My requirement is to have a button in my view and clicking on that should generate a PDF report from that view. (Should avoid making another trip to database to get data for the PDF report).
I decided to use iTextSharp. Could some body please post some examples or direct me to a proper article?
I answered something similar on this link.
You will need to sort out the caching of the data from the DB though, this version just queried it again.

I would like to extract data from this web page using R:
I guess the web page is loaded via server using Ajax or something similar. Moreover I would like to save also the data available on the following pages, the ones that I can see when I press the NEXT button at the bottom of the data table.
Thanks a lot for any tips.

It appears to be generated using a JavaScript blob. You could look at rvest, which is an R library for just this problem (web scraping). If that doesn't work, RCUrl's GetURL function definitely grabs the script contents (although it's ugly as sin and you'll be wanting to grep it. Mind you, all automatically generated HTML is ugly).
Currently i have been using an iframe component to display a php page that i have written. the reason i used iframe rather than writing a joomla component in the first place was for 2 reasons, the information that is displayed in that page is from a remote mssql sever and the second was that i didnt really understand how to write one.
Now i have completed the creation of the php page that i display within the iframe, but now i need to be able to have it inherent within the joomla site, for both display reasons and security.
basically its a single page that displays information in a bunch of drop down boxes and then a submit button is clicked and it posts that information to another php page that again queries the mssql server and displays the results based on the post from the previous page.
query.php, posts some variables to results.php and is displayed in a table.
i have the functionality perfect, but i dont understand the documentation i have read so far. is there any simple component i can see the code of so that i can try and work out whats going on?
You might want to look at http://docs.joomla.org/J3.1:Developing_a_MVC_Component/Introduction and follow the process outlined.
How do I generate a multipage report in iReport where each page contains different invoice of a customer?
Also, each invoice will get its own datasource which is the detail as well as a support form of payment.
I've found how to implement a subreport here:
http://krams915.blogspot.com/2010/12/spring-3-mvc-jasper-sub-reports-using.html but I don't know how to create the multipage.
You can use page break after subreports. The contents after page break will be displayed in another page .
I have a requirement of having the same URL throughout the application navigations. Like below

This may make it very difficult for users to access your site - they won't be able to bookmark a specific page, for example.
It sounds like you want a single-page-app (e.g. like Google Mail or Reader). In this case, you have one page and make heavy use of AJAX. You can query the server via javascript, and send back Partial Views, or raw data in JSON format which can be rendered on the client, possibly via some kind of templating engine.
As Graham Clark has already mentioned, this functionality will most likely be frustrating for the user; however, achieving it depends on the complexity of your project. You may want to look into using jquery to load partial views into the main content area of your site.
When you click on your navigation you can use jquery's load() to replace the main content on the page. Jquery-load-with-mvc-2-partialviews is an interesting blog post that may give you more insight into what you would want to do. Your code to load content could look something like this:
$("#mainContent").load("/Controller/Action",
{parameter}, function () {
// perform javascript actions on load complete
});
I am building a webpage that needs to Query the database and display events in your area based on the users GeoLocation. I've seen this done so many times now on a lot of websites. But I have never built this functionality before.
I have the GeoLocation part functioning. When you land on the page it displays your zip code. I'm not sure how to grab that Zipcode from the div and query the database immediatley.? This webpage being is built using Orchard MVC/NHibernate.
Any suggestion would be helpful.
It sounds like you want the entire solution, but I'm not going to go into that kind of detail.
So I'll give you tips:
Use jQuery to grab the zip code from the DOM
Use jQuery to do an AJAX call to a action method in one of your controllers, passing the zip
Have the controller call the DB and hydrate the results into JSON
Have the controller return a JsonResult
Have jQuery handle the response of the AJAX call and do something meaningful
