how ArrayList To change a value

Let me explain you what I understood so far. You have an arraylist. You fill this array list with the session value. From this array list you want to update an item? What is the type of the arraylist? "CShoopingCartItem"?

Saeed, it does not make any sense actually. I kindly ask you to try to describe your problem more clearly.

ArrayList items = (ArrayList)Session["mycart"];
CShoppingCartItem item = new CShoppingCartItem();
ImageButton btn = (ImageButton)sender;
string[] CommandArgument = btn.CommandArgument.Split(',');
idbookbuy =Convert.ToInt32(CommandArgument[0]);
txtnamee = CommandArgument[1];
txtName = CommandArgument[2]; Session["mycart"] = arr;
item.ProductName = txtName;
item.ProductNameE = txtnamee;
item.UnitPrice = decimal.Parse(CommandArgument[3]);
item.Quantity = 1;
item.idbook = idbookbuy;
arr.Add(item);

Solution 2

Instead of ArrayList , I think it is more suitable for you to use a List<t> here. Change it to

C#

List<cshoppingcartitem> items = new <cshoppingcartitem>();

add your items to that list. When you want to update an item loop through the list and find the item and update it.

C#

foreach(CShoppingCartItem cItem in items)
{
  if(condition)
  {
    item.inquntity = 2;
  }
}
