WPF中的复合ViewModel [英] Composite ViewModels in WPF

问题描述

是否可以使视图模型由其他视图模型组成?在实践中这将如何工作?我有在多个视图中重用的数据，并且我有由几组数据组成的视图.因此，我基本上希望建立多对多关系 视图和视图模型之间的联系，而我的有限理解是，视图和视图模型之间的联系是一对多的.

Is it possible to have view model composed of other view models? How would this work in practice? I have data that is reused in several views and I have views that are made up several groups of data. So essentially I would like a many to many relationship between views and view models and my limited understanding is that it is a many to one relationshop between views and view models.

推荐答案

您为模板中所有视图提供的VM，您提到了将哪个视图关联到那里的VM之间的关系，您可以将5个视图设置为1个VM

you can you a VM for all your views in the templet you mention the relation between which view is assosiated to which VM there you can set up 5 views to 1 VM

 

<b;< DataTemplate DataType =" {x:Type vm:SelectListViewModel}"

 <DataTemplate DataType="{x:Type vm:SelectListViewModel}">

        < vw:SelectListView/>

        <vw:SelectListView />

    </DataTemplate>

    </DataTemplate>
