[newbie] In Calendar, how to select more than a week range? How to get selected range?

Hello,

I have only basic knowledge of SharpDevelop, and need to simply display a calendar so that I can select a multi-day range and turn into a list like this:

Tue 4 July
Wed 5 July
etc.

After installing SharpDevelop 4.4.2*, I notice that by default, the calendar only supports selecting up to one week: How to remove this limit? And how to turn the selected range into a list of days?

Thank you.

* apparently, release 5 doesn't support VB
