单击CancelBtn取消更改

问题描述

我的程序自定义属性网格中，所有属性都可以从viewModel绑定。在这个属性网格中还有2个按钮--SaveBtn和EditBtn。 用户编辑属性网格中的属性。单击SaveBtn时，所有属性都必须保存在数据库中。如果用户想要编辑属性，则单击EditBtn，然后在将属性保存到数据库（单击SaveBtn）之前，应该出现新窗口，其中用户选择修改属性的原因。在该窗口上还有三个按钮 - ExitWithSavingToDatabase，ExitWithoutSavingToDatabase和Cancel。



如果用户选择取消，则应取消所有更改。但是viewModel中的属性已经有了新值。 我的问题是 - 如何将属性重置为旧值？ 我正在考虑从数据库重新加载属性，但是如果有更好的解决方案，我可以在不使用数据库的情况下完成它？

解决方案

I have in my program custom property grid, where all properties are bindable from viewModel. In this property grid there are also 2 buttons - SaveBtn and EditBtn. User edit properties in property grid. When SaveBtn is clicked, all properties must be saved in a database. If user wants to edit properties, he clicks EditBtn and then before saving properties to database(SaveBtn is clicked), should appear new window, where user chooses a reason of modification of a properties. On that window there are also three buttons - ExitWithSavingToDatabase, ExitWithoutSavingToDatabase and Cancel.

If user chooses Cancel, all changes should be canceled. But properties in viewModel already have new values. My question is - how can I reset properties to old values??? I was thinking of reloading properties from database, but if there is a better solution, where I can do it without using database?
