Property Value

Type	Description
Boolean	true, if the detail initially has no data; otherwise, false.

Remarks

Initially, the IsEmpty property value indicates that data is actually present within the detail. If the detail contains data, the IsEmpty property’s initial value is false. Otherwise, the property initially returns true.

Set the IsEmpty property to true to indicate that the processed detail has no data.
