文本输入框电源应用程序中的日期和时间验证

Question

Good day. I have created a new power app: In the application one of the text input field user will update date and time values Ex format: 29/12/2022 10:30 AM

Before saving the data I need to validate the format like (DD/MM/YYYY HH:MM AM/PM).

Could you please some one help if user entered the wrong format need through error message or highlight the field.

Answer 1

This approach may not be the best UX. It could cause users to try multiple times until they get it right.

Why not use a datepicker with dropdowns for hours, minutes and seconds? You could then combine the inputs into a datetime value and format it as required using Text(). The necessity to validate formats is elimated.

Answer 2

Try this code in OnChange property of the text box.

If (.IsMatch(TextInput1,Text:"\d{2}/\d{2}/\d{4} (1[0-12][1-9]),[0-5][0-9] ([AaPp][Mm])" ): Notify("Please enter DD/MM/YYYY 00,00 AM/PM Format". NotificationType;Error);Reset(TextInput1) )

Output: If you enter correct format( 01/02/2023 11:00 AM) it wil move to next field otherwise displays a notification error.
