Previously i had to select data from sqlite but there is no change to the data. So i decided to import excel sheet to form1 datagridview with a qty column set to zero.

On change of qty i want those rows to copy to form 2 datagridview

This is the excel file data to import.

prodcode	product	pack	qty	price	disc	vatamt	total
1234	soap	5	0	15.00	15
4567	towel	1	0	27.00	15

however i have managed to do this and will appreciate it if you would assist in solving how to get it to excel file with subtotals and vat.

please check my code if it needs updating.
