Display external website page in asp .net mvc 5 - asp.net-mvc

I am building a website for a class project using ASP NET MVC 5, wherein I need a section of the website to display a page from a different website. The goal is to somehow embed that page in my view, so UI interactions are still possible with the embedded page, as if the page was visited directly in the browser (the end effect is that the page is rendered and allows interaction but my website theme always stays around it)
I know one way to do it is to just put it inside an iframe in my View. But I want to know if there is a different solution. My instructor suggested using partial views, but I can't figure out how to achieve the same result. Can anyone suggest a different way to achieve this ? Also, what would be the right way to do this in terms of security (I believe iframe is), but I want to know other's opinion ?
Thanks.

I suggest you use a sandboxed IFrame e.g.
http://www.html5rocks.com/en/tutorials/security/sandboxed-iframes/
<iframe sandbox="allow-same-origin allow-scripts allow-popups allow-forms"
src="https://blah.com/index.html"
style="border: 0; width:130px; height:20px;">
</iframe>
You can tweak how much power the content in the Iframe has (i.e. can it run scripts).
I guess you could also look at using a partial view. My guess is you'd need to use a WebClient instance to download the HTML source of the target webpage, and then pass that HTML into a partial view. But I don't see how any script tags would render correctly for you, which means the page would not be interactive.

jquery mobile multi-page internal hyperlinking

This appears to be pretty basic but I can't figure it out.
Using a jqm multipage template, I'm trying to allow users to jump from a link one page (id='page1') directly to an image in another page (id='page2').
FIDDLE
It appears I am constrained, by html hyperlinking rules and jqm, to this:
<a href='#page2'>go to image on p2</a>
... which of course jumps the user to the top of page2.
But that's not what I want. I want the user to jump directly to the IMAGE, which is close to the bottom of page2, tagged like so:
<img id='image-id'>
But tagging the link with the image's id (not the page's id), i.e. tagging it like this
<a href='#image-id'>go to image on p2</a>
doesn't work.
I get the feeling I'm missing something very obvious, but can't figure it out.
Any suggestions? Or is this not possible?
I've got a different problem but found this question in my travels... thought I would add an extract from the jquery mobile page:
http://demos.jquerymobile.com/1.4.5/navigation-linking-pages/
Note: You cannot link to a multipage document with Ajax navigation active because the framework will only load the first page it finds, not the full set of internal pages. In these cases, you must link without Ajax (see next section) for a full page refresh to prevent potential hash collisions. There is currently a subpage plugin that makes it possible to load in multi-page documents.

How to update iframe page tab content using a form?

I am trying to pass data using a form to a Facebook iFrame page tab but can't seem to figure how to do it.
I have a page tab on my Facebook page with several elements such as links and images directing users to various pages on the main website. This is updated every week, so rather than update the HTML file and upload via FTP everyweek i would like to see if i can create a form to pass the new data to the iframe.
In addition the Facebook page tab cannot be created in PHP as the server is running ASP.NET
I am trying to do this without the use of a database table if possible, using POST or GET would be preferable.
If anyone knows of any tutorials or has any tips i would be very grateful.
Cheers
You can only pass content or interact with iframe content if it's on the same domain as the parent webpage that has the iframe. All browsers have a "same origin policy" that prevent you from being able to do that - sorry :(

How is this URL modification possible?

Could anyone please tell how the site http://www.outsharked.com/imagemapster/default.aspx?what.html is working in such way? Modifying the url without loading/reloading the page. I think this is not done by html5. Because it works in IE6 which doesn't support html5.
I created that site. The commenter is correct, it uses Javascript to change the URL. There's nothing about how that navigation works that is different for IE6 - that browser supports the necessary client-side functionality to do this kind of thing. The basic functionality involves:
capturing click events on the nav, and loading the inner content via AJAX
update the URL to reflect a working direct URL to target.
The links also are valid anchor links that, in the absence of Javascript, would go to the same page (but load the whole thing). This is your basic AJAX web site setup with one minor difference. It's common practice to use a URLs like this in AJAX/single page web sites:
http://mysite.com/home#somepage
or even just
http://mysite.com/#somepage
Where the hashtag part represents the actual page a user has navigated to. If someone accessed that url directly, e.g. from outside the site, the site would use Javascript to load the correct content based on the hashtag, after the page had loaded. This means that there might be a little delay for the inner content to reflect the correct page, since it has to run another request after the initial page has loaded from the browser to get the inner content via AJAX.
I was trying to avoid that by creating a setup that worked completely with and without Javascript. If you go directly to a URL within the site such as http://www.outsharked.com/imagemapster/default.aspx?faq.html you will notice it loads the content directly. This URL will work even if Javascript is disabled. You can't actually do this using hashtags, since hashtag content is not sent to the server. Only the client knows what's after the hashtag in a URL. That's why I was using query strings to represent inner pages.
This site architecture was sort of an experiment at the time. It works pretty well but the code isn't fantastic, I didn't really do anything else with it, and I'm sure there are other better-fleshed-out/tested/full-featured frameworks out there to do much the same thing.
But it might not be a bad example of the nuts and bolts of creating a basic AJAX navigation setup, as a learning tool, since it's pretty concise, and also does HTML5 history navigation (e.g. so the back button works on modern browsers).

Umbraco - different behaviour for usual and ajax requests

I'm developing an Umbraco site that is a "single page" - no reload, only ajax calls.
The site will have nice urls and use html5 push state history.
The problem here is that every time a request is made to the server I need to handle it differently depending on the type of the request: normal or ajax.
For usual requests I need to display the content along with it's master page.
For ajax requests I need to display only the content.
I don't know how to accomplish this - routing and master page magic.
Can anyone help?
You could use alternate templates. For more information see here. Basically, have the alternate template just render out the content in whatever format you want, without the full html template, and then make sure that all your AJAX requests call the pages using the alternate template.
One word of warning though, if you're doing all the site navigation with AJAX and no page reloads, then Google (or most other search engine spiders for that matter) won't be able to index your site properly (as they don't process javascript) and your site won't rank very well.

Silverlight Application - Embedded advertising possible with HTML or Silverlight?

I have a 100% silverlight application that takes up the entire screen.
Plan A: I would like to embed other silverlight ads but I cannot find any companies that provide this service.
Plan B: Embed classic HTML ads into the app. I've found one way by playing around the with DIV's and Javascript but it seems like a major hack. do not want.
Anyone managed to display ads with silverlight?
the possible solution may be "you can use web service which feed ad-data to SL application, and then display it."
All silverlight application are embeded in html using object, for example:
<object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%">
It means you still can have other html element in the page where you have silverlight. You even can create new html elements and add that to the page in your code behind.
So one solution is to create a div element in the page that is hosting silverlight and show it in front of silverlight object using z-index. And there are atleast two ways to implement this solution:
In code behind. Way to access html element in code behind file:
HtmlElement mydiv = HtmlPage.Document.GetElementByID("mydiv");
Using javascript
It is a workaround, but we have to stick with it until silverlight can embed html inside it.
