This class provides additional information for the
ItemCommand event of the
Repeater control, which occurs when a button in an
item is clicked. This additional information consists of a
Item property, which represents the repeater item
where the button is located, and a CommandSource
property, which refers to the button in the item that fired this
event. Before using the CommandSource property,
you will have to cast it to the appropriate type.

It may seem that the Repeater.ItemCommand event
provides more than one way to determine its source. However, these
references are not equivalent. The sender
parameter indicates the Repeater instance where
the event took place, while the Item property
specifies the item in the Repeater and the
CommandSource property identifies the specific
button in the item.
