Hey your binding only Current row again and again, should you bind like dgpersonal.Rows[i].Cells[0].Value http://tutorpinoy.blogspot.com/2014/04/populate-data-into-datagridview-csharp.html?m=1

That's what I am telling you the movement datagridview binds in form load event automatically row added event will trigger so only i am suggesting to keep decrypting part at row added event otherwise call datagridview bind function then call decrypt function. Please post your form load code
