Disclaimer: Infragistics contacted me and asked me to do a review of one of their products. They also paid me, thank you to them . I had trouble creating an account, so I fired up their chat support and they fixed it for me in a few minutes. That was a great start after the initial frustration with their registration system. http://www.infragistics.com... http://www.infragistics.com...
