Chandra X-ray observations revealed powerful relativistic outflows associated with the AGN activity. Large scale X-ray jets extend to more than >100 kpc distances from the nucleus of a host galaxy. They indicate a long-term evolution of a powerful radio source and the importance of both, jets and radio source, interactions with the environment on many different physical scales. They also show that the feedback process linked to a radio mode activity of a central black hole happens at all redshifts. I discuss results of X-ray studies of a sample of compact radio sources. These sources can represent the first stage of the radio source growth. They are contained within their host galaxy and interact strongly with the dense ISM. Although X-rays can provide information about the source interactions with the ISM and feedback process they could not be observed in X-ray due to limited sensitivity of the earlier missions. I discuss a possible evolutionary track of compact radio sources into FRI/FRII large scale source. I also present a luminous radio-loud quasar that is located in the center of an X-ray cluster at z~1 and discuss the constraints on the radio source evolution given by this observation.
