In c# you can do something like this:

Visibility lightThemeVisible = (Visibility)Resources["PhoneLightThemeVisibility"];
if (lightThemeVisible == System.Windows.Visibility.Visible)
{
// do code for light theme
}
else
{
// do code for dark theme
}

Hi Yogesh,

In Addition to João Cardoso.

You have to set few properties see below code snippet for the same.
XAML code

<TextBox GotFocus="textBox1_GotFocus" Background="YellowGreen" BorderBrush="Red" BorderThickness="1" Foreground="Black" Height="72" HorizontalAlignment="Left" Margin="94,414,0,0" Name="textBox1" Text="" VerticalAlignment="Top" Width="281" />

C# Code

private void textBox1_GotFocus(object sender, RoutedEventArgs e)
        {
            Visibility lightThemeVisible = (Visibility)Resources["PhoneLightThemeVisibility"];
            if (lightThemeVisible == System.Windows.Visibility.Visible)
            {
                // do code for light theme
                textBox1.Background = new SolidColorBrush(Colors.Red);
            }
            else
            {
                // do code for dark theme
                textBox1.Background = new SolidColorBrush(Colors.Green);
            }
        }

However you can also have a look this article for handling Theme in WP7 TextBox Light theme problems - the solution

Hope it helps.

Maybe it is possible to use converter to do that. I never try but you can check
