Description

Functions and Procedures

function FindRec(const DBGrid: TDBGrid; SortList: boolean = false): boolean; overload;

show DBFind dialog for DBGrid (Columns collection is used)

function FindRec(const DataSet: TDataSet; SortList: boolean = false): boolean; overload;

show DBFind dialog for Dataset (Fields collection is used)

function FindRecMD(const DBGrid: TDBGrid; MasterSource: TDataSource; const MasterField, DetailField: string; ChangeMasterDetailProc: TChangeMasterDetailProc; SortList: boolean = false): boolean; overload;

show DBFind dialog for detail DBGrid which use master-detail relationship

function FindRecMD(const DataSet: TDataSet; MasterSource: TDataSource; const MasterField, DetailField: string; ChangeMasterDetailProc: TChangeMasterDetailProc; SortList: boolean = false): boolean; overload;

show DBFind dialog for detail Dataset which use master-detail relationship

function FindRecDetails(const DBGrid: TDBGrid; const FindDefDetailArr: TFindDefDetailArr; SortList: boolean = false): boolean; overload;

show DBFind dialog for DBGrid and list of details datasets

function FindRecDetails(const DataSet: TDataSet; const FindDefDetailArr: TFindDefDetailArr; SortList: boolean = false): boolean; overload;

show DBFind dialog for Dataset and list of details datasets

function FindRecSorted(const GridOrDataSet: TObject): boolean;

only for backward compability

function FindRecMDSorted(const GridOrDataSet: TObject; MasterSource: TDataSource; const MasterField, DetailField: string; ChangeMasterDetailProc: TChangeMasterDetailProc): boolean;

only for backward compability

Types

TChangeMasterDetailProc = procedure(DataSet: TDataSet; MasterSource: TDataSource; ShowAll: boolean) of object;

Callback procedure for changing of master-detail relationship during searching

TFindDefDetailArr = array of TFindDefDetailRec;

define array for master-detail searching

Variables

rDBFindForm: TrDBFindForm;
