TdxListViewSelectItemEvent Type

The procedural type for list item selection handlers.

Declaration

TdxListViewSelectItemEvent = procedure(Sender: TdxCustomListView; AItem: TdxListItem; ASelected: Boolean) of object;

Parameters

Name	Type	Description
Sender	TdxCustomListView	The List View control that raised the event.
AItem	TdxListItem	The target list item.
ASelected	Boolean	The item’s selection state.

Remarks

The following OnSelectItem event handler prohibits a user from selecting an item:

Delphi

procedure TForm1.dxListViewControl1SelectItem(Sender: TdxCustomListView;
  AItem: TdxListItem; ASelected: Boolean);
begin
  if ASelected then
    AItem.Selected := False;
end;

C++

void __fastcall TForm1::dxListViewControl1SelectItem(TdxCustomListView *Sender,
  TdxListItem *AItem, bool &ASelected)
{
  if (ASelected)
    AItem->Selected = false;
}

The List View’s OnSelectItem event references the TdxListViewSelectItemEvent type.
