How to display popup from code-behind in ASP.net?

I wonder how it would be possible to launch a series of popups, containing a form, from code-behind.

I possess a list of objects 'Products'

and I wish I could change one property (quantity) of each "product".

Here's how I build my list (normally I use a开发者_Python百科 database).

Private List<Product> listProduct;


    listProduits = new List<Product>();

    Product objProduit_1 = new Produit;

    objProduct_1.ref = "001";
    objProduct_1.article = "G900";
    objProduct_1.quantity = 30;

    listProducts.Add(objProduct_1);

    ProductobjProduit_2 = new Product;

    objProduct_2.ref = "002";
    objProduct_2.article = "G900";
    objProduct_2.quantity = 35;

    listProduits.Add(objProduct_2);

And I would like displayed popup one after one.

Thank you in advance for your help

you'll need to write some client side code that produces what you're looking for. The AJAX Control tool kit may be along the lines of what you're looking for.
