How to create jQuery Datatable Drill-down rows?

In my MVC project, I am trying to use a single Datatable and collapse the rows for detail data as shown on Creating an expandable master-details table (jQuery DataTables and ASP.NET MVC integration – Part IV). On the other hand, I am looking for a similar examples of jQuery Datatable master-detail relations for ASP.NET MVC, but unfortunately I have not another suitable sample or tutorial from at least 50 pages on the web. Is there a similar examples like that? Thanks in advance…

ASP.NET jQuery Ajax Calling Code-Behind Method

I am very new to web development, but have a lot of experience in development in general. I have an ASP page that has a few input fields and a submit button.

First, the ajax call succeeds regardless of what data is provided to it. Secondly, the responseText field is the entire page’s html source.
