Question

mention any two way of propagation of dhamma by the ashoka?

Answer 1

Asoka took many steps for the propagation of Buddhism. First of all Askoa Propagated Dhamma among his subjects by showing them spectacles of the various classes of gods, their heavenly palaces, celestial elephants, etc. These were shown in different 'Samajas' or amphitheatres where the people were entertained with shows.
Second, the other measure that Asoka took to foster Dhamma was to encourage 'Dhamma Yatra', that is to say, encouraging visit to places associated with the life of Gautama Buddha.

Answer 2

Ashoka was inspired by the teachings of Buddha. He appointed officials, known as the Dhamma mahamatta who went to place to place teaching people about Dhamma. He also encouraged Dhamma Yatra that is to visit places that are related to Buddha. And even he took many steps individually to preach the people.
