Defines the text displayed when the control has null value assigned.

Remarks

Property specifies the string displayed when control has null value. Control has null value when no value is attached to the control or when null value is entered by the user. User can enter null value by clicking NullButton,

It is logical to change the string, representing null values, according to the meaning of entered or displayed null values. If null value retrieves no records from the data source, than the value of the property should be something like (None). If null value retrieves all records from the data source, than the value of the property should be something like (All).
