Hi,

There's no Month + Year only functionality in either of these controls.

And the UltraCalendarCombo doesn't natively support hiding the DropDownButton. But it can be done using a CreationFilter.

    public class NoDropDownButtonCreationFilter : IUIElementCreationFilter
    {

        #region IUIElementCreationFilter Members

        void IUIElementCreationFilter.AfterCreateChildElements(UIElement parent)
        {
            if (parent is CalendarComboEditorUIElement)
            {
                UIElement calendarDropDownButtonUIElement = parent.GetDescendant(typeof(CalendarDropDownButtonUIElement));
                UIElement editorWithTextUIElement = parent.GetDescendant(typeof(EditorWithTextUIElement));

                // Remove the dropdown button. 
                parent.ChildElements.Remove(calendarDropDownButtonUIElement);

                // Set the Rect of the EditorWithTextUIElement to fill the empty space left by the button.
                editorWithTextUIElement.Rect = parent.RectInsideBorders;                
            }
        }

        bool IUIElementCreationFilter.BeforeCreateChildElements(UIElement parent)
        {
            // Do nothing
            return false;
        }

        #endregion
    }

It is still possible to toggle the dropdown via the keyboard, though. So you will need to handle that by modifying the KeyActionMappings.

        private void Form1_Load(object sender, EventArgs e)
        {
            this.ultraCalendarCombo1.CreationFilter = new NoDropDownButtonCreationFilter();

            KeyActionMappingBase[] kams = new KeyActionMappingBase[this.ultraCalendarCombo1.KeyActionMappings.Count];
            this.ultraCalendarCombo1.KeyActionMappings.CopyTo(kams, 0);

            foreach (KeyActionMappingBase kam in kams)
            {
                if (kam.ActionCode is CalendarComboAction)
                {
                    if ((CalendarComboAction)kam.ActionCode == CalendarComboAction.ToggleDropDown)
                    {
                        this.ultraCalendarCombo1.KeyActionMappings.Remove(kam);
                    }
                }
            }
        }
