如果由于权限,在Sitecore多列表选择项中禁止[项目未找到]的方法？

Question

我们的Sitecore内容树通常分为全局和本地(或国家/地区)页面,以便为我们的分支机构的客户提供服务.正如您所期望的那样,全球页面显示给我们网站的所有观看者,无论他们的地理位置如何,但我们已在可本地化的全局页面上实现了某些字段,例如横幅广告,精选内容等.

我们已经设置了安全性,因此对于多列表,给定的内容编辑器只能看到他们有权访问的左侧的项目.我们遇到的事情是,其他分支内容编辑器选择的项目显示在多列表的右侧"选定"区域中,如果当前正在查看该项目的内容编辑器没有这些项目的权限,它们显示为[未找到项目].我们有好心的内容编辑错误地双击那些删除它们,没有意识到他们正在删除其他编辑故意放置的内容.使用我们德国内容编辑器的视图查看其外观的屏幕截图如下:

如果有一种方法,使用安全或其他方法,来抑制[项目未找到]消息完全是为了到当前内容编辑器没有权限的项目是什么,我想确定的是.任何有关这种方法的好提示(如果可行的话)都会受到赞赏.

您可以创建自己的Multilist类继承自此类的类Sitecore.Shell.Applications.ContentEditor.MultilistEx和覆盖DoRender()方法.在[Item Not Found]显示文本的位置,检查项目是否存在但用户没有访问权限(通过尝试检索项目SecurityDisabler)并显示正确的消息.

然后你需要去core数据库并注册你的字段类型:

最后将字段类型切换为新创建的类型 - 您的字段将如下所示:

下面的代码是MultilistEx您需要的更改的原始反射代码:

using Sitecore.Diagnostics;

using Sitecore.Resources;
using Sitecore.SecurityModel;
