在WinRT中使用MVVM选择的项目 [英] Selected Items using MVVM in WinRT

问题描述

我正在努力寻找一种方法，以将ListView中的SelectedItems属性绑定到视图模型.

I'm struggling to find a way to bind the SelectedItems property in a ListView to the view model.

以前，我是这样使用的: http://www. codeproject.com/Articles/412417/Managing-Multiple-selection-in-View-Model-NET-Metr (在RTM版本中不再起作用).

Previously I used this: http://www.codeproject.com/Articles/412417/Managing-Multiple-selection-in-View-Model-NET-Metr which no longer works in the RTM release.

非常感谢您的帮助！

先谢谢您了:)

推荐答案

在Visual Studio的输出窗口中:

类型("null")

type ('null')

经过进一步的研究，很明显，任何泛型类都将无法绑定此确切的错误.作为快速解决方案，我只是将类型更改为对象".

After further research it became apparent that any generic class would fail to bind with this exact error. As a quick fix I simply changed the type to "object".
