| Summary | 0003973: JvMemoryDataset, troubles with .RecNo | ||||
| Description | 1) SetRecNo method should call *Scroll events. Look at TBDEDataSet.SetRecNo or TClientDataSet.SetRecNo Thus it is better to like like that: ~~~~~ procedure TJvMemoryData.SetRecNo(Value: Integer); begin if (Value > 0) and (Value <= FRecords.Count) then begin DoBeforeScroll; // Arioch FRecordPos := Value - 1; Resync([]); DoAfterScroll; // Arioch end; end; ~~~~~ 2. Seems like UpdateCursorPos is not to be called from GetRecNo, ro some of routines it calls is implemented wrong, i didn't got ends together yet. So it is to be done yet. | ||||
| Steps To Reproduce | About item 2: Just make a DBGrid to JvMemoryDataset dataset let consists of integer field and string calcfield, that is calculated to InToStr of field1 and one more statement in OnCalcFields let be "Self.Tag := JvMemoryDataSet1.RecNo" - seems like NOP, yes ? then make a button to do JMDS1.EmptyTable; for i := 1 to 10 do JMDS1.AppendRecord([i]); After that just focus the grid and press up/down to run through records. Something very cursed is happening to record buffers !!! | ||||

true. I vote for checking in fix .SetRecNo, and then marking the rest of the ticket - duplicate of 0003461 |
