可以包装最后一个文本块，以便它应该从网格的第二行开始吗？ 目前这是我的 xaml 代码。

<Grid>
       <Grid.RowDefinitions>
           <RowDefinition/>
           <RowDefinition/>
       </Grid.RowDefinitions>
       <Grid.ColumnDefinitions>
            <ColumnDefinition Width="Auto"/>
            <ColumnDefinition Width="Auto"/>
            <ColumnDefinition Width="Auto"/>
            <ColumnDefinition Width="Auto"/>
            <ColumnDefinition/>
        </Grid.ColumnDefinitions>

          <TextBlock Text="{Binding FullName}" Grid.Row="0" Grid.Column="0" x:Name="firstName" Visibility="{Binding FullName, Converter={StaticResource NullOrWhiteSpaceConverter}}" TextAlignment="Left"/>
          <TextBlock Text=" | " FontWeight="Bold" Foreground="#008DFC" Grid.Column="1" Grid.Row="0" Margin="0,0,0,0" Visibility="{Binding Visibility,ElementName=firstlevel}" HorizontalAlignment="Left"/>
          <TextBlock Text="{Binding FirstLevelParent}" Grid.Row="0" Margin="10,0,0,0" Visibility="{Binding FirstLevelParent, Converter={StaticResource NullOrWhiteSpaceConverter}}" x:Name="firstlevel" Grid.Column="1" TextAlignment="Left"/>
          <TextBlock Text=" | " Foreground="#008DFC" FontWeight="Bold" Grid.Column="1" Grid.Row="0" Visibility="{Binding Visibility,ElementName=middleName}" Margin="0,0,-10,0" HorizontalAlignment="Right"/>
          <TextBlock Text="{Binding SecondLevelParent}"  Grid.Row="0" Margin="10,0,0,0" Visibility="{Binding SecondLevelParent, Converter={StaticResource NullOrWhiteSpaceConverter}}" x:Name="middleName" Grid.Column="2" TextAlignment="Left"/>
          <TextBlock Text=" | " Foreground="#008DFC" FontWeight="Bold" Grid.Column="2" Grid.Row="0" Visibility="{Binding Visibility,ElementName=lastName}" Margin="0,0,-10,0" HorizontalAlignment="Right"/>
          <TextBlock Text="{Binding ThreeLevelParent}"  Grid.Row="0" Margin="10,0,0,0" x:Name="lastName" Visibility="{Binding ThreeLevelParent, Converter={StaticResource NullOrWhiteSpaceConverter}}" Grid.Column="3" TextAlignment="Left"/>
          <TextBlock Text=" | " Foreground="#008DFC" FontWeight="Bold" Grid.Column="3" Grid.Row="0" Visibility="{Binding Visibility,ElementName=fourlevel}" Margin="0,0,-10,0" HorizontalAlignment="Right"/>
          <TextBlock Text="{Binding FourLevelParent}" TextWrapping="Wrap" Grid.Row="0" Margin="10,0,0,0" x:Name="fourlevel" Visibility="{Binding FourLevelParent, Converter={StaticResource NullOrWhiteSpaceConverter}}" Grid.Column="4" TextAlignment="Left"/>

                <Grid Grid.Row="1" x:Name="deliverypoint" Visibility="Collapsed">
                 <!--<Grid.ColumnDefinitions>
                  <ColumnDefinition Width="Auto"/>
                   </Grid.ColumnDefinitions>-->
               <TextBlock Text="{Binding DeliveryPoint}" x:Name="deliverypointname" TextAlignment="Left" Foreground="Black" FontSize="12"/>
                                    </Grid>
            <!--<TextBlock Text="|" Grid.Column="2" Margin="0,0,-6,0" Visibility="{Binding Visibility,ElementName=lastName}" HorizontalAlignment="Right"/>-->
                                </Grid>
                                <TextBlock TextWrapping="NoWrap" Text="-------------------------------------------------------------------------" Grid.Row="1"/>
                            </Grid>

提前致谢。

我建议您不要使用“Grid.ColumnDefinition”来布局您的 TextBlock。相反，您可以使用 WrapPanel XAML Control 来包装这些 TextBlock。达到最大宽度或高度后，控件会根据方向自动创建行或列。

我做了一个简单的代码示例供大家参考：

<Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition />
        </Grid.RowDefinitions>
        <controls:WrapPanel Orientation="Horizontal" HorizontalSpacing="10">
            <TextBlock Text="FullName"  x:Name="firstName"  TextAlignment="Left"/>
            <TextBlock Text=" | " FontWeight="Bold" Foreground="#008DFC"  HorizontalAlignment="Left"/>
            <TextBlock Text="FirstLevelParent"  x:Name="firstlevel"  TextAlignment="Left"/>
            <TextBlock Text=" | " Foreground="#008DFC" FontWeight="Bold" HorizontalAlignment="Right"/>
            <TextBlock Text="SecondLevelParent"  x:Name="middleName" TextAlignment="Left"/>
            <TextBlock Text=" | " Foreground="#008DFC" FontWeight="Bold"  HorizontalAlignment="Right"/>
            <TextBlock Text="ThreeLevelParent" x:Name="lastName" TextAlignment="Left"/>
            <TextBlock Text=" | " Foreground="#008DFC" FontWeight="Bold" HorizontalAlignment="Right"/>
            <TextBlock Text="FourLevelParentFourLevelParentFourLevelParentFourLevelParentFourLevelParentFourLevelParentFourLevelParent" x:Name="fourlevel" TextAlignment="Left" TextWrapping="Wrap"/>
        </controls:WrapPanel>
        <TextBlock TextWrapping="NoWrap" Text="---------------------------------------------------------------------------------------" VerticalAlignment="Top" Grid.Row="1"/>
</Grid>
