Combobox and a textbox

Hi thanks for the reply, i have added some more code around the combo box control which i think should take the event(s)and populate the combo box with the data but i do not seem to be able to retrieve any info, any help would be great.thanks
//creating the community events list.
List<community_event> CommnunityEvents;

//create the Create Event list method.
private void CreateEventList()
{
CommnunityEvents = new List<community_event>();
// call the extract Data method.
ExtractData();
eventComboBox.Items.Clear();
foreach (Community_Event item in CommnunityEvents)
{
eventComboBox.Items.Add(item.Description);
}
if (CommnunityEvents.Count > 0)
{
//if there are no events for the date selected display the following
eventComboBox.Text = " -Events- ";
descriptionTextBox.Text = "Pick an event";
}
else
{
//if there are no events for the date selected display the following
eventComboBox.Text = " No Events ";
descriptionTextBox.Text = "No events today.";
}

}
//Assignment 4 Part 2 – Create Method ExtractData
private void ExtractData()
{
CommnunityEvents.Clear();

// load the data from the file
List<community_event> tempList = new List<community_event>();
//string[] fileLines = File.ReadLines(@"C:\Users\IAN\Documents\calendar.txt");

foreach(string line in File.ReadLines("Calendar.txt"))
{
string[] items = line.Split(",".ToCharArray());
if (items.Length >= 5)
{
Community_Event newEvent = new Community_Event();
newEvent.Day = Convert.ToInt32(items[0]);//Converting the Integer to a string.
newEvent.Time = items[1];
newEvent.Price = Convert.ToDecimal(items[2]);//Converting the decimal to a string.
newEvent.Event = items[3];
newEvent.Description = items[4];

CommnunityEvents.Add(newEvent);
}

}
CommnunityEvents = (from ev in tempList
where ev.Day == 1
select ev).ToList();
}

private void dateMonthCalendar_DateChanged(object sender, DateRangeEventArgs e)
{
//calling the create event list method to display any events in the eventscombo box.
CreateEventList();
}

private void eventComboBox_SelectedIndexChanged(object sender, EventArgs e)
{
/*display time, price and desription of any events selected in the combo box and display them
in the description TextBox*/

}
private void descriptionTextBox_TextChanged(object sender, EventArgs e)
{

}
private void TicketInformationForm_Load(object sender, EventArgs e)
{
//calling the create event list to open the form with today's events displayed if any.
