Pass DataContext to Silverlight IValueConverter

When passing DataContext to a Silverlight IValueConverter the following method is not supported:

<TextBox Text="{Binding Detail,
Mode=TwoWay, NotifyOnValidationError=True,  ValidatesOnExceptions=True}" 
IsEnabled={Binding ,Converter="{StaticResource contactDetailsColorConverter}} >

</TextBox>

Instead you need to translate the the above out to its expanded tag version

<TextBox Text="{Binding Detail, Mode=TwoWay, NotifyOnValidationError=True, ValidatesOnExceptions=True}"  >

<TextBox.IsEnabled>

<Binding Converter="{StaticResource contactDetailsColorConverter}"/>

</TextBox.IsEnabled>

</TextBox>
