When a user is trying to login to my app, I am displaying a ContentDialog containing a few TextBlocks and a ProgressBar.
I choose ContentDialog because it is modal and blocks the user until the application collects required information and is ready to navigate to next page.
The following link shows the Content Dialog Class that is available for Windows Phone 8.1(Universal Apps).
The following code displays the code-behind that I have written to display the ContentDialog (I have temporarily put this in OnNavigatedTo for testing, will later move it to appropriate notification function)
//Progress Bar
ProgressBar bar = new ProgressBar();
bar.IsIndeterminate = true;
//Downloading Data text
TextBlock txt = new TextBlock();
txt.Text = "Downloading data...";
txt.FontSize = 17;
txt.Foreground = new SolidColorBrush(Colors.White);
txt.HorizontalAlignment = Windows.UI.Xaml.HorizontalAlignment.Center;
//This could take a few seconds
TextBlock txt2 = new TextBlock();
txt2.Text = "This could take a few seconds.";
txt2.FontSize = 17;
txt2.Foreground = new SolidColorBrush(Colors.White);
txt2.HorizontalAlignment = Windows.UI.Xaml.HorizontalAlignment.Center;
//Please do not close the application.
TextBlock txt3 = new TextBlock();
txt3.Text = "Please do not close the application.";
txt3.FontSize = 17;
txt3.Foreground = new SolidColorBrush(Colors.White);
txt3.HorizontalAlignment = Windows.UI.Xaml.HorizontalAlignment.Center;
StackPanel stk = new StackPanel();
stk.Children.Add(bar);
stk.Children.Add(txt);
stk.Children.Add(txt2);
stk.Children.Add(txt3);
ContentDialog dlg = new ContentDialog();
dlg.Content = stk;
SolidColorBrush color = new SolidColorBrush(Colors.Black);
color.Opacity = 0.7;
dlg.Background = color;
dlg.Margin = new Thickness(0, 250, 0, 0);
dlg.ShowAsync();
This is displayed as
Above you can see it is only covering part of the background
I want it to be displayed as
by making the full screen modal.
I have tried changing the height and other properties but was unable to get it to work.
I would be glad if someone can point me in the right direction.
