[英]Procedure for creating an MvvmCross Store application for Windows 8.1 from scratch?
Using Visual Studio 2013, I am creating a new Windows Store application for Windows 8.1 based on MvvmCross . 使用Visual Studio 2013,我将基于MvvmCross为Windows 8.1创建新的Windows应用商店应用程序。
I first create my PCL .Core class library with view models according to the instructions in the Core.txt to-do file. 我首先根据Core.txt待办事项文件中的说明创建带有视图模型的PCL .Core类库。
Next, I create my .Store application, now following the instructions in the Windows Store UI.txt to-do file. 接下来,我创建我的.Store应用程序,现在按照Windows Store UI.txt待办事项文件中的说明进行操作。 I do want to use the navigation framework, so I am replacing the
FirstView.xaml
page with a Basic Page FirstView.xaml
. 我确实想使用导航框架,所以我用Basic Page
FirstView.xaml
替换FirstView.xaml
页面。
According to the instructions, the LayoutAwarePage
class should inherit MvxStorePage
but since the LayoutAwarePage.cs
is no longer included in VS2013/8.1 Store projects, I am instead changing my FirstView.xaml
page to be an MvxStorePage
type: 根据说明,
LayoutAwarePage
类应继承MvxStorePage
但由于LayoutAwarePage.cs
不再包含在VS2013 / 8.1 Store项目中,我改为将我的FirstView.xaml
页面更改为MvxStorePage
类型:
<views:MvxStorePage x:Name="pageRoot" x:Class="App.Store.Views.FirstView"
... >
...
</views:MvxStorePage>
With this change, FirstView is displayed when I start the app, but the view-model bindings do not work! 通过此更改,我启动应用程序时会显示FirstView ,但视图模型绑定不起作用! What would be the correct procedure for setting up the MvvmCross view-view model bindings in a Windows Store 8.1 app?
在Windows应用商店8.1应用中设置MvvmCross视图模型绑定的正确步骤是什么?
Seems I forgot one part of the instructions in the Windows Store UI.txt to-do file: 似乎我忘记了Windows Store UI.txt待办事项文件中的一部分说明:
Add a views folder and a view - xaml.cs and .xaml based on BasicPage - this will add 5 files to the Common folder.
添加一个views文件夹和一个视图 - 基于BasicPage的xaml.cs和.xaml - 这将添加5个文件到Common文件夹。
- Change the Common/LayoutAwarePage.cs inheritance to Cirrious.MvvmCross.WindowsStore.Views.MvxStorePage- 将Common / LayoutAwarePage.cs继承更改为Cirrious.MvvmCross.WindowsStore.Views.MvxStorePage
- Change the Common/LayoutAwarePage.cs - remove the OnNavigatedTo and OnNavigatedFrom handlers- 更改Common / LayoutAwarePage.cs - 删除OnNavigatedTo和OnNavigatedFrom处理程序
- Add some content for your Xaml - eg<TextBlock Grid.Row="1" Text="{Binding Hello}"/>
- 为你的Xaml添加一些内容 - 例如
<TextBlock Grid.Row="1" Text="{Binding Hello}"/>
If I remove the OnNavigatedTo
and OnNavigatedFrom
overrides from the FirstView.xaml.cs
file, FirstViewModel
will be correctly bound to FirstView
. 如果我从
FirstView.xaml.cs
文件中删除OnNavigatedTo
和OnNavigatedFrom
覆盖,则FirstViewModel
将正确绑定到FirstView
。
So, as far as I can tell, the instructions for Windows Store apps on Windows 8.1 should be: 所以,据我所知,Windows 8.1上Windows Store应用程序的说明应该是:
<Page>
to <views:MvxStorePage>
. <Page>
更改为<views:MvxStorePage>
。 OnNavigatedTo
and OnNavigatedFrom
overrides. OnNavigatedTo
和OnNavigatedFrom
覆盖。 EDIT Additionally, to avoid view-model mix-ups, it might also be a good idea to remove the DefaultViewModel
property and associated defaultViewModel
field from the .xaml.cs file, and also remove the DataContext
attribute from the <views:MvxStorePage>
tag in the .xaml file, since the relevant DataContext
will anyhow be set by MvvmCross . 编辑此外,为了避免视图模型混淆,从.xaml.cs文件中删除
DefaultViewModel
属性和关联的defaultViewModel
字段也是一个好主意,并且还从<views:MvxStorePage>
标记中删除DataContext
属性在.xaml文件中,因为无论如何都会由MvvmCross设置相关的DataContext
。
