You can use buttons and validation groups

Just give each row its validation group and it should work

It's a button. i would like to add more information here. each row has the same validation not a different validation on each row.
and also, we have one more button called "Edit All" when user click that user able to edit the entire grid and we provided the submit button to save the data. the same validation is validated when submit button is clicked.

so in this case, can you please guide me how to incorporate validation group. do we need to have 2 validation groups?

The validation group can be put in the button in each row.

I guess that you are creating each row with an a!forEach gridRowLayout i guess, right?

You can add for each field with validation also the validationGroup: "group"&fv!index or something similar to uniquely identify the row validation. This validation group name is to be used also in the "Save single row" button.

On the save all no validation group should be provided, this will validate all the information togheter
