我一直在搞乱数据网格样式几天，我还有一个问题，我似乎无法解决。
我想高举我用鼠标悬停的行的文本。嗯，这似乎是一个简单的任务，但同时我想要行背景和前景的自定义选择颜色。这种组合似乎不可能让我解决。
如果我覆盖datagridrow样式，我可以获得除行上选择样式之外的所有内容。如果我也覆盖datagridcell样式，我可以获得除鼠标悬停前景全行突出显示之外的所有内容。我所拥有的是迄今为止我想出的完整造型。我知道它包含相同任务的重复属性，但我一直在尝试一切。仅缺少完整的行鼠标悬停突出显示 - 仅突出显示悬停的单元格。
你能帮我解决这个微小的细节吗？

将以下xml放在同一解决方案中名为“datagrid.xml”的文件中：
<?xml version="1.0" encoding="utf-8" ?>
<Data>
<Person Firstname="Fred"
Lastname="Flintstone">
</Person>
<Person Firstname="Barney"
Lastname="Rubble">
</Person>
<Person Firstname="Joe"
Lastname="Rockhead">
</Person>
</Data>
谢谢...

好的 - 我最初的问题是，我使用了basestyle，其他所有样式都继承自。这意味着通过样式层次结构多次覆盖Foreground等样式。这件搞糟的事情已经不足以使上述事情变得不可能了。
我的解决方案是删除除DataGrid本身（datagridrowheader，datagridrow，datagridcell）之外的所有数据网格样式的BasedOn属性。仅在DataGrid上设置前景色，您可以在行和单元格样式中覆盖它而没有任何问题。
