Hi, For the GridViews RowDeleting event, access the ID and remove it. Here is the steps to follow. After successful deletion re-bind the list to the GridView control. 1. For the delete button, set CommandArgument as the ID. /> 2. For the RowDeleting event. protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e) { Button btnDelete = (Button)GridView1.Rows[e.RowIndex].FindControl("btnDelete"); if (btnDelete != null) { int iProductID = Int32.Parse(btnDelete.CommandArgument); if (Session["lstProduct"] != null) { List lstProducts = (List )Session["lstProduct"]; Products oProducts = lstProducts.Find(delegate(Products p) { return p.product_id == iProductID; }); if (oProducts != null) { //Give a message : record deleted successfully. lstProducts.Remove(oProducts); Session["lstProduct"] = lstProducts; GridView1.DataSource = lstProducts; GridView1.DataBind(); } } } } Hope it helps, Thx, Gayani

Products oProducts = lstProducts.Find(delegate(Products p)

what is delegate?I did't use product class.here is my code:

if (Session["basket"] == null)
{

                List pid = new List();
                pid.Add(productid.Trim());

                Session\["basket"\] = pid;
            }
            else
            {
                ((List)Session\["basket"\]).Add(productid.Trim());
            }

Button btnDelete = (Button)GridView1.Rows[e.RowIndex].FindControl("btnDelete");

I don't have RowIndex in my smart list.
