Hi,

I am trying to load data from a webservice into a public List<> which represents a data class, i need the data available to the page, but its not always displayed .

I want to be able to query the List<> so i can edit values also, add, delete this data after the initial load, should i be using List or doing it another way for instance, ArrayList.

if list is correct, is there any good examples of how go about this, as i havent found any where i can query the list and edit values, hence i am wondering if I am doing this correctly

public class dataBubs
    {
        public Guid         guid_id { get; set; }
        public string       bubName { get; set; }
        public string       bubDesc { get; set; }
        public int          plan_id { get; set; }
        public int          visability_id { get; set; }
        public string       docLink { get; set; }
        public string       colour { get; set; }
        public DateTime     saved_datetime { get; set; }
        public Guid         template_pran_id { get; set; }
        public int          role_id { get; set; }
        public string       pran_type { get; set; }

        public List bubAll { get; set; }

    }

you could use a Dictionary

public class DataBubs
    {
        public Guid guid_id { get; set; }
        public string bubName { get; set; }
        public string bubDesc { get; set; }
        public int plan_id { get; set; }
        public int visability_id { get; set; }
        public string docLink { get; set; }
        public string colour { get; set; }
        public DateTime saved_datetime { get; set; }
        public Guid template_pran_id { get; set; }
        public int role_id { get; set; }
        public string pran_type { get; set; }

        public DataBubs(string name)
        {
            bubName = name;
        }
    }

static void Test1()
        {
            // assuming name is unique
            Dictionary dataBubsCollection = new Dictionary();

            DataBubs dataBubs1 = new DataBubs("al");
            dataBubs1.bubDesc = "bubs 1";

            DataBubs dataBubs2 = new DataBubs("jan");
            dataBubs2.bubDesc = "bubs 2";

            dataBubsCollection.Add(dataBubs1.bubName, dataBubs1);
            dataBubsCollection.Add(dataBubs2.bubName, dataBubs2);

            Console.WriteLine(dataBubsCollection["jan"].bubDesc); // this sill return bubs 2
        }
