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

Solution

  • 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);
    }
