On view page I have loaded content inside tabs. On user click inside tab I'm sending ajax request to the controller which sends back partial view. Everything works and now I want to implement caching on this tab content. So, I want to on first tab call content to be loaded and then cached for 60 sec. and the same for every other tab content.
I tried something like this
[DonutOutputCache(Duration = 60, VaryByParam = "activeTab")]
public ActionResult GetTabData(string activeTab)
{....}
but this display cached content of the first tab in every other tab.
Where is DonutOutputCache attribute defined? Maybe it isn't properly using VaryByParam?
In MVC 3 you no longer need to specify the VaryByParam option on the built-in OutputCache attribute.
[OutputCache(Duration=60)]
public ActionResult GetTabData(string activeTab)
{....}
Should be all you need.
I've never had success using caching Attributes on Actions in my ASP MVC projects. One of my co-workers says that he uses them and it works, but I've always had to either tell a page not to cache using this:
$.ajaxSetup({cache:false});
Or including cache: true / false in my $.ajax
$.ajax({ .... cache: false, ... });
Please refer below links.it's give proper details in output catching

I am building a .NET MVC 5 application on back-end and Angularjs on front-end.
I am loading .cshtml views in a div containerOne on a parent .cshtml page with ui.router and everything is working fine. An issue I would like to solve is when I enter manually a page URL that is C# controller's action path(in the example I provided below it is /Proposal/Customers) - my view is loaded on a whole page. What I want to be called is a .state named 'customers' in my example, or something like that. My example code is(part of my proposalConfig.js):
.state('customers', {
url: 'AllCustomers',
views: {
containerOne": {
templateUrl: '/Proposal/Customers'
}
}
});
On my back-end I have a ProposalController.cs and an action method Customers that calls a Customers.cshtml view.
Anyone has an idea how to solve this?
EDIT
The same thing happens if, instead of 'AllCustomers' I put '/Proposal/Customers', and then after the first load of a .state I refresh a page.
I forgot to mention that I have $locationProvider.hashPrefix('!').html5Mode(true); in a proposalConfig.js file.
If you mean that the entire page html markup (html tag, body tag and such)is being returned when you only want the specific content of the Customer.cshtml, which I also assume only has what you want in it, its probably because your view has a shared view start layout. Put this in Customer.cshtml
#{
Layout = null ;
}
So I have a scenario where I want to return my ActionResult...Return View("ViewName", "MasterPageName",model); in a popup window of a specific size I can pass...
E.G.:
public ActionResult PopUp()
{
//do some work...
//I want this returned in a popup window/modal dialog of some sort...
return View("ViewName","MasterPageName",model);
}
what is a reasonable way to accomplish this from the controller in asp.net mvc?
thanks in advance.
Nothing can be done on server side but you can decorate your action links like
<%= Html.ActionLink("Pop Up", "PopUp", null, new {target="_blank"}) %>
You can't manipulate the client side browser from a Controller on the server-side. What you can do is output script in your returned view, or call a controller that returns data via an AJAX call and pop-up from the client-side.
This is not something you can really do from your controller as this is code that executes on the server as the result of a http request and returns a response of some form or other. You will need to do this on the client, probably using javascript or alternatively you can call your controller action and specify the target attribute of the a tag as '_blank'.
Maybe you can try dynamically loading the rendered view using jQuery.load()
I've used jQuery dozens of times with PHP with great success. I'm working on an ASP.NET application and would like to use jQuery in the same manner.
Basically, I've got a masterpage that has the form and a webform that has all the form fields and data. A user can submit the form multiple ways - selection of a drop-down, button, etc. I want to catch all submits and use jQuery to submit the form. While the form is being processed, I want to display a new DIV with some text in it. Finally, I want to replace that div with the new form.
How can I accomplish this with the way that ASP.NET works?
Actually ASP.NET will post-back if you use its built-in JavaScript __doPostBack function. There's no other painless way for doing that.
That means you can use jQuery to handle drop-down lists, buttons or whatever (X)HTML element event and handler's body will invoke __doPostBack.
It's unclear that you want is a full-postback, but a partial one using AJAX.
If you're looking for a solution for sending form values to the server without a full-postback, I believe you've these options:
Callback API: http://msdn.microsoft.com/en-us/library/ms178208.aspx
Page methods, update panels: http://msdn.microsoft.com/en-us/magazine/cc163480.aspx
Anyway, let me give you an advise: ASP.NET works quite different compared to PHP and you'd not try to reproduce some known PHP solutions in ASP.NET. You need to change your mind.
About showing a DIV or anything while something is processed, play with initializeRequest ASP.NET AJAX PageRequestManager:
http://msdn.microsoft.com/en-us/library/bb397460.aspx
But that would depend on what AJAX API you're using, because since Microsoft AJAX will be replaced by jQuery in the next times, I'll need to say that you need to do that in some jQuery approach, like creating some $.ajax wrapper so your code will be able to listen when an asynchronous request is going to be made and you can perform actions by handling that situation like showing a DIV or any loading notice.
In ASP.NET Webforms formposts aren't as easy as they are in php. If you're new in ASP.NET development try http://www.asp.net/mvc. A common framework which allows you to implement TypedViews (ViewModes), simple request to modelbinding, and so on...
mh, sample:
[HttpPost]
public JsonResult Insert(string name, string vorname) // name&vorname filled by $_POST:)
{
var #new = new Person { Name = name, Vorname = vorname }
this.repo.Insert(#new);
return this.Json(new { success = true, newId = #new.Id });
}
So, I have a page that looks like the following:

