本文主要是介绍Dev中实现给GridControl下的GridView表格修改指定行、列的背景颜色和获取选择行的信息，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

一、实现效果

①修改GridView的标题背景颜色；

②修改选中行的背景颜色；

③修改指定行的背景颜色；

④修改指定列的背景颜色；

⑤修改指定单元格的背景颜色；

⑥获取GridView表格选中行的数据信息；

⑦获取GridView的标题头名称、字段；

⑧修改GridView的标题头名称；

二、实现核心

三、使用方法

3.1、修改背景颜色使用GirdView的【CustomDrawCell】事件

3.2、获取选中行的信息使用GirdView的【FocusedRowChanged】事件
