The DeleteCommand event is raised when the Delete button for an item in the DataList control is clicked.
The EditCommand event is raised when the Edit button for an item in the DataList control is clicked.
The ItemCommand event is raised when any button for an item in the DataList control is clicked. This allows you to programmatically test for when a specific command button is clicked and take appropriate action. This event is commonly used to handle custom command buttons for the DataList control.
