virtual event DataEventHandler^ DataEvent {
    void add (DataEventHandler^ value) abstract;

Remarks

The DataEventArgs.Status property is divided into four bytes. Status is divided as follows: The high word high byte is the row, the high word low byte is the column. The low word is the event type (for example, TouchUp, TouchDown, TouchMove).

The high word contains additional data depending on the event type. When the event type is TouchUp, TouchDown, or TouchMove, the high word indicates where the touch occurred. The low byte contains the column position and the high byte contains the row position, with valid values ranging from 0-255.

Data events can be filtered at the remote order display device by setting the EventType property. The EventUnitID property is updated before the event is delivered.
