TdxListViewColumnClickEvent Type

The procedural type for list column click handlers.

Declaration

TdxListViewColumnClickEvent = procedure(Sender: TdxCustomListView; AColumn: TdxListColumn) of object;

Parameters

Name	Type	Description
Sender	TdxCustomListView	The List View control that raised the click event.
AColumn	TdxListColumn	The target list column.

Remarks

The List View’s OnColumnClick event handler below inverts the sort order:

Delphi

procedure TForm1.dxListViewControl1ColumnClick(Sender: TdxCustomListView;
  AColumn: TdxListColumn);
begin
  if AColumn.SortOrder = soAscending then
    AColumn.SortOrder := soDescending
  else
    AColumn.SortOrder := soAscending;
end; 

C++

void __fastcall TForm1::dxListViewControl1ColumnClick(TdxCustomListView *Sender,
  TdxListColumn *ANode)
{
  if (AColumn->SortOrder == soAscending)
    AColumn.SortOrder = soDescending;
  else
    AColumn.SortOrder = soAscending;
}

The List View’s OnColumnClick event references the TdxListViewColumnClickEvent type.
