本文實例演示了DevExpress完成GridControl單位格編纂驗證的辦法，比擬適用的功效，詳細辦法以下：

重要功效代碼以下：

/// <summary>
/// 自界說單位格驗證
/// </summary>
/// <param name="view">GridView</param>
/// <param name="e">BaseContainerValidateEditorEventArgs</param>
/// <param name="fieldNameHandler">拜托</param>
/// <param name="errorHanlder">拜托</param>
/// <param name="errorText">當驗證欠亨過對時刻，毛病提醒信息文字</param>
public static void CustomValidatingEditor(this GridView view, BaseContainerValidateEditorEventArgs e, Predicate<string> fieldNameHandler, Predicate<object> errorHanlder, string errorText)
{
  /*解釋
   *在ValidatingEditor事宜應用
   *eg:
   *string[] workType = new string[4] { "-1", "封閉但不刪除", "啟用", "刪除" };
   *void gvLampConfig_ValidatingEditor(object sender, DevExpress.XtraEditors.Controls.BaseContainerValidateEditorEventArgs e)
   *{
   * GridView _view = sender as GridView;
   * _view.CustomValidatingEditor(e, fieldName => fieldName.Equals("TLampWorkStatus"), value => !workType.Contains<string>(value.ToString()), "若想設置為不修正，請輸出-1便可");
   * }
   */
  if (fieldNameHandler(view.FocusedColumn.FieldName))
  {
 if (errorHanlder(e.Value))
 {
   e.Valid = false;
   e.ErrorText = errorText;
 }
  }
}

代碼應用辦法以下：

string[] workType = new string[4] { "-1", "封閉但不刪除", "啟用", "刪除" };
void gvLampConfig_ValidatingEditor(object sender, DevExpress.XtraEditors.Controls.BaseContainerValidateEditorEventArgs e)
{
  GridView _view = sender as GridView;
  _view.CustomValidatingEditor(e, fieldName => fieldName.Equals("TLampWorkStatus"), value => !workType.Contains<string>(value.ToString()), "若想設置為不修正，請輸出-1便可");
}
