I am using a dateTimePicker control in a windows app using c#. I am only interested in getting & passing on the month & year, so I have enabled the up/down buttons, and I use a custom format to display the month & year (MMMM '-' yyyy). It works great functionally - does exactly what I want. However, when it displays the month and year (like this: March - 2011) it piuts a blue background (highlight) around the month name. Although it works perfectly, it looks very odd. Clicking or double-clicking on the highlighted month name has no effect - the contents are read-only. There are a number of properties associated with color for the control (CalendarForeColor, CalendarMonthBackground, etc) but they have no effect - probably because I'm actually disabling the calendar part. I have also tried setting them in code, again, with no effect.
Not a huge deal, the thing still works, after all, but it would look a lot better if I could disable or control this background highlighting.
