问题描述
当用户单击数据网格中的一行(或使用键盘)时，将选择该行，但是他们单击的特定单元格也具有其自己的特殊焦点.这对于数据编辑网格来说很好，但是我正在尝试创建更类似于打开对话框的工具，该对话框显示列表中每个项目的属性，所以...
When the user clicks on a row in the datagrid (or uses the keyboard), that row is selected, but the specific cell they clicked on is also given its own special focus. This is fine for a data editing grid, but I am trying to create something more like an open dialog that shows properties for each item in the list, so...
是否可以配置(只读)DataGrid，以便用户只能选择或关注整个行，而不能选择单个字段.
Is it possible to configure a (readonly) DataGrid so that the user can only select or focus on entire rows, not individual fields.
如果无法实现，是否有一种优雅的方法可以仅选择第一个元素-例如在标准Windows打开对话框中，如果更改为详细信息"视图，则每一行都有几列(文件名，创建日期，大小等)，但您只能在文件名"列中突出显示项目.
If that is not possible, is there a elegant way of making only the first element selectable - for example in the standard Windows Open dialog, if you change to Details view there are several columns for each row (Filename, Created Date, Size, etc), but you can only highlight items in the filename column.
推荐答案
这是我的(lame)版本，在选定的行上添加黑色背景，在当前行上添加灰色背景.我必须覆盖样式，因为我要分别绘制单元格，并且所选行被隐藏.
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实例中即可:
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>
<ControlTemplate TargetType="local:DataGridRow">
