TcxCustomDataController.ItemExpressions Property

Specifies calculated field expressions for data items by their indexes.

Declaration

property ItemExpressions[AItemIndex: Integer]: string read; write;

Property Value

Type
string

Remarks

Pass an index of the required data item as the AItemIndex parameter to assign/read a calculated field expression to/from the data item. Call the IsItemExpression function for the same index to identify if an assigned expression is active (that is, if the data item corresponds to a calculated column or row in a container control).

Note

The data controller (a TcxCustomDataController class descendant) must support calculated fields.
