Using Vs 2015 and having no luck binding a DateTimePicker control. The easiest thing seems to be simply not binding it- handle passing the value of your object to the control and from the control to your object manually. A few lines of code will save you lots of headaches...

private void BindData()
{
    // can't bind the datetimepicker, so handle it manually...
    if (o.myDate == null)
    {
        dtDatePicker.Checked = false;
    }
    else
    {
        dtDatePicker.Checked = true;
        dtDatePicker.Value = o.myDate.Value;
    }
}

private void Save()
{
    if (dtDatePicker.Checked)
    {
        o.myDate = dtDatePicker.Value;
    }
    else
    {
        o.myDate = null;
    }
}
