Hi @shine_d,
Thanks for your detailed case description.
Please offer me more information.
1. Do you want to display the data of Timestamp which has been submitted use the form?
2. How do you set your Item property of the edit Form?
3. Do you want to refresh the Timestamp and submit the current time to the DataSource?
I have tested according to your requirements.
If you want to display the submitted data and refresh it to the current time.
Please try:
1. Set the Item property of edit Form as:
Gallery1.Selected
2. Set the On Select property of Button as:
UpdateContext({Timestamp:Text(Now(),"dd/mmm/yyyy hh:mm AM/PM")})
3. Set the Default property of DataCardValue as:
If(Timestamp = Blank(), ThisItem.DateField,Timestamp).
Note that the DateField represents the field you save the date time in your SP list.
Best Regards,
Kyrie Zhang
