Set static resource in code

Question

I have a few styles in my App.xaml file:

Answer 1

Why are you modifying the Style instead of setting the Background-Property of your targeted StackPanel directly? Since a 'Local value' has a higher precedence than 'Style setters' the value that you write into Background from code behind would be used

Means:

(1) Give a name to your stackpanel x:Name="spBla"

(2) Assign the Brush to the Background of spBla ( something like spBla.Background=Application.Current.Resources["styleRed"] as SolidColorBrush; )
