Answer 2

这是generic里的
<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="clr-namespace:WpfApplication1">    <ResourceDictionary.MergedDictionaries>
        
        <ResourceDictionary Source="/WpfApplication1;component/Themes/KDataGrids.xaml" />    </ResourceDictionary.MergedDictionaries>
</ResourceDictionary>标红的部分就是我引用的样式

Answer 3

打开一个DataGrid, 然后右键创建样式副本，看看DataGrid默认的样式；然后再写自己的样式；
