Obtaining data from any UI element it is bound to
When a user who is working with your application performs a certain action, it's often essential to know on what object this action will be executed. For example, if a user clicks on a Delete button on an item, it's essential that you know which item is clicked so that you can write the correct code to delete that item. Also, when a user wants to edit an item in a list, it's necessary that you—the programmer—know which item in the list the user wants to edit.
