So in same page i added insert, delete & update record.
I have placed on right places i gues. When product is added, insert records works & also update record gets updated. but when i try to delete a product from the same then update record doesn't work.
Insert behaviour is using trigger as per button.
Delete behav is using trigger as per delete button
& Update is using on "any form post"
But doesnt update when delete behav is hit.
