我想构建一个 WPF 窗口,它使用外部 Grid将屏幕分成 4 个部分。在右下象限,我想嵌入另一个大于网格单元格的 Grid。我一直在寻找添加 ScrollViewer 的方法(或使用 Grid.ScrollViewer 属性),但无论我尝试什么,内部网格都不会适当地调整大小或显示滚动条。
我怀疑这与没有用正确的面板用适当的大小(和调整大小)行为来包装内部网格有关,这将迫使内部网格遵守滚动条,而不是简单地渲染太大(并被另一个剪裁)窗户)。
托管窗口定义如下:
<Window x:Class="GridScrollTest.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:GridScrollTest"
Title="MainWindow" Height="350" Width="525">
<Grid x:Name="OuterGrid">
<Grid.RowDefinitions>
<RowDefinition Height="100" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="100" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<local:SSControl x:Name="Sheet"
Grid.Row="1" Grid.Column="1"
HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Background="Yellow" />
<Canvas Grid.Row="0" Grid.Column="0" Background="LightGreen" />
<Canvas Grid.Row="1" Grid.Column="0" Background="LightBlue" />
<Canvas Grid.Row="0" Grid.Column="1" Background="LightCoral" />
</Grid>
</Window>
和引用的 SSControl:
<UserControl x:Class="GridScrollTest.SSControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
