Question

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

For setting the style to default,

In XAML use,

<TextBox Style="{x:Null}" />

In C# use,

myTextBox.Style = null;

If style needs to be set as null for multiple resources, see CodeNaked’s response.

In code Behind I think this is what you are trying to achieve:

Style myStyle = (Style)Application.Current.Resources["myStyleName"];
    
public void SetDefaultStyle()
{
    if(Application.Current.Resources.Contains(typeof(TextBox)))
        Application.Current.Resources.Remove(typeof(TextBox));
    
    Application.Current.Resources.Add(typeof(TextBox),      
                                      new Style() { TargetType = typeof(TextBox) });
}
    
public void SetCustomStyle()
{
    if (Application.Current.Resources.Contains(typeof(TextBox)))
        Application.Current.Resources.Remove(typeof(TextBox));
    
    Application.Current.Resources.Add(typeof(TextBox), 
                                      myStyle);
}
