Listview SelectedIndexChanged

Question

Hi I am a newbie to C#, my current problem is how to use the selectedindexchanged property of a listview.

Basically I have a listview that is bounded on page load to the Customers table in the db.
What I am trying to achieve is when I select a specific customer on the listview, it should fetch data from the database for that specific customer and populate the textboxes so I can modify details.

I am programming using 3 tier procedures.

Any help would be appreciated. I basically want something like this int CustomerID = lstCustomers.selected????.value

So that I can pass the customer ID into another method and retrieve details.

my code is below:

    private void GetCustomerList()

        {

            List<Customer> customersList = new List<Customer>();

            try

            {

                customersList = CustomersDB.GetCustomers();

                if (customersList.Count > 0)

                {

                    Customer customer;

                    for (int i=0; i < customersList.Count; i++)

                    {

                        customer = customersList[i];

                        lstCustomers.Items.Add(customer.CustomerID.ToString());

                        lstCustomers.Items[i].SubItems.Add(customer.FirstName.ToString());

                        lstCustomers.Items[i].SubItems.Add(customer.LastName.ToString());

                        lstCustomers.Items[i].SubItems.Add(customer.DateJoined.ToShortDateString());

                        lstCustomers.Items[i].SubItems.Add(customer.Telephone.ToString());

                        lstCustomers.Items[i].SubItems.Add(customer.Email.ToString());

                    }

                }

                else

                {

                    MessageBox.Show("No customers exist in the database");

                    this.Close();

                }

            }

            catch (Exception ex)

            {

                MessageBox.Show(ex.Message, ex.GetType().ToString());

                this.Close();

            }

        }

        private void lstCustomers_SelectedIndexChanged(object sender, EventArgs e)

        {

        }

Thanks for any help
