这是我的(蹩脚)版本，它在所选行上添加黑色背景，在当前行上添加灰色背景.我不得不覆盖样式，因为我正在单独绘制单元格并且隐藏了选定的行.

Here is my (lame) version that adds a black background on the selected row and grey background on the current row. I had to overwrite the styles because I was painting the cells individually and the row selected was hidden.

只需将粘贴的代码添加到您的 DataGrid 实例中:

Just add the pasted code to you DataGrid instance:

        <local:DataGrid.RowStyle>
            <Style TargetType="local:DataGridRow">
                <Setter Property="IsTabStop" Value="False" />
                <Setter Property="Template">
                    <Setter.Value>
