Introdução

Cimbalino Windows Phone Toolkit é um conjunto de itens uteis e poderosos para ajudar na implementação de aplicações Windows Phone. Projeto base do toolkit contendo serviços para implementação do padrão de MVVM, conversores, classes auxiliares, métodos de extensões;

Cimbalino.Phone.Toolkit.Background - Projeto do toolkit contendo serviços para implementação do padrão de MVVM compatível com “background agents”.

Contruindo o exemplo

O código fonte pode ser obtido em Exemplo ApplicationManifestService (github).

Os pacotes estão disponíveis em Nuget Package Manager (para ambos os "targets") e podem ser instalados, para mais detalhes consultar: Como instalar os pacotes Cimbalino Windows Phone Toolkit. O exemplo deste artigo usa MVVM Light para ajudar na implementação do padrão MVVM, para mais detalhes consultar:

Registando serviços

Devemos começar por registar cada serviço no ViewModelLocator, como podemos ver de seguida:

    /// This class contains static references to all the view models in the
/// application and provides an entry point for the bindings.
public class ViewModelLocator
{
/// Initializes a new instance of the ViewModelLocator class.
public ViewModelLocator()
{
ServiceLocator.SetLocatorProvider(() => SimpleIoc.Default);
 
if (!SimpleIoc.Default.IsRegistered<IApplicationManifestService>())
{
SimpleIoc.Default.Register<IApplicationManifestService, ApplicationManifestService>();
}
SimpleIoc.Default.Register<MainViewModel>();
}
 
public MainViewModel MainViewModel
{
get
{
return ServiceLocator.Current.GetInstance<MainViewModel>();
}
}
 
public static void Cleanup()
{
// TODO Clear the ViewModels
}
}

Implementando a ViewModel

Em seguinda devemos implementar o MainViewModel, como podemos ver de seguida:

    /// This class contains properties that the main View can data bind to.
public class MainViewModel : ViewModelBase
{
/// The public application url.
private readonly string _appUrl;
 
/// The application manifest.
private readonly ApplicationManifest _applicationManifest;
 
/// Initializes a new instance of the application Manifest Service.
public MainViewModel(IApplicationManifestService applicationManifestService)
{
_applicationManifest = applicationManifestService.GetApplicationManifest();
_appUrl = string.Concat("http://windowsphone.com/s?appid=", _applicationManifest.App.ProductId);
}
 
/// Gets the title.
public string Title
{
get
{
return _applicationManifest.App.Title;
}
}
 
/// Gets the author.
public string Author
{
get
{
return _applicationManifest.App.Author;
}
}
 
/// Gets the version.
public string Version
{
get
{
return _applicationManifest.App.Version;
}
}
 
/// Gets the description.
public string Description
{
get
{
return _applicationManifest.App.Description;
}
}
 
/// Gets the product ID.
public string ProductID
{
get
{
return _applicationManifest.App.ProductId;
}
}
 
/// Gets the publisher.
public string Publisher
{
get
{
return _applicationManifest.App.Publisher;
}
}
 
/// Gets the capabilities.
public IList Capabilities
{
get
{
return _applicationManifest.App.Capabilities.ToList();
}
}
}

Implementando a View

Para conetar a view model com a página devemos adicionar a ViewModelLocator no App.xaml:

<vm:ViewModelLocator x:Key="Locator" d:IsDataSource="True"  />

e adicionar o binding na página principal:

 DataContext="{Binding MainViewModel, 
Source={StaticResource Locator}}"

A MainPage.xaml será algo do género:

<phone:PhoneApplicationPage x:Class="CimbalinoSample.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"
xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone"
DataContext="{Binding MainViewModel,
Source={StaticResource Locator}}"

FontFamily="{StaticResource PhoneFontFamilyNormal}"
FontSize="{StaticResource PhoneFontSizeNormal}"
Foreground="{StaticResource PhoneForegroundBrush}"
Orientation="Portrait"
SupportedOrientations="Portrait"
shell:SystemTray.IsVisible="True"
mc:Ignorable="d">
 
<!-- LayoutRoot is the root grid where all page content is placed -->
<Grid x:Name="LayoutRoot" Background="Transparent">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
 
<!-- TitlePanel contains the name of the application and page title -->
<StackPanel x:Name="TitlePanel"
Grid.Row="0"
Margin="12,17,0,28">
<TextBlock Margin="12,0"
Style="{StaticResource PhoneTextTitle2Style}"
Text="Cimbalino Sample" />
</StackPanel>
 
<!-- ContentPanel - place additional content here -->
<Grid x:Name="ContentPanel"
Grid.Row="1"
Margin="12,0,12,0" >
<TextBlock TextWrapping="Wrap"
VerticalAlignment="Top" Height="50">
Title: <Run Text="{Binding Title}"/>
</TextBlock>
<TextBlock TextWrapping="Wrap"
VerticalAlignment="Top" Margin="0,50,0,0">

</TextBlock>
<TextBlock TextWrapping="Wrap"
VerticalAlignment="Top" Margin="0,100,0,0">

</TextBlock>
<TextBlock TextWrapping="Wrap"
VerticalAlignment="Top" Margin="0,150,0,0">

</TextBlock>
<TextBlock TextWrapping="Wrap"
VerticalAlignment="Top" Margin="0,300,0,0">

</TextBlock>
<TextBlock TextWrapping="Wrap"
VerticalAlignment="Top" Margin="0,350,0,0">

</TextBlock>
<TextBlock TextWrapping="Wrap" Text="Capabilities:"
VerticalAlignment="Top" Margin="0,400,0,0"/>
<ListBox DisplayMemberPath="Name" Margin="0,450,0,0"
ItemsSource="{Binding Capabilities}"/>
</Grid>
 
</Grid>
 
</phone:PhoneApplicationPage>
