Thank you for your question.
The controls in the Telerik UI for WPF support touch based on an internal framework we've implemented. More information on the topic is available in the Touch Support article
in the documentation. The article also contains a list of the controls that exhibit "special" behavior with some of the gestures.
My suggestion to you is to try this out and see how it fits your needs. If you encounter any problems related to touch, feel free to get back to us.
