MVVM程式分析

1.app.xaml

    <Application.Resources>    <ResourceDictionary>    <ResourceDictionary.MergedDictionaries>                <ResourceDictionary Source="Skins/Generic.xaml" />    </ResourceDictionary.MergedDictionaries>    <language:LocalizedStrings x:Key="LocalizedStrings" />    <local:MvvmViewModelLocator x:Key="Locator" />    </ResourceDictionary>    </Application.Resources>

Locator是用來指明那個xaml的datacontext綁定那個ViewModel。

2.MainPage.xaml

通過以下代碼指定資料繫結。

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

 指定資料顯示模板和觸發命令。

<phone:PhoneApplicationPage.Resources>        <DataTemplate x:Key="TurnstileItemTemplate">            <Grid Background="{StaticResource PhoneAccentBrush}"  Margin="10" Width="150" Height="150">                <StackPanel VerticalAlignment="Center" HorizontalAlignment="Center">                    <Border BorderBrush="Gray">                        <Image Width="62" Height="62"  Source="{Binding IcoUrl}" Stretch="Fill" />                    </Border>                    <TextBlock Text="{Binding MenuName}"                                           Foreground="{StaticResource PhoneContrastBackgroundBrush}"                                           Margin="3"                                           FontSize="24" HorizontalAlignment="Center" VerticalAlignment="Center"/>                </StackPanel>                <i:Interaction.Triggers>                    <i:EventTrigger EventName="MouseLeftButtonDown">                        <cmd:EventToCommand Command="{Binding MainVM.MenuCommand,Source={StaticResource Locator}}"                                             CommandParameter="{Binding Type}"/>                    </i:EventTrigger>                </i:Interaction.Triggers>            </Grid>        </DataTemplate>    </phone:PhoneApplicationPage.Resources>
