Hi Venkateshweran, thank you for sharing this ! After implementing, the first option, it works as expected by getting or setting null values. I noticed however that this UI has sometimes a funky reaction, it might be worthwhile to take a look. Sometimes, I try to set a value and when I navigate to other controls (standard WIN textbox & combo), then I notice that either the value is not kept or it resets by itself to a null value.
Meanwhile, I havent tried your 2nd option, but came up with a 3rd option, by the use of ComboDropDown on which I assign a MonthCalendarAdv (https://www.syncfusion.com/kb/1333/is-there-a-way-to-configure-datetimepickeradv-so-that-date-entry-is-consistent-with-the-grid-cell)
DateTImePicker1.PopupControl = MonthCalendarAdv1
DateTmePIcker1.PopupControl.Height = 150
DateTimePicker1.PopupControl.Height = 150
I like the look & feel for this 3rd option, however on this, it seems I cannot pickup the date value, and the width of the calendar seems to be dependent of the control, even if I assign it as shown previously
this.comboDropDown1.DropDownWidth = 213;
