C# Change A Button's Background Color

Question

How can the background color of a button once another button is pressed?

What I have at the moment is:

ButtonToday.Background = Color.Red;
         


        

Answer 1

// WPF

// Defined Color
button1.Background = Brushes.Green;

// Color from RGB
button2.Background = new SolidColorBrush(Color.FromArgb(255, 0, 255, 0));
