Hin: अशोकनगर ashokanagar
‘Ashok Town’ [Pachhar] Town/District, Madhya Pradesh (MP)
From (Emperor) Ashoka; and Hin: nagar, ‘city’, ‘town’.
The suggestion that the name derives from an overnight visit from the famous Mauryan Emperor en route to capture Ujjain is popular and there is nothing else to go on.
