It is possible to trap Vivec in Morrowind in Azura's star, and he has the ability to use CHIM.

Everyone says it is not possible to permanently kill a Daedra, they go back to a realm of Oblivion and reform. However, lesser Daedra can be captured and held indefinitely in soul gems. Perhaps if the Dwemer were still alive they could create a giant and powerful Soul Gem that could trap a full on Daedric prince? The Dwemer were also able to mantle and use the heart of Lorkhan - so why not?

The power of a soul gem does not seem to be very well understood, but they must be extremely powerful to be able to trap and hold Daedra or even potentially a Dragonborn forever.

So while it might not be possible to completely destroy a Daedric prince, perhaps someday one could be trapped and placed on a trophy case.
