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.
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.
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.
