If you want to change background on user click, in the click event handler use 

            Button button1 = sender as Button;
            button1.Backgorund = new SolidColorBrush(Colors.Red);

to change the background color.

Else bind the background property for each button and change its value on iteration of the items in the listbox.

Without seeing how you've tried to access this is in code it's impossible to say why what you're doing isn't working.

However it'll be much easier if you use databinding to set the color of the templateitem
