Is it possible to restrict the selections and shown options to just be the month and year and not show the days?

 

I have set the format to MMMM yyyy - which all works fine, I just do not want the days to show up to select from, just the months and year.

 

I have attached how the picker currently looks, but I do not want the calendar.

 

Thanks in advance.

Hello, Damien,  

The embedded RadCalendar in the RadDateTimePicker's popup has HeaderNavigationMode property, which determines what will be the behavior of the control when the end-users clicks on the header of RadCalendar. I believe that if you set the DateTimePickerElement.Calendar.HeaderNavigationMode to Zoom and handle the ZoomChanging event to restrict zooming down to days, you can benefit the zooming behavior that RadDateTimePicker offers out of the box. 

I have prepared a sample code snippet for your reference. The attached gif file illustrates the achieved result. Now, you can navigate through months and years and easily select the desired month/year: 
        public RadForm1()
        {
            InitializeComponent();  

            this.radDateTimePicker1.Format = DateTimePickerFormat.Custom;
            this.radDateTimePicker1.CustomFormat = "MMMM yyyy";

            this.radDateTimePicker1.DateTimePickerElement.Calendar.HeaderNavigationMode = HeaderNavigationMode.Zoom;
            this.radDateTimePicker1.DateTimePickerElement.Calendar.ZoomLevel = ZoomLevel.Months;
            this.radDateTimePicker1.DateTimePickerElement.Calendar.ZoomChanging+=Calendar_ZoomChanging;
        }

        private void Calendar_ZoomChanging(object sender, CalendarZoomChangingEventArgs e)
        {
            if (this.radDateTimePicker1.DateTimePickerElement.Calendar.ZoomLevel== ZoomLevel.Months && e.Direction == DrillDirection.Down  )
            {
                e.Cancel = true;
            }
        } 

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
