Thank you for your feedback.
I agree you have some strong points here and I can understand upgrading to the latest version could be a costly process in terms of time and resources. However our target is constantly refining our products and there are vast improvements between latest version and the one you are currently using. That is why I am recommending to consider moving forward and upgrading your solution. If you decide to do that we are wiling to provide you with required support on any difficulties, which you could encounter.
Nevertheless, I would like to thank you for sharing your work-around for the older version with the community and I am updating your Telerik points for that. Do not hesitate to contact us again if you have any other questions.
