The list based controls in Flex has the built in support for the drag and drop.So to support the drag and drop operations for the non-list based components(here TextInput) we must handle the drag and drop events.
Go through the classes involded in the drag and drop operations,drag and drop events for a drag initiator,drag and drop events for a drop target to explicitly handle the drag and drop and to fully understand the drag and drop operations functionality.
For now enjoy the below demo and code.
