Assigning DisplayMember of a combo box with a value from a Tuple within a list of Tuple - C#

Question

I have a combo box on a windows form that I am trying to populate with a list of clients. I have a List of Tuple with three values (var clients = new List<Tuple<int, string, string>>();) I am getting data from a SQL call returning a clientID, clientName, and path.

The issue I am having is, my combo box is displaying (1, companyName, c:\Path) which is the first value of my list, but what I really want to display is the companyName (Item2 in the tuple) and not the other data.

If my clients variable was just a Tuple instead of a list of Tuple I would be able to do this:

comboBoxClients.DisplayMember = clients.Item2;
comboBoxClients.ValueMember = clients.Item1

Here is the code I tried to use which didn't work:

var clients = new List<Tuple<int, string, string>>();
clients = GetClients();
comboBoxClient.DataSource = clients;
comboBoxClient.DisplayMember = clients[0].Item2;

Is there a way I can set the DisplayMember to the second item of my tuple in the list? Is there something else I should be using instead of a tuple? Any help with this is appreciated.

Try setting comboBoxClient.DisplayMember = "Item2";

DisplayMember should be a string declaring the name of the property to be diplayed. See here: http://msdn.microsoft.com/de-de/library/system.windows.forms.listcontrol.displaymember%28v=vs.110%29.aspx

Handling of ValueMember is the same.
