Answer 1

Sure you can. The trick here is to know that ListBox (and CheckedListBox) contain a list of Objects. It uses the ToString method of those objects to display. All you have to do is populate the list with your own type which has a ToString override.

using System;
using System.Drawing;
using System.Windows.Forms;

public class Form1 : Form
{
    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new Form1());
    }

    public Form1()
    {
        Controls.Add(new Label { Text = "Name", Location = new Point(10, 10), AutoSize = true });
        Controls.Add(new TextBox { Name = "Name", Location = new Point(60, 10) });
        Controls.Add(new Label { Text = "Date", Location = new Point(10, 40), AutoSize = true });
        Controls.Add(new DateTimePicker { Name = "Date", Location = new Point(60, 40) });
        Controls.Add(new Button { Name = "Submit", Text = "Submit", Location = new Point(10, 70) });
        Controls.Add(new CheckedListBox { Name = "List", Location = new Point(10, 100), Size = new Size(ClientSize.Width - 20, ClientSize.Height - 100 - 10) });
        Controls["Submit"].Click += (s, e) =>
                (Controls["List"] as CheckedListBox).Items.Add(new MyItem { Name = Controls["Name"].Text, Date = (Controls["Date"] as DateTimePicker).Value });
    }
}

public class MyItem
{
    public string Name { get; set; }
    public DateTime Date { get; set; }

    public override string ToString()
    {
        return String.Format("{0} {1}", Name, Date);
    }
}
