如何在 WPF 数据网格上启用滚动条/滚动
我有一个位于 Grid 布局容器内的 DataGrid 控件，但我似乎无法在 DataGrid 上实现自动滚动自己去工作。我可以将 DataGrid 包裹在 ScrollViewer 周围，从而添加滚动条，但自动滚动不起作用。
因此，现在，当向 DataGrid 添加新条目时，DataGrid 只是垂直扩展。我希望启用垂直滚动条，以便在添加的项目数量多于原始垂直大小可显示的项目时滚动到 DataGrid 中的项目，而不是整个 DataGrid > 扩大。当然，必须有一种简单的方法来实现这一点。
I've got a DataGrid control that's within a Grid layout container, and I can't seem to get the auto-scroll on the DataGrid itself to work. I can wrap the DataGrid around a ScrollViewer and thus adding the scroll bar, but the auto scrolling doesn't work.
So right now, when new entries are added to the DataGrid, the DataGrid just expands vertically. I'd like to have the vertical scroll bar enabled allowing scrolling to the items in the DataGrid when more items are added than the original vertical size can show, instead of the whole DataGrid expanding. Surely there's got to be an easy way to make that happen.

好吧，弄清楚了这个问题...事实证明我什至不需要将数据网格包裹在 ScrollViewer 周围。我所要做的就是定义数据网格的高度（使用“高度”属性），并且当添加超出高度的项目时会出现数据网格滚动条。显然，当高度未定义时，它是动态的，并随着新项目的添加而垂直扩展。
另一件要添加的事情是，在我的数据网格中，我还为每一行定义了行详细信息，因此当展开多个行详细信息时，将启用滚动，但滚动条行为有点古怪（就像它一样）滚动不平滑），为了使其平滑滚动，修复方法是添加以下 datagrid 属性： ScrollViewer.CanContentScroll="False" （我猜测 datagrid 控件是/继承自 ScrollViewer），然后滚动很流畅，就像正常预期的滚动行为一样。
Okay, got this one figured out ... It turns out I didn't even need to wrap the datagrid around a ScrollViewer after all. All I had to do is define the height for the datagrid (Using the "Height" attribute) and the datagrid scroll bar appears when items are added that go beyond the height. Apparently when the height isn't defined it is dynamic and expands vertically as new items are added.
Another thing to add to this was that in my datagrid, I had a row details defined for each row as well, so when multiple row details were expanded, the scrolling would be enabled, but the scroll bar behavior was a little wacky (Like it wasn't smooth scrolling), and the fix for that to make it smooth scrolling was adding the following datagrid attribute: ScrollViewer.CanContentScroll="False" (I'm guessing the datagrid control is/inherits from a ScrollViewer) and then the scrolling was smooth and like the normal expected scrolling behavior.
