Hi,

I am assuming you are referring to a "Repeating Table" and not a "Repeating
Section" as you indicated you need "each and every row" to be locked
separately.

If this is the case, you will need to modify your design such that you add
a button for each row in the table that, as an example, toggles a check box
field to True. Then you can set Conditional Formatting for each control
where it gets set to Read Only when the check box is true.

There is really no way to use one button outside of the Repeating Table
because as soon as you click that button, focus is lost from the row/field
you were on so there is no way to determine what row needs to be locked.

If you don't like the button for each row idea, you may be able to use a
Rule or code on a specific field whereas once that field gets completed, it
sets the check box to True.

I hope this helps!
