An object is associated with one or more controls in a software application. An object associated with a control determines the operation of the data entry user interface when the data entry user interface is being employed to enter data into that control. More particularly, the object may communicate interface characteristics to a component that is responsible for providing the user interface to the user. Such a component may be, for example, a shared software module that renders the user interface on a display, receives input data from the user through the user interface, and routes the entered data to a designated destination. Alternately, the object itself may create a user interface having the specified characteristics.
