Initiate
<         


        

Answer 1

Well there are two ways of doing this:

Cast the DataContext

 void button1_Click(object sender, RoutedEventArgs e)
 {
    var button = sender as Button;
    var code = ((Coupon)button.DataContext).Code;
 }

Or use the Tag property which is a generic state property

then

void button1_Click(object sender, RoutedEventArgs e)
{
    var button = sender as Button;
    var code = button.Tag;
}
