Thank you for the feedback.
Indeed, due to the flexibility and the unique visual appearance that our controls provide, there are some performance penalties, when compared to the Standard Windows Forms Controls. We have always tried to avoid this tradeoff of performance versus visuals and will continue doing so.
Generally, I understand your arguments. However, if you decide to give our suite a chance, we will help you as much as we can in optimizing your application's work with our controls.
If you have questions or feedback to share, feel free to contact me.
All the best,
the Telerik team
