InputDialog вопрос позиционирования

Question

В окна Маркете, я имею следующую страницу

<common:LayoutAwarePage 
x:Class="Gapp_metro.Pages.DocumentsPage"

    <Grid.RowDefinitions> 
     <RowDefinition Height="Auto" /> 
     <RowDefinition /> 
     <RowDefinition Height="50" /> 
    </Grid.RowDefinitions> 

    <Grid Style="{StaticResource HeaderGridStyle}" > 
     <Grid.ColumnDefinitions> 
      <ColumnDefinition Width="Auto"/> 
      <ColumnDefinition Width="*"/> 
     </Grid.ColumnDefinitions> 

     <Button Click="GoBack" IsEnabled="{Binding Frame.CanGoBack}" Style="{StaticResource BackButtonStyle}" /> 
     <TextBlock x:Name="pageTitle" Grid.Column="1" Text="{Binding Title}" Style="{StaticResource PageHeaderTextStyle}" />

    <Grid Grid.Row="1" Style="{StaticResource ContentGridStyle}" VerticalAlignment="Center">

<Page.BottomAppBar> 
    <AppBar x:Name="appBar" Style="{StaticResource AppBarStyle}"> 
     <StackPanel HorizontalAlignment="Right" Orientation="Horizontal"> 
      <Button Click="OnAddButtonClick" Style="{StaticResource AddAppBarButtonStyle}" /> 
      <Button Click="OnUploadButtonClick" Style="{StaticResource UploadAppBarButtonStyle}" /> 
      <Button Click="OnPhotoButtonClick" Style="{StaticResource PhotoAppBarButtonStyle}" /> 
     </StackPanel> 
    </AppBar> 
</Page.BottomAppBar> 

и в моем коде позади меня есть эта функция для «Click =» OnAddButtonClick «»

private async void OnAddButtonClick(object sender, RoutedEventArgs e) 
    { 
     var dialog = new InputDialog(); 
     dialog.BackgroundStripeBrush = new SolidColorBrush(Color.FromArgb(255, 149, 191, 0)); 
     dialog.Background = new SolidColorBrush(Color.FromArgb(255, 149, 191, 0)); 
     dialog.BorderBrush = new SolidColorBrush(Color.FromArgb(255, 149, 191, 0)); 
     Style buttonStyle = new Style() { TargetType = typeof(Button) }; 
     buttonStyle.Setters.Add(new Setter(BackgroundProperty, new SolidColorBrush(Colors.Transparent))); 
     dialog.ButtonStyle = buttonStyle; 
     var result = await dialog.ShowAsync(App.Current.Resources["createFolder"] as String, App.Current.Resources["newFolderName"] as String, App.Current.Resources["create"] as String, App.Current.Resources["close"] as String); 

     dialog.VerticalAlignment = VerticalAlignment.Top; 
     dialog.Margin = new Thickness(0, 0, 0, 0); 
.... 

, но когда я нажимаю кнопку добавления, диалог ввода всегда появляется в центре экрана, даже если я попытался добавить вертикальное выравнивание и поля. довольно уверен, что я пропустил что-то глупое

как я могу показать его сверху?

Answer 1

Перед тем, как позвонить ShowAsync, необходимо установить VerticalAlignment и Margin.
