public static bool Insert(Products product)
        {
            string connString = @"Data Source=ps201\SQLEXPRESS;Initial Catalog=E-commerce;Integrated Security=True;Pooling=False";
            SqlConnection con = new SqlConnection(connString);
            con.Open();
            SqlCommand com = new SqlCommand();
            com.Connection = con;
            com.CommandText = string.Format("insert into Products(Name,Price,ImageUrl,Detail,ProductCode,Item,CategoryID) values('{0}','{1}','{2}','{3}','{4}','{5}','{6}','{7}')",product.Name,product.Price,product.ImageUrl,product.Detail,product.ProductCode,product.Item,product.CategoryId);   //error
            int rowAffected = com.ExecuteNonQuery();
            con.Close();
            if (rowAffected > 0)
                return true;
            else
                return false;
