What you need to do is bind the background property to the actual property that contains the Locked/Editable value, and then use a value converter to change the colour as appropriate. Here's a sample of the converter:
C#
namespace MySample.Converters
{
  using System;
  using System.Globalization;
  using System.Windows.Data;
  using System.Windows.Media;

  /// <summary>
  /// Converter to determine whether or not a number is negative, and apply 
  /// conditional formatting if it is.
  /// </summary>
  public class StatusTextColorConverter : IValueConverter
  {
    #region IValueConverter Members
    /// <summary>
    /// Convert from the value to the colour brush.
    /// </summary>
    /// <param name="value">The value to convert.</param>
    /// <param name="targetType">The parameter is not used.</param>
    /// <param name="parameter">The parameter is not used.</param>
    /// <param name="culture">The parameter is not used.</param>
    /// <returns>The populated colour brush.</returns>
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
      var brush = new SolidColorBrush(Colors.White);

      if (value != null && value == "Locked")
      {
        brush = Colors.Yellow;
      }

      return brush;
    }

    /// <summary>
    /// Unused in this implementation.
    /// </summary>
    /// <param name="value">The parameter is not used.</param>
    /// <param name="targetType">The parameter is not used.</param>
    /// <param name="parameter">The parameter is not used.</param>
    /// <param name="culture">The parameter is not used.</param>
    /// <returns>The parameter is not used.</returns>
    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
      throw new NotImplementedException();
    }

    #endregion
  }
}
Then you declare your converter as a reference in your XAML resources:
XML
<conv:StatusTextColorConverter x:Key="statusTextColorConverter"/>
(Here conv is a link to the converter namespace). Finally, you add it to your cell grid style:
XML
<Setter Property="Background" Value="{Binding Path=PropertyContainingEditableText, Converter={StaticResource statusTextColorConverter}}}"/>
By doing this, you remove the need to implement a UI based logic item in your ViewModel.

Forgive your enemies - it messes with their heads
