TMS Version 6.4.2.0 , Control Version 1.2.0.1
With 1 TAdvSmoothSpinnerColumn RangeType = rtDateTime, StepType = stMonth or stYear, and Step = 1
Spinner->Colums->Item[0]->Previous(true) Always goes back 2 steps
Spinner->Colums->Item[0]->Next(true) Does nothing
With StepType = stDay it functions well.
With RangeType = rtNumber it functions well
With previous versions of the control it performs well,
Actually not very well because a problem while animating. if you call Next() faster than the control finish with updating , the control turns erratically up or down or not changing at all. same with previous.
