[wp7] Command를 Behind에서 사용하자

xaml 상단에 이렇게 datacontext를 연결하고

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

<phone:PhoneApplicationPage

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"

    xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone"

    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

    xmlns:uc="clr-namespace:HugeFlow.FortuneCoins.Controls"

    xmlns:wp="clr-namespace:HugeFlow.Phone.Controls;assembly=HugeFlow.Phone.Controls"

    xmlns:Custom="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity" xmlns:HugeFlow_CommandPattern_Interactivity="clr-namespace:HugeFlow.CommandPattern.Interactivity;assembly=HugeFlow.MVVM" 

    x:Class="HugeFlow.FortuneCoins.Views.BookView"

    FontFamily="{StaticResource PhoneFontFamilyNormal}"

    FontSize="{StaticResource PhoneFontSizeNormal}"

    Foreground="{StaticResource PhoneForegroundBrush}"

    SupportedOrientations="Portrait" Orientation="Portrait"

    mc:Ignorable="d" d:DesignHeight="768" d:DesignWidth="480"    

    shell:SystemTray.IsVisible="False" DataContext="{Binding BookViewModel, Source={StaticResource Locator}}">

behind에서 datacontext를 연결한후

private LocationPermissionViewModel _viewModel;

     public LocationPermissionView()

     {

         InitializeComponent();

         _viewModel = this.DataContext as LocationPermissionViewModel;

     }

그리고 커맨드를 사용할 버튼 이벤트에 이렇게

private void NoButton_Click(object sender, RoutedEventArgs e)
      {
          _viewModel.NoButtonClickCommand.Execute(null);
      }
