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
作者：互联网
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
