Change condition when combobox is used

Currently using C# in Visual Studio 2013 make a program where I want something on the screen to become available once the user has selected any value from a combobox. So far I have made this: 

        if (cmbTickets.SelectedIndex == 10)
        {
            enableSeats();

        }

When this is used the item on the screen becomes available only when the number ten is chosen from the combobox. I wan this to happen however when any of the options in the combobox is selected. What value should I place in the if statement to do this?

Subscribe to the SelectedIndexChanged event.

The SelectedIndex is -1 when no selection has been made, so just reference that.

private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
    if (comboBox1.SelectedIndex > -1)
        enableSeats();
}
