TdxListViewItemEvent Type

The procedural type for list item action handlers.

Declaration

TdxListViewItemEvent = procedure(Sender: TdxCustomListView; AItem: TdxListItem) of object;

Parameters

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

Remarks

The following OnDeletion event handler clears the control’s selection when a node is deleted:

Delphi

procedure TForm1.dxListViewControl1Deletion(Sender: TdxCustomListView;
  AItem: TdxListItem);
begin
    Sender.ClearSelection;
end; 

C++

void __fastcall TForm1::dxListViewControl1Deletion(TdxCustomListView *Sender,
  TdxListItem *AItem)
{
  Sender->ClearSelection();
}

The List View’s OnInsert and OnDeletion events reference the TdxListViewItemEvent type.
