WPF How to know the current button pressed among multiple buttons

Question

I am having multiple buttons with contents 1, 2, 3, 4, 5... like this. All buttons are using same function on Click event.

Answer 1

I tend to deal with this problem by attaching an object to the button's tooltip property. You can then get it back like this:

void EditMe(object sender, RoutedEventArgs e)
{
    Button x = sender as Button;

    if (x != null)
    {
        int id = (x.ToolTip as TT).Id;
    }
}

The TT object in this example looks like:

        public class TT
        {
            public int Id { get; set; }
            public string Text { get; set; }
            public override string ToString()
            {
                return Text;
            }
        }

Which displays the tooltip text on the UI and makes the Id accessible in the click handler.
