Description yeray alonso 2015-03-02 06:59:44 EST

A customer is trying move a TChart to a TQRChart.
If I do this I get an error saying "TabOrder not found":

var tmpStream: TMemoryStream;
begin
  tmpStream:=TMemoryStream.Create;
  SaveChartToStream(Chart1, tmpStream);

  tmpStream.Position:=0;
  LoadChartFromStream(TCustomDBChart(QRDBChart1), tmpStream);
  QRDBChart1.Parent:=QuickRep1;

Using CloneChart works fine.

TabOrder cannot be made published in TQRChart or TQRDBChart.
For this property (and also any other properties not supported by QR controls), using LoadChartFromStreamCheck solves the problem.

function TForm1.SkipErrors(const Message: string): Boolean;
begin
  result:=True; // <-- True means: continue reading, ignore the exception(s)
end;

...
  LoadChartFromStreamCheck(TCustomDBChart(QRDBChart1), tmpStream, SkipErrors);


"SkipErrors" is a local function that returns True to avoid the exception and continue loading the chart.

Note: Running inside the IDE with debugging will still stop the application when the exception happens, pressing F9 (run) again will continue as expected.

Running "without debugging" will not stop at all.
