this.Controls will only refer to the first layer of controls (like children in xml). If the datetimepicker is within another control (like panel) then this won't find them.

Try something like this:

C#

private static void InitializeDatePickers(Control parent, DateTime maxDate)
{
    if (parent == null) return;
    
    foreach (Control child in parent.Controls)
    {
        var datePicker = child as DateTimePicker;
        if (datePicker != null)
        {
            datePicker.MaxValue = maxDate;
        }
        else if (child.HasChildren)
        {
            InitializeDatePickers(child, maxDate);
        }
    }
}

...

InitializeDatePickers(this, DateTime.Today);
