Occurs each time a different record in the dataset becomes the active record and filtering is enabled.
property OnFilterRecord: TFilterRecordEvent;
__property TFilterRecordEvent OnFilterRecord;
Write an OnFilterRecord event handler to specify for each record in a dataset whether it should be visible to the application. To indicate that a record passes the filter condition, the OnFilterRecord event handler must set the Accept parameter to true. To exclude a record, set the Accept parameter to false. Most TDataSet descendants (such as ADO datasets or BDE-based datasets) initialize Accept to true before calling the OnFilterRecord event handler.
Use an OnFilterRecord event handler to filter records using a criterion that can't be implemented using the Filter property. For example, using the Filter property, field comparisons are not supported against local tables (Paradox, dBASE, Access, FoxPro), but an OnFilterRecord event handler can implement any criterion at all.
