WPF Scroll a Uniformgrid
提问by BlackCath
I need to display all the files located in a specific path. I have created a user control which contains textblocks for the details of the file (name, size, extension, etc), this control will be the child of the uniform grid.
我需要显示位于特定路径中的所有文件。我创建了一个用户控件，其中包含文件详细信息（名称、大小、扩展名等）的文本块，该控件将是统一网格的子项。
The problem is, if my uniformgrid is 5x5, and I have over 25 files, 26th element does not be shown.
问题是，如果我的 uniformgrid 是 5x5，并且我有超过 25 个文件，则不会显示第 26 个元素。
I'd like to know, is there a way to scroll the content of uniform grid?
我想知道，有没有办法滚动统一网格的内容？
I know I can use a listbox and binding (I'm still reading about it), but I need to add the controls programmatically, 'cause the control has an event, and I'm subscribing to it when a new instance of the usercontrol is created and then added to the child array.
我知道我可以使用列表框和绑定（我仍在阅读它），但是我需要以编程方式添加控件，因为控件有一个事件，并且当用户控件的新实例出现时我正在订阅它被创建，然后添加到子数组中。
I've seen thispost, and I already placed the uniforgrid inside a ItemsControl, but It does not work at all, this is my xaml:
我看过这篇文章，我已经将 uniforgrid 放在 ItemsControl 中，但它根本不起作用，这是我的 xaml：
<ScrollViewer Grid.Column="1" VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Disabled" >
<ItemsControl x:Name="gridArchivos">
<ItemsControl.ItemsPanel >
<ItemsPanelTemplate >
<UniformGrid Columns="5" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>
</ScrollViewer>
According to the post, only cols or rows need to be specified, never both. So, only 5 cols. I don't want hrizontal scrolling, only vertical.
根据帖子，只需要指定 cols 或 rows ，而不是同时指定。所以，只有 5 列。我不想要水平滚动，只想要垂直滚动。
Thanks for your time.
谢谢你的时间。
