please see mean row below have selected dont no comming thanks

the blank row added automatically if have allowusertoaddrows property set true on datagridview control.

from documentation:

if datagridview bound data, user allowed add rows if both property , data source's ibindinglist.allownew property set true.

on separate note, shouldn't have create anew binding source (for source data grid). instead, modify collection bound datasource property.
