Disable Style in WPF XAML?

Is there anyway to turn off a style programatically?

As an example, I have a style that is linked to all textboxes

<Style TargetType="{x:Type TextBox}">

I would like to add some code to actually stop the style elements being used, so basically reverting back to the default control style.

I need a way to make a switch in my styles, so I can switch between Windows default style and my custom style through C# code.

Is there anyway to do this?

Thanks
