How to bind session data to gridview for shopping cart

Question

I am not sure is this a best way but i am storing shopping cart data in Dictionary. I would like to bind data to gridview and use in aspx page.

Somehow, can we use <%# Eval("product_id") %> in gridview in aspx page?

Set Dictionary

public Dictionary<int, Product> products = null;

Cart:

products = new Dictionary<int, Product>();

Reading data with this code:

Cart mycart = (Cart)Session["activecart"];
            double GeneralTotal = 0; 
            foreach (int i in mycart.products.Keys)
            {
                Response.Write(mycart.products[i].product_id);
                Response.Write(mycart.products[i].product_name);
                Response.Write(mycart.products[i].product_price);
                Response.Write(mycart.products[i].product_quantity);
                Response.Write(mycart.products[i].total_price);
                GeneralTotal += mycart.products[i].total_price;
            }
            Response.Write(GeneralTotal);

I can read values using foreach but i want to show those data in gridview using Eval.

I have tried this code to bind gridview:

Cart activeCart = (Cart)HttpContext.Current.Session["activecart"];
gridview1.DataSource =  activeCart.products;
gridview1.DataBind();

This is only getting key, value variable from dictionary. Couldn't get specific values using <%#Eval("custom") %>. Any suggestion?

Answer 1

I would do it like this:

Cart mycart = (Cart)Session["activecart"];
double GeneralTotal = 0; 

DataTable tempBasket = new DataTable();
DataRow rowTempBasket;
tempBasket.Columns.Add("product_id", typeof (int));
//Add the other columns  the same way

foreach (int i in mycart.products.Keys)
{
     rowTempBasket = tempBasket.NewRow();
     rowTempBasket["product_id"] = mycart.products[i].product_id;
     //Add the other columns the same way

     tempBasket.Rows.Add(rowTempBasket);
}

//Then DataBind the created table to your GridView
gridview1.DataSource = tempBasket; 
gridview1.DataBind(); 

Then you should be able to use Eval.

EDIT

Maybe you post the code of your ASPX page. Would help what to do about the Total.
