How to view all data in the database to specific text boxes

Question

I created a database named sbill.

It contains fields like billno, date,amount, particulars, quantity, name.

I created a datagrid view and displayed billno, date, amount. and also added a button named view to each row in gridview.

I want to display all the fields in the database to specific textboxes when clicking on the view button in that row. only the contents of clicked row should be shown in the textboxes.

Pleas help me...
