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.

Available Edit Repository Item Types

Every repository item type (a TcxEditRepositoryItem class descendant) defines the corresponding in-place editor type and stores its settings accessible through the Properties property. The following table lists all available edit repository items and corresponding in-place editor classes:

Repository Item Type	In-Place Editor	Description
TcxEditRepositoryBarCodeItem	TdxBarCode	A barcode control without user input functionality.
TcxEditRepositoryBlobItem	TcxBlobEdit	A Binary Large Object (BLOB) editor.

TcxEditRepositoryCalcItem	TcxCalcEdit	A single-line editor with a drop-down calculator window.
TcxEditRepositoryCheckBoxItem	TcxCheckBox	A check box editor with support for three states.
TcxEditRepositoryCheckComboBox	TcxCheckComboBox	A combo box editor that can display items with check boxes.

Warning Do not use repository items to share settings between multiple lookup editors because these settings include data binding options. A repository item shared between multiple lookup editors binds them to the same dataset. This scenario may lead to data update and synchronization issues that are difficult to detect and identify.
TcxEditRepositoryExtLookupComboBoxItem	TcxExtLookupComboBox	A lookup editor that displays a Data Grid View in a drop-down window. Warning Do not use repository items to share settings between multiple lookup editors because these settings include data binding options. A repository item shared between multiple lookup editors binds them to the same dataset. This scenario may lead to data update and synchronization issues that are difficult to detect and identify.
TcxEditRepositoryFontNameComboBox	TcxFontNameComboBox	A combo box that allows users to switch between font typefaces.
TcxEditRepositoryFormattedLabel	TdxFormattedLabel	A formatted label editor without user input functionality.

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;
