Generally we set the primary key values to the datakeyName property in gridview control and below code will help to get that date key values associated with a row in rowdatabound event.

protected void gv1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                string userID = gv1.DataKeys[e.Row.RowIndex].Values[0].ToString();
            }
        }
