"I am Software Engineer at CAS Germany. We recently decided to purchase the Smart PropertyGrid instead of developing such a control by ourselves. We were looking after a PropertyGrid having some additional features the MS PropertyGrid was not able to provide us. First we had some reservations to purchase such a piece of software from a one person company but soon it showed that this was not a mistake. After we started to integrate the SPG into our software it soon showed up that the SPG was not 100% compatible with the WeakReferences we use to assure the cleanup of some large Objects. So i contacted the Developer of the SPG, Nicolas Cadilhac, to get support to this problem. Instead of waiting several days for some answers he responded to my Mails in less than one hour. He immediately started to realize what the problem was and developed a new release of the SPG for us at the same day. This i am calling support. Thank you again, Nicolas! Great piece of software, great support!"
