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;


Contruindo o exemplo

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:

Vamos começar!

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

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

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

 /// <summary>
/// This class contains properties that the main View can data bind to.
/// </summary>
public class MainViewModel : ViewModelBase
{
/// <summary>
/// The public application url.
/// </summary>
private readonly string _appUrl;
 
/// <summary>
/// The email compose service.
/// </summary>
private readonly IEmailComposeService _emailComposeService;
 
/// <summary>
/// The message
/// </summary>
private string _message;
 
/// <summary>
/// The subject
/// </summary>
private string _subject;
 
/// <summary>
/// The to
/// </summary>
private string _to;
 
/// <summary>
/// Initializes a new instance of the <see cref="MainViewModel"/> class.
/// </summary>
/// <param name="emailComposeService">
/// The email Compose Service.
/// </param>
public MainViewModel(IEmailComposeService emailComposeService)
{
_emailComposeService = emailComposeService;
 
SendFeedbackCommand = new RelayCommand(SendFeedback);
ShareToMailCommand = new RelayCommand(ShareToMail);
SendCommand =new RelayCommand(Send);
_appUrl = string.Concat("http://windowsphone.com/s?appid=8df00038-1b7a-406b-b33f-37a78b17348c");
}
 
/// <summary>
/// Gets or sets the message.
/// </summary>
/// <value>
/// The message.
/// </value>
public string Message
{
get { return _message; }
set { Set("Message", ref _message, value); }
}
 
/// <summary>
/// Gets the send command.
/// </summary>
/// <value>
/// The send command.
/// </value>
public ICommand SendCommand { get; private set; }
 
/// <summary>
/// Gets the send feedback command.
/// </summary>
public ICommand SendFeedbackCommand { get; private set; }
 
/// <summary>
/// Gets the share to e-mail command.
/// </summary>
public ICommand ShareToMailCommand { get; private set; }
 
/// <summary>
/// Gets or sets the subject.
/// </summary>
/// <value>
/// The subject.
/// </value>
public string Subject
{
get { return _subject; }
set { Set("Subject", ref _subject, value); }
}
 
/// <summary>
/// Gets or sets to.
/// </summary>
/// <value>
/// To.
/// </value>
public string To
{
get { return _to; }
set { Set("To", ref _to, value); }
}
 
/// <summary>
/// Sends mails.
/// </summary>
private void Send()
{
if (!string.IsNullOrEmpty(To) && !string.IsNullOrEmpty(Subject) && !string.IsNullOrEmpty(Message))
{
_emailComposeService.Show(To, Subject, Message);
}
}
 
/// <summary>
/// The send feedback.
/// </summary>
private void SendFeedback()
{
const string to = "saramgsilva@gmail.com";
const string subject = "My Feedback";
var body = "This the body";
_emailComposeService.Show(to, subject, body);
}
 
/// <summary>
/// The share to mail.
/// </summary>
private void ShareToMail()
{
const string Subject = "Cimbalino Toolkit Sample";
var body = string.Concat("This application is amazing, you should try it! See in", _appUrl);
_emailComposeService.Show(Subject, body);
}
}

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"
