Preventing default mouse behavior in C# - wpf

Question

Is there an equivalent to Javascript's event.preventDefault() in C# (using wpf)?

I want to prevent the default behavior when left clicking anywhere in the screen.

private void Button_MouseDown(object sender, MouseButtonEventArgs e){
    // I want to use something like Javascript's e.preventDefault()
}

Answer 1

You might want to try e.Handled = true like so:

private void Button_MouseDown(object sender, MouseButtonEventArgs e){
    e.Handled = true;
}
