Windows Phone 8.1 app ProgressRing not showing - windows

Question

I am trying to show a progressring while storing data but I can not get it to show. My Xaml looks as follows:
<Page
x:Class="MyApp.MyPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:MyApp"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:Model="using:MyApp.Model"
mc:Ignorable="d"
Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<Page.BottomAppBar>
<CommandBar Height="58">
<AppBarButton Icon="Save" Label="" Click="AddAppBarButton_Click"/>
</CommandBar>
</Page.BottomAppBar>
<Grid x:Name="LayoutRoot">
<Grid.ChildrenTransitions>
<TransitionCollection>
<EntranceThemeTransition/>
</TransitionCollection>
</Grid.ChildrenTransitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<!-- Title Panel -->
<StackPanel Grid.Row="0" Margin="19,0,0,0">
<TextBlock Text="Name" Style="{ThemeResource BaseTextBlockStyle}" Margin="0,12,0,0"/>
<TextBox x:Name="nameTextBox" Margin="0,10,21.833,0" />
<TextBlock Text="Item" Style="{ThemeResource BaseTextBlockStyle}" Margin="0,12,-4.167,0"/>
<TextBox x:Name="itemTextBox" Margin="0,10,96.833,0" PlaceholderText="" Grid.ColumnSpan="2" />
<AppBarButton Grid.Column="1" HorizontalAlignment="Left" Icon="AddFriend" Label="" Margin="88.167,-2,0,0" VerticalAlignment="Top" Height="66" Click="ItemAppBarButton_Click"/>
<Grid Margin="0,0,-0.167,0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
</Grid>
<ListView x:Name="ItemListView" Height="379" Margin="0,10,21.833,0" IsItemClickEnabled="True" ItemClick="ItemListView_ItemClick">
<ListView.DataContext>
<Model:Person/>
</ListView.DataContext>
</ListView>
</StackPanel>
<ProgressRing Name="BusyProgressRing" HorizontalAlignment="Left" Margin="169,299,0,0" VerticalAlignment="Top"/>
</Grid>
</Page>
When I do:
BusyProgressRing.IsActive = true;
It does not show. Because at the end of my member function I do a BusyProgressRing.IsActive = false; and the rendering of the ring only occurs after my whole function is done.
Does anyone know how to solve this?

Answer 1

Yes, because ProgressRing does not appears in design time. It appears just in Runtime. You will see it when you deploy the application.
Additionally, ProgressRing always appears in the center of the screen. You don't have to write code for this.

Answer 2

Tested your code and the ProgressRing works. I did remove the margins and correct issue with row/column position of some UI element in your code and add
IsActive = "True"
to the ProgressRing. Your original code (with the margins) puts ProgressRing outside visible area when tested on my desktop.
