在MainWindow上,我有一个ItemsControl
我正在添加UserControls
,并且UserControl
还包含一个ItemsControl
,其中包含其他UserControls
。
问题是第二个ItemsControl中的很多项目没有显示,因为它们超出了MainWindow上显示的UserControl的高度。
如何确保第一个ItemsControl中的UserControl始终足够伸展以显示其ItemsControl中的所有UserControl?对于试验和错误,我尝试通过ItemTemplate伸展,但这并没有改变一件事。

答案 0 :(得分:0)
从我上面的评论中添加,结果证明是问题。
您的UserControl明确设置了Height
和Width
,这意味着他们不会自动调整大小/拉伸以适应您想要的子控件。
删除Height
(理想情况下为Width
)应该可以解决问题:
<UserControl x:Class="X.UserControl1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
mc:Ignorable="d" />
<!-- Your Code -->
</UserControl>
