JTable事件更新 - 显示错误

Question

我想在jtabele标准事件（例如alert（））中显示错误，但我不知道我必须做什么。代码工作正确。最重要的地方是如果（UpdateOrNot == 1）{}

public void OnUpdated(DictionaryListModel dictionaryListModel) 
     { 
      var listModel = (DictionarySkillListModel)dictionaryListModel; 
      if (dictionaryListModel == null) 
       throw new Exception("Niepoprawny model"); 

      int UpdateOrNot=0; 
      try 
      { 
      if (listModel.IsActiveYN == false) 
      { 
       var list = 
        _skillService.CheckSkillProcedur(listModel.Id, listModel.Description).ToList(); 
       foreach (var procSkillValue in list) 
       { 
        UpdateOrNot = procSkillValue.ExistOrNotExist; 
       } 
       if(UpdateOrNot==1) 
       { 
        //here I would like to past my alert 
       } 
       else 
       { 
        var skill = _skillService.Get(listModel.Id); 
        skill.Name = listModel.Description; 
        skill.IsActive = listModel.IsActiveYN; 
        _skillService.Update(skill); 
       } 
      } 
      } 
      catch (Exception ex) 
      {} 

     }
