仅在Silverlight DataGrid中突出显示整行

Question

当用户单击数据网格中的一行(或使用键盘)时,该行被选中,但他们点击的特定单元格也被赋予了自己的特殊焦点.这对于数据编辑网格来说很好,但我试图创建更像是一个打开的对话框,显示列表中每个项目的属性,所以......

是否可以配置(只读)DataGrid,以便用户只能选择或关注整个行,而不是单个字段.

如果这是不可能的,是否有一种优雅的方式只选择第一个元素 - 例如在标准的Windows打开对话框中,如果更改为"详细信息"视图,则每行有多个列(文件名,创建日期,大小等) ),但您只能突出显示文件名列中的项目.

这是我的(跛脚)版本,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,因为我是单独绘制单元格并且选中的行是隐藏的.

只需将粘贴的代码添加到DataGrid实例:

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