C# 如何删除WPF数据网格底部的不可用空间？

在这里，在顶部可以，但当我滚动到末尾时，就不好了：

我可以看出这是因为这个属性：HorizontalScrollBarVisibility，但无论我将其设置为什么，它都会占用空间。我希望它完全消失

如果我让窗口足够长以显示所有项目，它就消失了，这让我认为是垂直滚动条占用了空间，从而使datagrid显示垂直滚动条空间

哦，好吧，从你的评论来看，你好像想让窗口自动调整大小以适应内容，对吗？默认情况下，WPF windows不会这样做，但您可以通过以下方式启用它：

<Window
    ...etc....
    SizeToContent="Width">

您的代码没有导致它出现在我的计算机上，这一定是由于恶意模板或项目中未包含的其他内容造成的。所以您没有看到水平滚动条？没有，一点也没有。我必须删除您对转换器的使用，因为您尚未发布该转换器的源代码，而我绑定到的ItemsSource是一个

字符串[]

（尽管我怀疑这会导致类似的情况）。如果你想发布一篇文章，我很乐意再看一看，但你的项目中似乎有其他东西导致了这一点，而你没有包括在内。事实上，请稍等……你的内容似乎一直延伸到列表控件的右边缘（可能超出了列表控件），在这种情况下，它的可见性是正常的。你到底想做什么，夹紧内容使滚动条不出现？是的，基本上调整窗口大小使其适合宽度。我将发布显示窗口顶部和底部的更新图像，因为当我在顶部时，我看不到水平滚动条。
