lightswitch html将本地属性添加到实体集合 [英] lightswitch html add local properties to entity collection

问题描述

嗨

我需要一些帮助.

我有一个浏览数据屏幕，用户可以在其中为我只想使用临时的集合中的每个项目输入一些值，而不必将其保存在数据库中，因此有一种添加方法集合中每个项目的本地属性?

I have a browse data screen where the user can enter some values for each item in a collection that i just want to use temporary, and it doesn't have to get saved in the database, So is there a way to add a local property to each item of a collection?

我也尝试使用常规属性，但是当用户想要关闭屏幕时，它会显示一条消息，指出屏幕上有未保存的更改，所以当用户离开时，有一种方法可以放弃更改屏幕?

Also i try to use a regular property but then when the user wants to close the screen it show up a message that there are unsaved changes on the screen, So is there a way to discard the changes when the user navigates away from the screen? 

请帮忙.

谢谢

推荐答案

添加这样的属性不起作用吗?

When you add a property like this it doesn't work?
