Solution 1

for finding cell values of that row you need to find container row of button first.

See THIS[^] will surely help you.

[update]

As you now got object of GridViewRow(grdRow) from linked article.

you could further investigate like below to find datakey on Button click event

GridViewName.DataKeys[grdRow.RowIndex].Value.toString();

you do not need to loop through each row if button is present for every row.
