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

In WPF, the background is not a Color, it is a Brush. So, try this for starters:

using System.Windows.Media;

// ....

ButtonToday.Background = new SolidColorBrush(Colors.Red);

More sensibly, though, you should probably look at doing this in your Xaml instead of in code.
