Question

对于我在我的应用程序中使用的所有其他Datagrids正常工作但由于某种原因，这个没有。

我希望我的Datagrid水平滚动条在数据变大时显示，但它只是扩展整个Datagrid。

我只需要显示水平滚动条，这些是我为使其工作所做的一些事情。

<DataGrid x:Name="dgAllocate" VerticalAlignment="Stretch" HorizontalScrollBarVisibility="Auto" ItemsSource="{Binding}" Foreground="white" BorderBrush="Black" CanUserResizeRows="False" ScrollViewer.CanContentScroll="True" RowHeaderWidth="0" RowHeight="25" AutoGenerateColumns="False" TextBlock.TextAlignment="Center" Margin="26,84,687,91" Style="{x:Null}" Background="#FF616972" FontFamily="Malgun Gothic" AlternationCount="2" GridLinesVisibility="None" CanUserAddRows="False" FontSize="10">

可以回顾一下XAML并告诉我我做错了什么。

Answer 1

HorizontalScrollBarVisibility="Auto" 而不是这个尝试 HorizontalScrollBarVisibility="Visible"

Answer 2

你能分享更多的XAML吗？我想知道你的Datagrid是不是包含在子网格中并因此自动扩展，因为它链接到允许自动重新调整大小的网格（或其他东西）（基本上自动填充到窗口，因为它没有被锁定）

水平滚动条不起作用Datagrid
