I LOVE component suites !
I regularly use web components from Infragistics, Telerik, ComponentOne, Dundas, eXceed, and others.
I recently tool PureComponents Ultimate Suite for a Spin !
The first thing that struck me ........
The Price = $79
Need the source code ? It's only another $60 !
It includes controls for Calendars, Lists, Navigators, a Ribbon UI, and about every input control you can think of.
For the price, you really can't beat it.
