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:

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;
