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IList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 / / 学生信息 / public class StudentEntity private int stuId; / / 学号 / public int StuId get return stuId; set stuId = value; private string stuName; / / 姓名 / public string StuName get return stuName; set stuName = value; private List courseList; / / 所选课程 / public List CourseList get return courseList; set courseList = value; / / 学生选课信息 / public class StuCourseEntity private int stuId; / / 学生编号 / public int StuId get return stuId; set stuId = value; private int id; / / 课程编号 / public int Id get return id; set id = value; private string name; / / 课程名称 / public string Name get return name; set name = value; private decimal score; / / 成绩 / public decimal Score get return score; set score = value; 构建学员实例 List studentList = new List(); studentList.Add(new StudentEntity() StuId = 101, StuName = 101, CourseList = new List() 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 List() 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 StudentEntity() StuId = 103, StuName = 103, CourseList = new List() new CourseEntity()StuId = 103, Id = 201,Name = 语文, Score = 90, new CourseEntity()StuId = 103, Id = 202,Name = 数学, Score = 95, new CourseEntity()StuId = 103, Id = 203,Name = 外语, Score = 80 );绑定List到GridControl gcMain.DataSource = studentList;GridControl设置注：这里的LevelName的设置是关键，一定要和Student类的Course
