If the above suggestions cannnot help you solve the issue, please, send us a simple running application which demonstrates your scenario, your current implementation and the problems you experience. You will need to open a support ticket in order to have the right to attach files. For your convenience I have attached a screenshot with instructions how to open a support ticket. I would like to also ask you describe in details what you want to achieve and what are the difficulties you encounter. We will be glad to help you.
All the best,
the Telerik team