This is my basic messaging inbox. I have 2 pages right now, Inbox and Sent (there will eventually be others). These both share the same View, and just have 2 different actions to populate the appropriate data.
The elements on the right-hand side (the message list) is a partial view which has its data populated based on my two controller actions Inbox(int? page) and Sent(int? Page).
So, I have one view "MessageView" and one partial view "MessageList" shared between Inbox/Sent.
However, I now have to get those arrow buttons ("<" ">") working using Ajax. I know how to use jQueries ajax calls well enough, and I know how to render the result of the action call (which returns a partial view).
The problem comes from the fact that the javascript that makes these pagination ajax calls needs to know two things:
What the current page is (whether it be /messages/inbox or /messages/sent)
What the current page is (specified in the query string, ie /messages/inbox?page=2).
Without knowing which page I'm on (Inbox or Sent), it wont know which url to make the ajax call on. Should it make the postback to /messages/inbox or to /messages/sent?
If I wasn't making these messages load with Ajax it would be as simple as loading the appropriate url into the link tags for the "<" and the ">" buttons. But I can't, because part of my requirements states that it must load the messages below without visibly refreshing to a new page.
In JavaScript you can check window.location.pathname to see the pathname section of the current’s page’s URL.
window.location.search gives you the query string.
When the user clicks the Inbox or Sent buttons, you need to rewrite the URLs in your arrows so that they point to the right place.
i have a problem when i RewritePath in HttpContext,
context.RewritePath(Utility.WebRoot + "List/Add.aspx", false);
It work fine to rewrite the url: http://localhost/List/Add
But when i hit the button it redirect me to http://localhost/List/Add.aspx
Is there a good way to "stop" the redirection to the .aspx page and just leave it on http://localhost/List/Add ?
Thanks for help
There is an issue with the From tag. You have to use a Control Adapter like this one:
http://weblogs.asp.net/scottgu/archive/2007/02/26/tip-trick-url-rewriting-with-asp-net.aspx
Go to the "Handling ASP.NET PostBacks with URL Rewriting" section.
This will help:

Basically the idea is to create a new Form control (I called my "ActionlessFormControl") that derives from the .Net Form control. The gist of it is that you override the rendering of the attributes and set your own value for the "action" attribute. What I do in mine is I remove the "action" attribute altogether which will post back to the same URL. Meaning, your page will post back to "/List/Add".
The benefit from using the inherited control is that you don't have to "register" each page. This will allow you to have dynamic content/URLS post back correctly.
