Opening and editing word document in a browser through asp.net

I have a requirement to develop an asp.net  web application that will open a word document in the browser and the user will be editing the document. On save of the document it should be pushed/uploaded to the server. 

Is there a way we can achieve this scenario using open xml?

It will be great if anyone can throw few lights on how to achieve this.

Thanks,

You can use open xml to create/edit the office documents on the server. But you cannot use it for rendering/viewing. You may need some other third party tool using which you can view the word document in aspx page.

Go through GoogleDocs API's and see can they help in manner.

You ca use "Tx Text Control" or "Aceoffix" for the job.
