Question

在我的WPF项目中，我在Grid中有一个ItemsControl，它存在于UserControl（最终是一个Window）中。我希望窗口默认是一定的大小，并希望用户能够扩展窗口（如果他们想要的话）（因此不能强制特定的窗口大小）。

问题是，当ItemsControl被填充时，窗口将调整为最大屏幕大小。这非常令人讨厌，因为我希望它受窗口大小的限制，而不是缩放到内容大小。

我怎样才能做到这一点？

尝试将ScrollViewer的{{1}}绑定到其父Height。例如：

ActualHeight

编辑：实际上，这可能不是你的情况，因为你在视图中有多个控件。

您是否尝试将相应<ScrollViewer Grid.Row="3" Height={Binding ActualHeight, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type Grid}} VerticalScrollBarVisibility="Auto"> <ItemsControl x:Name="Items" Margin="0" Background="{DynamicResource VeryDarkGradientIndented}" /> </ScrollViewer>的{{1}}设置为Height？

RowDefinition

阻止网格扩展以适应内容，同时允许用户调整窗口大小
