[C1] C1FlexGrid 排除非绑定列的验证效果

一、前言

前提是 C1FlexGrid 中存在数据绑定列和自定义列（非数据绑定列），此时如果该行编辑后出现排他错误，自定义列也会出现验证结果的红色边框：

但是自定义列如果只是一些按钮操作，提示说明什么的，与前面绑定的数据并无关系，不想参与到前面的排他错误提示，也就是不想要这个红色边框，该如何处理？

二、实现

  1 using System.Collections.ObjectModel;
  2 using System.ComponentModel;
  3 
  4 namespace Validation
  5 {
  6     public class DataObject : IDataErrorInfo
  7     {
  8         public string Name { get; set; }
  9         public int Age { get; set; }
 10         public string Sex { get; set; }
 11         public string UpdateErrorMessage { get; set; }
 12 
 13         // property-level
 14         public string this[string propertyName]
 15         {
 16             get
 17             {
 18                 if (!string.IsNullOrEmpty(UpdateErrorMessage))
 19                 {
 20                     return UpdateErrorMessage;
 21                 }
 22                 if (propertyName == "Name" && string.IsNullOrWhiteSpace(Name))
 23                 {
 24                     return "Name is invalid!";
 25                 }
 26 
 27                 return string.Empty;
 28             }
 29         }
 30 
 31         // item-level
 32         string IDataErrorInfo.Error
 33         {
 34             get
 35             {
 36                 if (!string.IsNullOrEmpty(UpdateErrorMessage))
 37                 {
 38                     return UpdateErrorMessage;
 39                 }

 44 
 45 
 46         // 初始化数据源
 47         public static ObservableCollection<DataObject> InitDataSource()
 48         {
 49             ObservableCollection<DataObject> itemSource = new ObservableCollection<DataObject>();
 50             itemSource.Add(new DataObject() {
 51                 Name = "aa",
 52                 Age = 11,
 53                 Sex = "男" });
 54             itemSource.Add(new DataObject() {
 55                 Name = "vv",
 56                 Age = 15,
 57                 Sex = "男" });
 58             itemSource.Add(new DataObject() {
 59                 Name = "aa",
 60                 Age = 11,
 61                 Sex = "男" });
 62             itemSource.Add(new DataObject() {
 63                 Name = "aa",
 64                 Age = 11,
 65                 Sex = "男" });
 66             itemSource.Add(new DataObject() {
 67                 Name = "aa",
 68                 Age = 11,
 69                 Sex = "男" });
 70             itemSource.Add(new DataObject() {
