TcxCustomInplaceEditContainer.RepositoryItem Property

Specifies an edit repository item for the data item.

Declaration

property RepositoryItem: TcxEditRepositoryItem read; write;

Property Value

Type	Description
TcxEditRepositoryItem	An edit repository item component.

Remarks

A data item in a container control can use any editor shipped with the ExpressEditors Library as an in-place editor for cell edit operations. An in-place editor instance exists (and, therefore, has its own WinAPI handle) only when a data item cell is being edited. Otherwise, the data item displays a static editor image for resource usage optimization.

To assign an in-place editor to the data item, you can create and configure an edit repository item component, and then assign it to the RepositoryItem property.

Tip

Edit repository items are useful when you need to share in-place editor settings between multiple data items in a container control or change active editor settings in OnGetEditProperties and OnGetEditingProperties event handlers.

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.
TcxEditRepositoryCheckGroupItem	TcxCheckGroup	An editor designed to display a set of check boxes.
TcxEditRepositoryColorComboBox	TcxColorComboBox	A color combo box editor.
TcxEditRepositoryColorEdit	TdxColorEdit	An editor designed to select a color in a color gallery embedded into 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.
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.

Note

The RepositoryItem property has priority over Properties, PropertiesClass, and PropertiesClassName properties. These properties have no effect when the RepositoryItem property is specified.

Code Example: Shared In-Place Editor Settings

The following code example creates two unbound tree list columns and uses a date editor repository item to assign an in-place date editor to them:

Delphi

uses cxCalendar, cxEditRepositoryItems;
// ...
var
  AColumn1, AColumn2: TcxTreeListColumn;
  ARepositoryItem: TcxEditRepositoryDateItem;
begin
  AColumn1 := cxTreeList1.CreateColumn; // Creates a new unbound column
  AColumn2 := cxTreeList2.CreateColumn; // Creates another unbound column
  // Creates a repository item that defines a date editor and stores its settings
  ARepositoryItem := cxEditRepository1.CreateItem(TcxEditRepositoryDateItem) as TcxEditRepositoryDateItem;
  ARepositoryItem.Properties.ShowToday := False; // Hides the "Today" link
  ARepositoryItem.Properties.DateButtons := [btnClear, btnToday]; // Adds the "Today" button
  AColumn1.RepositoryItem := ARepositoryItem;
  AColumn2.RepositoryItem := ARepositoryItem;
end;

C++

#include "cxCalendar.hpp"
#include "cxEditRepositoryItems.hpp"
// ...
  TcxTreeListColumn *AColumn1, *AColumn2;
  TcxEditRepositoryDateItem *ARepositoryItem;
  // ...
  AColumn1 = cxTreeList1->CreateColumn(); // Creates a new unbound column
  AColumn2 = cxTreeList1->CreateColumn(); // Creates another unbound column
  // Creates a repository item that defines a date editor and stores its settings
  ARepositoryItem = dynamic_cast<TcxEditRepositoryDateItem*>(cxEditRepository1->CreateItem(__classid(TcxEditRepositoryDateItem)));
  ARepositoryItem->Properties->ShowToday = false; // Hides the "Today" link
  ARepositoryItem->Properties->DateButtons = TDateButtons() << btnClear << btnToday; // Adds the "Today" button
  AColumn1->RepositoryItem = ARepositoryItem;
  AColumn2->RepositoryItem = ARepositoryItem;

Default In-Place Editors

A data item in a container control uses the default in-place editor if Properties, PropertiesClass, PropertiesClassName, and RepositoryItem properties are unspecified. The container control item uses one of the following in-place editors as default depending on DataBinding.ValueType and DataBinding.ValueTypeClass property values:

ValueType[1] Value	ValueTypeClass[1] Value	Default Editor
Boolean	TcxBooleanValueType	TcxCheckBox
Currency	TcxCurrencyValueType	TcxCurrencyEdit
DateTime	TcxDateTimeValueType	TcxDateEdit
FMTBcd	TcxFMTBcdValueType	TcxCurrencyEdit
SQLTimeStamp	TcxSQLTimeStampValueType	TcxDateEdit
Any other value	Any other value	TcxTextEdit

Footnotes

1. DataBinding.ValueType and DataBinding.ValueTypeClass property values define the default in-place editor for the container control item regardless of the active data access mode.
