WP MVVM导航OnNavigatedTO [英] WP MVVM Navigation OnNavigatedTO

问题描述

我开始在我的应用程序中实现MVVM，但遇到了一个问题，即知道用户何时导航到视图.

I am starting to implement MVVM in my application and got an issue of knowing when the user navigated to the view.

要在视图之间导航，我只能使用navigationService.Navigate(...);

To navigate between views, I can just use the navigationService.Navigate(...);

如何查看导航到该视图的时间? 我可以使用事件navigationService.Navigated吗?

How do I check when I navigated to the view? May I use the event navigationService.Navigated?

我是否可以使用页面本身提供的其他类似OnNavigatedTo的方法?

Is there no other method I can use like OnNavigatedTo that the page itself provide?

推荐答案

感谢提供的答案.在我决定创建由少数人创建的导航服务的自定义实现之前，两者在一段时间内都是有用的. 然后，我对Cimbalino工具箱做出了贡献以提出建议，并且该工具箱已在不久前推出.

Thanks for the answers provided. Both were helpful over a period of time until I decided to create a custom implementation of the navigation service that has been created by a few people. I then made a contribution to the Cimbalino toolkit to suggest this and it has been introduced a while back.

我个人认为，这可以最好地解决我的问题.看看那里的导航服务.导航事件几乎解决了我遇到的问题.

I my personal opinion, that solves my issue the best. Have a look at the navigation service in there. The Navigated event pretty much solves my issue I had.

基本上可以归结为这一点(在您的视图模型中):

It basically comes down to this (in your viewmodel):

_navigationService.Navigated += OnNavigated;
