Viewing documents dependents on what plugins the user has installed and has little to do with C# or ASP.NET.   

Images and Videos use standard HTML tags.

The content-disposition header is the hint to the browser to download or display file.

How well this works depends on the browser, o/s, and plugins installed. Take PDFs for example. Safari always support displaying because it’s builtin to the o/s. Firefox uses a JavaScript routine to display PDFs. 

to display video, you need to render a page that has a media control which a src to the video.
