TcxCustomEdit.RepositoryItem Property

Specifies an edit repository item that stores editor settings.

Declaration

property RepositoryItem: TcxEditRepositoryItem read; write;

Property Value

Type	Description
TcxEditRepositoryItem	An edit repository item component.

Remarks

An edit repository item (a TcxEditRepositoryItem class descendant) is a non-visual component designed to define and store editor settings. Repository items are useful when you need to share the same settings between multiple editors of the same type. To accomplish this goal, you can assign the same repository item to RepositoryItem properties of all target editors.

Code Example: Shared Barcode Editor Settings

The following code example creates a barcode repository item, selects QR Code as the barcode type, customizes its settings, and assigns the created repository item to two existing standalone unbound barcode editors:

Delphi

uses cxEdit, cxEditRepositoryItems;
// ...
var
  ABarCodeRepositoryItem: TcxEditRepositoryBarCodeItem;
  ARepositoryItem: TcxEditRepositoryItem;
  AQRCodeSymbology: TdxBarCodeQRCodeSymbology;
begin
  ARepositoryItem := cxEditRepository1.CreateItem(TcxEditRepositoryBarCodeItem);
  ABarCodeRepositoryItem := TcxEditRepositoryBarCodeItem(ARepositoryItem);
  ABarCodeRepositoryItem.Properties.BarCodeSymbologyClass := TdxBarCodeQRCodeSymbology;
  AQRCodeSymbology := TdxBarCodeQRCodeSymbology(ABarCodeRepositoryItem.Properties.Symbology);
  AQRCodeSymbology.ErrorCorrectionLevel := eclH; // Increases encoded information redundancy
  AQRCodeSymbology.CompactionMode := qrmAlphaNumeric; // Changes the information encoding mode
  // Assigns the created repository item to two existing unbound barcode editors
  dxBarCode1.RepositoryItem := ABarCodeRepositoryItem;
  dxBarCode2.RepositoryItem := ABarCodeRepositoryItem;
end;

C++

#include "cxEdit.hpp"
#include "cxEditRepositoryItems.hpp"
// ...
  TcxEditRepositoryBarCodeItem *ABarCodeRepositoryItem;
  TcxEditRepositoryItem *ARepositoryItem;
  TdxBarCodeQRCodeSymbology *AQRCodeSymbology;
  // ...
  ARepositoryItem = cxEditRepository1->CreateItem(__classid(TcxEditRepositoryBarCodeItem));
  ABarCodeRepositoryItem = dynamic_cast<TcxEditRepositoryBarCodeItem*>(ARepositoryItem);
  ABarCodeRepositoryItem->Properties->BarCodeSymbologyClass = __classid(TdxBarCodeQRCodeSymbology);
  AQRCodeSymbology = dynamic_cast<TdxBarCodeQRCodeSymbology*>(ABarCodeRepositoryItem.Properties.Symbology);
  AQRCodeSymbology->ErrorCorrectionLevel = eclH;  // Increases encoded information redundancy
  AQRCodeSymbology->CompactionMode = qrmAlphaNumeric; // Changes the information encoding mode
  // Assigns the created repository item to two existing unbound barcode editors
  dxBarCode1->RepositoryItem = ABarCodeRepositoryItem;
  dxBarCode2->RepositoryItem = ABarCodeRepositoryItem;
