missing row in datagrid

for some reason i am missing a row in the datagrid; the row is present in the table.

first i have a method which inserts multiple rows in the table using the 'insert into' so the first row that is intserted is actually at the bottom of the table. then when displaying the data in a datagrid i dont see the first record inserted (ie the last row)

in design view if i choose to preview data in the datagrid then i see ALL the rows.

any ideas?

thanks
