i think Xium is right i totally agree with him
look if u have 100 rows then u have to place 100 command button next to each row and it doesnt make any sense to put more command buttons...

u wanna edit selected row right?
then as Xium suggested place one command button and select row which u wanna edit press edit button
or u can use vb.net with datagridview control...
