I want to access the public properties of the parent of the parent of the child component or in general of any ancestor component?

I found the solution for accessing properties of parent component but not for direct accessing any given ancestor in the hierarchy.

I noticed that some other framework provides direct access to the dom tree, can we have something like that into the angular for accessing component tree?

A global service is the solution, as described in the solution you posted. You can use it for any ancestor – Gianluca Paris Dec 19 '17 at 09:28
I agree as well. If you want to share data, use services. – pixelbits Dec 19 '17 at 09:29
Could this be the only solution? can't we search for any element in the hierarchy of the current component tree by the direct method? – Sandeep Sharma Dec 19 '17 at 09:32
Tried with @Host() but getting different copy of the parent component.. – Sandeep Sharma Dec 19 '17 at 09:34
What's wrong with services? – Gianluca Paris Dec 19 '17 at 09:35

you can directly inject any parent in the hierarchy – Max Koretskyi Dec 19 '17 at 10:18
ok.. I would try with this but using @Host() I were getting the different copy of the component. – Sandeep Sharma Dec 19 '17 at 11:12
Wow.. getting parent element with @ViewChild and injecting parent component into the child and accessing the element is working as expected. Thank you very much. – Sandeep Sharma Dec 19 '17 at 12:27
