一把umbraco的後臺保存驗證

Question

在一把umbraco V7如何顯示上的後臺自定義錯誤的驗證信息保存或發佈到用戶

我曾嘗試以下，但它顯示沒有實際的錯誤「出版工作由第三方插件取消」消息

void ContentService_Saving(IContentService sender, SaveEventArgs<IContent> e) 
{    
    e.Cancel = true;  
    ShowErrorBubble("Error saving item", "Error:duplicate records exists"); 
} 

private static void ShowErrorBubble(string title, string exception) 
{   
    try 
    { 
     umbraco.BasePages.UmbracoEnsuredPage.Current.ClientTools.ShowSpeechBubble(umbraco.BasePages.UmbracoEnsuredPage.speechBubbleIcon.error, title, exception); 

    } 

    catch (Exception ex) 
    { 
      //do nothing at the moment, forums suggest we cannot send an error message 
    } 

}

這就是你使用的是舊片段。無論如何，它從來沒有正常工作。試試這個代碼：

 
void ContentService_Saving(IContentService sender, SaveEventArgs e) 
{      
    ShowErrorBubble(e, "Error saving item", "Error:duplicate records exists"); 

} 

private static void ShowErrorBubble(SaveEventArgs e, string title, string text) 
{   
    try 
    { 
     e.Messages.Add(new Umbraco.Core.Events.EventMessage(title, text, Umbraco.Core.Events.EventMessageType.Warning)); 

     e.Cancel = true; 
    } 

    catch (Exception ex) 
    { 
      //do nothing at the moment, forums suggest we cannot send an error message 
    } 

}
