Date Picker

A fully custom date picker built from raw PA controls — no native DatePicker control. Features a trigger button with a calendar icon, an inline calendar panel with month navigation, and a 42-cell grid gallery (WrapCount=7). Variables: varDPOpen, varDPViewDate, varDPSelectedDate, varDPFirstDay. Initialize on Screen.OnVisible: Set(varDPOpen,false); Set(varDPViewDate,Today()); Set(varDPSelectedDate,Blank()); Set(varDPFirstDay,Date(Year(Today()),Month(Today()),1)).
