Question

You are asked to create the beginnings of a point of sale system for a bookstore in an .aspx webpage. The manager needs to know how much to charge for a transaction derived from the bookstore's three product categories: magazines, paperback books, and educational toys. Using one .aspx page. This project gives you practice with input validation, using local variables, and reporting your output.

Include input validation as needed.

If each magazine costs $6, each book costs $20, and each toy costs $15, Calculate the price of each product times the quantity of the product sold. The program should use a button click procedure to calculate and display the charge for the transaction. The first textbox shows the amount prior to adding sales tax. The second textbox will display tax amount to be added (use a 8% tax rate). The third textbox will show a list of items ordered and their quantities followed with the total amount charged. For example:

1 Magazine @ $6 = $6.00
1 Book @ $20 = $20.00
2 Toys @ $15 = $30.00
Subtotal = $56.00
Tax = $4.48
Total = $60.48
