Can not see text in TextBox when it is disabled

build a metro application (Windows 8 Release Preview) using Visual studio 2012 the application has only a text box and a button click on the button only Enable/Disable the text box when I disable it the text in it is not visible and when I enable it it is grayed out until it get a focus.

Code:

[/B]namespace App2
{
/// <summary>
/// An empty page that can be used on its own or navigated to within a Frame.
/// </summary>
   public sealed partial class MainPage : Page
   {
     public MainPage()
     {
       this.InitializeComponent();
     }
/// <summary>
/// Invoked when this page is about to be displayed in a Frame.
/// </summary>
/// <param name="e">Event data that describes how this page was reached. The Parameter
/// property is typically used to configure the page.</param>
   protected override void OnNavigatedTo(NavigationEventArgs e)
  {
  } 
  private void Button_Click_1(object sender, RoutedEventArgs e)
  {
    TextBox1.IsEnabled = !TextBox1.IsEnabled;
  }
 }
}

[XAML]
<Page
x:Class="App2.MainPage"
IsTabStop="false"

<Button Content="Button" HorizontalAlignment="Left" Margin="409,181,0,0" VerticalAlignment="Top" Click="Button_Click_1"/>

[/XAML]

Are you sure this is not correct behavior? Or are you asking if it is?

This and a million other things may in fact be simply the way the Metro UI works. It is /completely/ different from the standard windows UI elements and behaviour we've gotten used to in the last 15 years.

Is the documentation provided with the dev tool complete enough to explain the expected behavior for a text box?

I got an answer from Microsoft that this is the default behavior of a text box that the background and the text color is the same for a disabled TextBox very odd that a default behaviorof a control is buggy (Text can no be seen when it is disabled) I do not think any one needs this behavior.

Heh, that statement could be used in about 50 places when referring to something in the metro UI

It's a completely new beast... need to figure out how best to use the new and and the odd. I agree though "Disabled" != "Hidden". That was (and should be) a separate state :/

Now you may have to change the text color yourself and ignore input on it or something :/
