Listview SelectedIndexChanged

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 customersList = new List();

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

Wow, it works.

Thank you soooo much, there were so many different methods I was trying.

.NET is so huge at the moment for me, I have much to learn but aspire to be a good developer one day.

Kind regards

Assuming the ListView's MultiSelect property is false, I'd try:

private void lstCustomers_SelectedIndexChanged(object sender, EventArgs e)
{
if (lstCustomers.SelectedItems.Count == 1)
{
int customerId = int.Parse(lstCustomers.SelectedItems[0].Text);
// fetch data for that customer
}
}
