TcxEditRepositoryDateItem Class

A repository item that stores date editor settings.

Declaration

TcxEditRepositoryDateItem = class(
    TcxEditRepositoryItem
)

Remarks

A date editor displays a date and allows users to select a date in a drop-down calendar. In addition, date editors have time selection functionality.

The TcxEditRepositoryDateItem class overrides the Properties property that allows you to access and customize date editor settings.

Edit Repository Items and Standalone Editors

Edit 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 edit repository item to RepositoryItem properties of all target editors.

Edit Repository Items and Container Controls

A container control item (such as a toolbar edit item or a column (or any other data item) in a Data Grid, Vertical Grid, or Tree List control) can embed an in-place editor shipped with the ExpressEditors Library. An in-place editor exists (and, therefore, has its own WinAPI handle) only when the target container control item is being edited. Otherwise, the container control item displays a static editor image for resource usage optimization.

Create a Date Editor Repository Item at Design Time

To create a date editor repository item at design time, double-click a TcxEditRepository component to invoke its collection editor.

The collection editor dialog allows you to manage repository items. Click the Add… button to invoke a repository item creation dialog.

Select the DateEdit item and click the Ok button to create a date editor repository item.

Create a Date Editor Repository Item in Code

The following code example creates a date editor repository item, customizes editor settings, and assigns the created repository item to two existing unbound date editors:

Delphi

uses cxEdit, cxEditRepositoryItems;
// ...
var
  ADateRepositoryItem: TcxEditRepositoryDateItem;
  ARepositoryItem: TcxEditRepositoryItem;
begin
  ARepositoryItem := cxEditRepository1.CreateItem(TcxEditRepositoryDateItem);
  ADateRepositoryItem := ARepositoryItem as TcxEditRepositoryDateItem;
  ADateRepositoryItem.Properties.Kind := ckDateTime; // Allows users to specify both date and time
  // Switches the editor to a touch-friendly UI version in a drop-down window
  ADateRepositoryItem.Properties.View := cavTouchUI;
  // Assigns the created repository item to two existing unbound date editors
  cxDateEdit1.RepositoryItem := ADateRepositoryItem;
  cxDateEdit2.RepositoryItem := ADateRepositoryItem;
end;

C++

#include "cxEdit.hpp"
#include "cxEditRepositoryItems.hpp"
// ...
  TcxEditRepositoryDateItem *ADateRepositoryItem;
  TcxEditRepositoryItem *ARepositoryItem;
  // ...
  ARepositoryItem = cxEditRepository1->CreateItem(__classid(TcxEditRepositoryDateItem));
  ADateRepositoryItem = dynamic_cast<TcxEditRepositoryDateItem*>(ARepositoryItem);
  ADateRepositoryItem->Properties->Kind = cxDateTime; // Allows users to specify both date and time
  // Switches the editor to a touch-friendly UI version in a drop-down window
  ADateRepositoryItem->Properties->View = cavTouchUI;
  // Assigns the created repository item to two existing unbound date editors
  cxDateEdit1->RepositoryItem = ADateRepositoryItem;
  cxDateEdit2->RepositoryItem = ADateRepositoryItem;

Date Editor Repository Item Deletion

To delete all date editor repository items in an edit repository component, call its RemoveItems procedure and pass a reference to the TcxEditRepositoryDateItem class as a parameter.

If you need to delete an individual date editor repository item, release it directly in code (call the Free procedure in Delphi or use the delete keyword in C++Builder).
