TdxListViewEditedEvent Type

The procedural type for list item caption change handlers.

Declaration

TdxListViewEditedEvent = procedure(Sender: TdxCustomListView; AItem: TdxListItem; var S: string) of object;

Parameters

Name	Type	Description
Sender	TdxCustomListView	The List View control that raised the event.
AItem	TdxListItem	The target list item.
S	string	The edited item caption.

Remarks

The following OnEdited event handler discards changes made in an in-place editor if a user assigns an empty string to an item caption:

Delphi

procedure TForm1.dxListViewControl1Edited(Sender: TdxCustomListView;
  AItem: TdxListItem; var S: string);
begin
  if S = '' then
    S := AItem.Caption;
end;

C++

void __fastcall TForm1::dxTreeViewControl1Edited(TdxCustomListView *Sender,
  TdxListItem *AItem, UnicodeText &S)
{
  if (S == "")
    S = AItem->Caption;
}

The List View’s OnEdited event references the TdxListViewEditedEvent type.
