Remove / hide the Bing map offline message when offline

Question

I'm developing a Windows Phone app that uses the older WP7 Microsoft.Phone.Controls.Maps.Map / Bing Map control.

The map tiles are being served up from a local source so the app doesn't not need a network connection to work. Unfortunately the map control insists on showing an "Unable to contact Server. Please try again later." message over the map when offline.

Does anyone know of a method to remove / hide this message?

Just in case you're curious - I'm developing a WP8 app but using the depreciated WP7 Bing map control as the new WP8 map control provides no method for replacing the Bing base map.

i think this may suits you better:

void YourPage_Loaded(object sender, RoutedEventArgs e)
        {         
            m_Map.ZoomLevel = 11;          
            m_Map.LayoutUpdated += m_Map_LayoutUpdated; 
        }

        void m_Map_LayoutUpdated(object sender, EventArgs e)
        {
            if (!isRemoved) 
            {
                RemoveOverlayTextBlock();
            }
        }

        void  RemoveOverlayTextBlock()
        {             
            var textBlock = m_Map.DescendantsAndSelf.OfType<TextBlock>()
                           .SingleOrDefault(d => d.Text.Contains("Invalid Credentials") ||
                                                 d.Text.Contains("Unable to contact Server"));
            if (textBlock != null)
            {
                var parentBorder = textBlock.Parent as Border;
                if (parentBorder != null)
                {
                    parentBorder.Visibility = Visibility.Collapsed;
                }
                isRemoved = true;   
            }
       }

You have to include a class LinqToVisualTree witch can be downloaded from here. And here is the original post
