How to hide the Status bar in Windows Phone 8.1
(C#, XAML)?
In Windows Phone 8
it was done by setting shell:SystemTray.IsVisible="False"
at any page. But its not available in Windows Phone 8.1
With the release of Windows Phone 8.1 SDK comes a new StatusBar. The StatusBar replaces the SystemTray from Windows Phone Silverlight Apps. Unlike the SystemTray, the StausBar can only be accessed via code and some functionality has changed.
StatusBar statusBar = Windows.UI.ViewManagement.StatusBar.GetForCurrentView();
// Hide the status bar
await statusBar.HideAsync();
//Show the status bar
await statusBar.ShowAsync();
