DevExpress.XtraGrid.GridControl绑定List笔记.docx

背景最近公司计划按业务domain拆分系统，原有系统客户端用到DevExpress组件，报表展示都是通过GridControl绑定DataTable实现。考虑到和服务端交互数据的性能问题，在项目升级的同时，想把DataTable替换掉。GridControl绑定IListT比较简单，但是在调试主从表效果时，一直没能达到预期效果，子列表的列名一直显示相应类的字段名称。这个问题令人大伤脑筋，调试过程着实花了一番功夫，但是问题的解决方法却让人大跌眼镜。考虑到关于这个问题在网上比较难找，所以这里做了个分享，希望对碰到同样问题的朋友有所帮助。运行效果定义实体类 /// summary /// 学生信息 /// /summary public class StudentEntity { private int stuId; /// summary /// 学号 /// /summary public int StuId { get { return stuId; } set { stuId = value; } } private string stuName; /// summary /// 姓名 /// /summary public string StuName { get { return stuName; } set { stuName = value; } } private ListStuCourseEntity courseList; /// summary /// 所选课程 /// /summary public ListStuCourseEntity CourseList { get { return courseList; } set { courseList = value; } } } /// summary /// 学生选课信息 /// /summary public class StuCourseEntity { private int stuId; /// summary /// 学生编号 /// /summary public int StuId { get { return stuId; } set { stuId = value; } } private int id; /// summary /// 课程编号 /// /summary public int Id { get { return id; } set { id = value; } } private string name; /// summary /// 课程名称 /// /summary public string Name { get { return name; } set { name = value; } } private decimal score; /// summary /// 成绩 /// /summary public decimal Score { get { return score; } set { score = value; } } }构建学员实例 ListStudentEntity studentList = new ListStudentEntity(); studentList.Add(new StudentEntity() { StuId = 101, StuName = 101, CourseList = new ListCourseEntity() { new CourseEntity(){StuId = 101, Id = 201,Name = 语文, Score = 78}, new CourseEntity(){StuId = 101, Id = 202,Name = 数学, Score = 95}, new CourseEntity(){StuId = 101, Id = 203,Name = 外语, Score = 80} } }); studentList.Add(new StudentEntity() { StuId = 102, StuName = 102, CourseList = new ListCourseEntity() { new CourseEntity(){StuId = 102, Id = 201,Name = 语文, Score = 80}, new CourseEntity(){StuId = 102, Id = 202,Name = 数学, Score = 95}, new CourseEntity(){StuId = 102, Id = 203,Name = 外语, Score = 80} } }); studentList.Add(new Stud
