TcxCustomDataSource.IsRecordIdSupported Method

Indicates whether the record identifiers are supported.

Declaration

delphi
function IsRecordIdSupported: Boolean; virtual;

Returns

Type
Boolean

Remarks

Call this function to determine whether the record identifiers are supported by the current data source. These identifiers, unlike the record handles and indexes, are not changed when the number and order of records within the data set changes (see the TcxCustomDataSource class description for information on record indexes and record handles).

Call the GetRecordId method to obtain the record’s identifier via the record handle.
