I can't see a good reason why the DateTimePicker is limited to dates after 01/01/01753.

public partial class DateTimeTextBox : UserControl
{
    private DateTime m_value = DateTime.MinValue;

    public DateTimeTextBox()
    {
        InitializeComponent();
    }

    public DateTime Value
    {
        get
        {
            return m_value;
        }
        set
        {
            m_value = value;
            textBoxDate.Text = m_value.Date.ToShortDateString();
        }
    }

    private bool ValidateDate(string date, out DateTime validatedDate)
    {
        validatedDate = DateTime.MinValue;
        DateTimeConverter dtc = new DateTimeConverter();
        try
        {
            validatedDate = (DateTime)dtc.ConvertFromString(date);
        }
        catch
        {
            return false;
        }

        return true;
    }

    private void textBoxDate_Leave(object sender, EventArgs e)
    {
        TextBox textbox = (TextBox)sender;

        if (textbox != null)
        {
            bool validDate = ValidateDate(textbox.Text, out m_value);

            if (!validDate)
            {
                MessageBox.Show("Invalid date");
                textbox.Focus();
            }
        }
    }
}
