There might be a case where you need to set the background color of a button in code rather than in XAML. Or you might define a style in XAML with a particular button background color, but would like to change the background color in an event handler. For example, let’s say you created the following button in XAML:
<Button Content=”My Button”
Now let’s say that when the user clicks the button you want to change the button’s background color to give another way of indicating the button has been selected. You can do the following in C#:
private void RegisterSelection_Click(object sender, RoutedEventArgs e)
Button btn = (Button)sender;
btn.Background = App.Current.Resources[“PhoneChromeBrush”] as SolidColorBrush;
I am using this in an app I am currently working on and it works well. Give it a try.
