• XAML行列定義

  <Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}">        <Grid.RowDefinitions>            <RowDefinition></RowDefinition>            <RowDefinition Height="Auto"></RowDefinition>            <RowDefinition Height="Auto"></RowDefinition>        </Grid.RowDefinitions>       <Grid.ColumnDefinitions>                <ColumnDefinition></ColumnDefinition>                <ColumnDefinition></ColumnDefinition></Grid.ColumnDefinitions> </Grid>

• 儲存配置資料

  //恢複資料protected override void OnNavigatedTo(NavigationEventArgs e){ApplicationDataContainer container = ApplicationData.Current.LocalSettings;if (container.Values.ContainsKey("ListBoxIndex")){MyListBox.SelectedIndex = (int)ApplicationData.Current.LocalSettings.Values["ListBoxIndex"];}}//儲存資料private void MyListBox_SelectionChanged(object sender, SelectionChangedEventArgs e){ListBox list = sender as ListBox;if (list != null){if (list.SelectedIndex > -1){ApplicationDataContainer myContainer = ApplicationData.Current.LocalSettings;myContainer.Values["ListBoxIndex"] = list.SelectedIndex;}} }

• MessageDialog

  private /*async*/ void TextBlock_Tapped(object sender, TappedRoutedEventArgs e)        {            MessageDialog msg = new MessageDialog("測試成功.");            msg.Commands.Add(new UICommand("Yes"));            msg.Commands.Add(new UICommand("No"));            msg.Commands.Add(new UICommand("林武"));            /*IUICommand result =await*/ msg.ShowAsync();        }

  去掉其中的注釋後，需要等待對話方塊顯示後，函數才會執行完，使用的是非同步機制同步化的方法。此外，MessageBox最多隻支援3個按鈕。非必要時不建議使用該方法顯示訊息。
