Evidently, you are not supposed to change the RootVisual in a Win Phone 7 application. There was a forum post posed by Matt Hidinger and answered by Peter Torr about Changing the RootVisual that indicates this might cause problems during the approval process.
As a result, I've updated my sample to not require wrapping the root level PhoneApplicationFrame with a Grid. It turns out, most pages already have a Grid as their LayoutRoot element and you can just pass this in to a new RootPaneBusyService and use it in the same manner. So instead of passing the App.Current.RootVisual as Grid, we pass the LayoutRoot.
protected override void OnNavigatedTo( System.Windows.Navigation.NavigationEventArgs e) { base.OnNavigatedTo(e); var busyServ = new RootPanelBusyService(this.LayoutRoot); this.DataContext = new MainPageVM(busyServ); }I've also updated the CreateBusyElement method to detect how many rows and columns are in the passed in root visual and set the ColumnSpan and RowSpan accordingly.
// Set the row and column span's if the root is a grid. if (rootVisual is Grid) { var gridRoot = rootVisual as Grid; int rowSpan = 1; if (gridRoot.RowDefinitions != null) rowSpan = gridRoot.RowDefinitions.Count + 1; int columnSpan = 1; if (gridRoot.ColumnDefinitions != null) columnSpan = gridRoot.ColumnDefinitions.Count + 1; Grid.SetRowSpan(root, rowSpan); Grid.SetColumnSpan(root, columnSpan); }Download the updated sample
