我有一个注入区域的视图（Itemscontrol）。视图仅占用区域中的空间，具体取决于内容大小。我希望视图能够覆盖整个区域的高度。以下是我的观点代码：

ItemsPanelTemplate的{{1}}是什么？
默认值为ItemsControl，不会自动将其子元素拉伸到允许的最大大小。
您必须在StackPanel中将HorizontalAlignment设置为Stretch，或将ItemsContainerStyle更改为自动延伸其子女的内容。

如何UniformGrid使用ItemsPanelTemplate如此
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<UniformGrid />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
另外，StackPanels的定义只根据存在的内容占用空间，所以说VerticalAlignment="Stretch"之类的东西不会在整个父容器中拉伸StackPanel的内容。

尝试使用Grid作为usercontrol的layoutroot，不要设置宽度和高度。
