B4A Library [B4X] [XUI] AS DatePicker - fast navigate to a Month - Year - Decade - Century | RangeDatePicker

This is a simple DatePicker, with which you can quickly reach your target date. With a click on the header the view changes.

I spend a lot of time in creating views, like this and to create a high quality view cost a lot of time. If you want to support me and further views, then you can do it here by Paypal or with a coffee.

• In the month view, you can select a date
• In the year view, you select a month
• In the decade you see a range of 10 years
• In century you can see 100 years

SelectMode = Range

Make sure you are using ASViewPager V2.01+

[Alexander Stolte]

Can you tell me where I'm wrong?

Yes i can.

dpData.CreateASDatePicker_WeekNameShort

You need to call it this way:

dpData.WeekNameShort = dpData.CreateASDatePicker_WeekNameShort("LU","MA","ME","GI","VE","SA","DO")

dpData.FirstDayOfWeek=6

If you change this, then you need to call:

dpData.Rebuild

And please make a new thread for questions next time, thanks.
