Code Example: Shared In-Place Editor Settings

The following code example creates two unbound Table View columns in a Data Grid control and uses a memo repository item to assign an in-place memo editor to them:

Delphi

uses cxEdit, cxEditRepositoryItems;
// ...
var
  AColumn1, AColumn2: TcxGridColumn;
  ARepositoryItem: TcxEditRepositoryMemoItem;
begin
  AColumn1 := cxGrid1TableView1.CreateColumn; // Creates a new unbound column
  AColumn2 := cxGrid1TableView1.CreateColumn; // Creates another unbound column
  // Creates a repository item that defines a memo editor and stores its settings
  ARepositoryItem := cxEditRepository1.CreateItem(TcxEditRepositoryMemoItem) as TcxEditRepositoryMemoItem;
  ARepositoryItem.Properties.ScrollBars := ssVertical; // Enables a vertical scroll bar
  ARepositoryItem.Properties.VisibleLineCount := 8; // Limits the number of simultaneously visible lines
  // Assigns the created repository item to both new columns
  AColumn1.RepositoryItem := ARepositoryItem;
  AColumn2.RepositoryItem := ARepositoryItem;
end;

C++

#include "cxEdit.hpp"
#include "cxEditRepositoryItems.hpp"
// ...
  TcxGridColumn *AColumn1, *AColumn2;
  TcxEditRepositoryMemoItem *ARepositoryItem;
  // ...
  AColumn1 = cxGrid1TableView1->CreateColumn(); // Creates a new unbound column
  AColumn2 = cxGrid1TableView1->CreateColumn(); // Creates another unbound column
  // Creates a repository item that defines a memo editor and stores its settings
  ARepositoryItem = dynamic_cast<TcxEditRepositoryMemoItem*>(cxEditRepository->CreateItem(__classid(TcxEditRepositoryMemoItem)));
  ARepositoryItem->Properties->ScrollBars = ssVertical; // Enables a vertical scroll bar
  ARepositoryItem->Properties->VisibleLineCount = 8; // Limits the number of simultaneously visible lines
  // Assigns the created repository item to both new columns
  AColumn1->RepositoryItem = ARepositoryItem;
  AColumn2->RepositoryItem = ARepositoryItem;
