hi.
i am trying to do a shopping cart project where whenever u add some product to the cart i will store in a session array with 3 variables. its a spectacle shop so.3 things are to be added into array is pid,total no of amount and lens type.bt that's not the big issue.
I have done the part to add the product details into an array. and showing the array in a dynamically created array. here in the table whenever its showing the details its created a delete button. now i have stuck to delete the product details from session whenever user click a particular button to delete a product from cart.
webapplication1 --->> here i am adding the details in 3 textboxes. and in webapplication2 its showing the array along with the delete button..
and the array is created in the cart.cs
