WPF场景下后台生成DataGrid列的代码:

1. /// <summary>
           /// 通用的出勤表头设置
           /// </summary>
           /// <param name="dgView">DataGrid实例</param>
           /// <param name="dataTable">源数据表</param>
           private void SetDataGridHearedOfAttendance(DataGrid dgView, DataTable dataTable)

               dgView.ItemsSource = dataTable.DefaultView;
               dgView.Columns.Clear();
   
               TBCountMessage.Text = "    从  " + SDate + "  到  " + Edate + "   " +
                   "期间的出勤统计信息为: 正常出勤天数为:  "+rePortDp.NomalAttendancedays +"  天，半天数为:  "+rePortDp.HalfdayAttendancedays +"  个,加班时长为:  "+rePortDp.Workovertime+"  小时";
   
               DataGridTextColumn dategridcolumn = new DataGridTextColumn();
               dategridcolumn.Header = "出勤日期";
               dategridcolumn.Width = 180;
               dategridcolumn.Binding = new Binding("AttendanceDate");
               dategridcolumn.Binding.StringFormat = "yyyy年MM月dd日";
               dgView.Columns.Add(dategridcolumn);
   
               DataGridTextColumn DGTCattendancestatus = new DataGridTextColumn();
               DGTCattendancestatus.Header = "出勤状态";
               DGTCattendancestatus.Width = 120;
               DGTCattendancestatus.Binding = new Binding("AttendanceStatus");
               dgView.Columns.Add(DGTCattendancestatus);

               DataGridTextColumn DGTCworkovertime = new DataGridTextColumn();
               DGTCworkovertime.Header = "加班时长";
               DGTCworkovertime.Width = 105;
               DGTCworkovertime.Binding = new Binding("WorkOfTime");
               DGTCworkovertime.Binding.StringFormat="0.0";
               dgView.Columns.Add(DGTCworkovertime);
   
               DataGridTextColumn DGTCattendanceremark = new DataGridTextColumn();

               SetBtnSaveIsEnable(dgView);
