Before you buy someting I think its useful for you to have the possibility to test my libraries if they are good enough for you.
All trial libraries listed here are build with the .net Framework 4.0 and AnyCPU with the full functionality.
(The trials are not intended to be used for deploying with other applications. A trial dialog is showing up once at runtime for each assembly.)
The trial libraries
 full functionality without limitation of time,
 get full support from me and
 are always the latest available version
Enhance your WPF with 20+ new Controls and 9+ additional behaviours
Everybody who develops applications knows that in the .Net framework some controls are just missing. You maybe would like to have a simple NumberBox or a TreeListView, but such controls are not available build-in.

Or you would like to have more functionalities on your existing WPF controls.

The DW.WPFToolkit fills up these gaps, as soon you want to solve a problem or you just need a better control you should have a look into this library.
