Description dean.mustakinov 2021-06-24 23:53:49 EDT

TeeGrid for Delphi v1.10.

In the "Master_Detail_FireDAC" demo it is not possible to easily expand all child rows.

I have created a convenience method to show or hide all child rows of a row group.

In Tee.Grid.RowGroup.pas: 
  Added public method:
procedure TRowGroup.ShowHideAllDetail(const ACol: Integer; const AShow: Boolean);
var 
    tmpBand : TGridBand;
    r : Integer;
begin
  if Rows.Data = nil then Exit;
  for r := 0 to Rows.Data.Count - 1 do
  begin
    tmpBand:=Rows.Children.Row[r];
    if AShow then begin
      if (tmpBand = nil) or (not tmpBand.Visible) then ToggleDetail(Columns[ACol].Render, r);
    end
    else if (tmpBand <> nil) and (tmpBand.Visible) then ToggleDetail(Columns[ACol].Render, r);
  end;
end;
