WPF ListBox WPF XAML内部的顶部对齐
[英]Top Alignment inside WPF ListBox WPF XAML
问题描述
我在WPF窗口中对齐堆栈面板/网格时出现问题。 关于我在做什么错的任何想法吗？ 当我尝试使列表框内的内容顶部对齐时，似乎出现了这种情况，该列表框使用水平对齐的堆栈面板显示项目。
如果我使用ItemsSource = {Binding BoardMarkerRows}将容纳ListBox的网格的高度设置为1400，则对齐将开始正常工作（但我希望此网格具有自动高度）。
屏幕截图显示对齐：
这是我的XAML

我没有足够的声誉将其发布为评论，所以我将其发布为答案。
我相信您的问题可能出在您的ListBox.ItemTemplate中：
...
<ListBox.ItemTemplate>
<DataTemplate>
<Grid VerticalAlignment="Top">
<ListBox Height="Auto"
ItemsSource="{Binding .BoardMarkerRows}" Margin="5" Width="Auto" HorizontalAlignment="Stretch">
<ListBox.ItemTemplate>
<DataTemplate>
<Grid > // Missing vertical allignment in this grid
<Grid Height="Auto" Background="LightGreen" Width="180" Visibility="{Binding ConverterParameter=ArkleEvent
, Converter={StaticResource BoardMarketRowTypeToVisibilityConverter}}" VerticalAlignment="Top" >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="75"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<!--<TextBlock Text="{Binding RowType}" />-->
<TextBlock Text="{Binding ArkleEvent.Name}" Margin="2" Width="Auto" Height="Auto" FontWeight="Bold" />
<TextBlock Grid.Column="1" HorizontalAlignment="Right" Text="{Binding ArkleEvent.Going}" Margin="2" Width="Auto" Height="Auto" />
</Grid>
