| Object Model > True DataControl Objects and Collections > RangeCondition Object, RangeConditions Collection |
Each Field object representing a True DataControl field has a RangeConditions collection, which can contain zero or more RangeCondition objects. Use the RangeConditions property to access the RangeConditions collection for a Field object. The RangeConditions collection is unavailable in True DataControl Lite.
A RangeCondition object represents a condition that restricts the set of records fetched to the True DataControl recordset by specifying that the field must be equal to (or satisfy other comparison with) the result of an expression.
Range conditions are better optimized for performance than filters. Using range conditions is the preferred way to implement master-detail relationships between True DataControl controls.
