I need a combobox that supports selecting multiple items, preferably with checkboxes. I can't find an example of how to do this. Does your control support it
// CellStateChanged event - Fired after cell's state has been changed.
procedure TForm1.ComboBox1CellStateChanged(ASender: TObject; Cell : HCELL);
begin
with ComboBox1 do
begin
LabelText := Cell;
OutputDebugString( Items.CellCaption[OleVariant(0),OleVariant(Cell)] );
OutputDebugString( Items.CellState[OleVariant(0),OleVariant(Cell)] );
end
