WPF TreeView垂直滚动条问题 [英] WPF TreeView verticle scrollbar question

问题描述

当我拖动GridSplitter时，保留TreeView的Border会在需要时自动显示水平ScrollBar.
当我的TreeView项超出Borders垂直边界时，是否可以得到类似的verticaly行为?
我很难找到这种行为.默认情况下，一旦降低放置树状视图的原始网格的高度，它就会立即显示垂直滚动条.没问题.

不知何故，你搞砸了.如果您只显示了最少的代码即可重现此问题，则可能会获得更多帮助.在理想情况下，它只会使用XAML，只有一个:Window，一个具有行定义的Grid，一个GridSplitter和一个TreeView.

When I drag my GridSplitter , the Border that holds my TreeView automtically displays a horizontal ScrollBar when needed .
Can I get similar behavior verticaly when my TreeView Items list out of Borders verticle bounds.
I''m having a hard time finding this behavior.

解决方案

In great disbelieve (am I missing something?!), I just tested it. By default, it shows the vertical scroll bar as soon as you decrease the height of the grid raw where the tree view is placed. No problem.

Somehow, you screw it up. It you show possibly minimal code which reproduces the problem, you might get some more help. In perfect case, it would XAML only, with only: one Window, one Grid with row definitions, one GridSplitter and one TreeView.
