Wpf 嵌套容器 [英] Wpf nesting containers

问题描述

在窗口控件上，我的主要容器是一个网格.
我的网格有 2 行，一行定义为 50*，另一行定义为 250*.
现在我想添加一个右侧边栏，比如说使用 StackPanel.
我想在 StackPanel 中有一个与 50* 网格行对齐的 ListBox，这样随着窗口高度变大，ListBox 大小也会变大.
我的问题是，当 ListBox 位于 StackPanel 内(嵌套在网格内)时，我是否可以实现这种行为，还是必须将 ListBox 直接放置在网格内?

On a window control, my main container is a grid.
My grid has 2 rows, one row definition is 50*, and the other is 250*.
Now i want to add a right sidebar, lets say with a StackPanel.
I would like to have a ListBox inside the StackPanel that aligns with the 50* grid row, so as the window height gets bigger, the ListBox size will also get bigger.
My question is whether i can achieve this behavior while the ListBox is inside the StackPanel (which is nested inside the grid) or must the ListBox be placed directly inside the grid?

推荐答案

StackPanel 不会垂直拉伸.

如果您必须需要一个包装父容器，请使用 Grid，它将向所有方向扩展(当然，如果您单独保留 Horizo​​ntal- 和 VerticalAlignment ;))

If you must need a wrapping parent container, use a Grid, which will expand in all directions (if you leave the Horizontal- and VerticalAlignment alone of course ;) )

另请查看 MSDN 上的面板概览.
