仅在 Silverlight DataGrid 中突出显示整行 [英] Highlight entire rows only in Silverlight DataGrid

问题描述

当用户点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有自己的特殊焦点.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...

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行，而不是单个字段.

Is it possible to configure a (readonly) DataGrid so that the user can only select or focus on entire rows, not individual fields.

如果这是不可能的，是否有一种优雅的方法可以只选择第一个元素 - 例如在标准的 Windows 打开对话框中，如果您更改为详细信息视图，则每行都有几列(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.

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(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>
                        <ControlTemplate TargetType="local:DataGridRow">
                            <localprimitives:DataGridFrozenGrid Name="Root">
