I'm implement Comet in Asp.net MVC, I used timer to keep Async request in server, Async request will complete when timer elapsed 1 minute and response to client (to avoid 404 error) and then reconnect to Async Controller. I also wanna execute some Synchronous action during Async request was holding, but the problem is: When an Async action was executed and hold by using timer, the Sync Action wasn't called until Async action (comet long-live request) completed. I did test with firefox 3.6 many times, but the result is the same, so strange, Do you know why ? I have a sub some questions : To implement comet, using timer (response after some minutes elapsed) or thread (response after several time sleeping thread) to hold async request, which is better?
I am implementing a CustomAuthorizeAttribute. I need to get the name of the action being executed. How can i get the name of current action name getting executed in the AuthorizeCore function which i am overriding?
I am desiging a master and details page from a search page..user can search for something and I need to display the result in jqgrid if the result has more than 1 row or record.. if the result is just one record then i have to directly send then to details page by skiping grid page... I do have an action method for results page and one more action method for Jqgrid data..i am trying to check the row count for the database result and trying to redirect to details action results..but its not working at all..and showing an empty jqgrid..
Lets say I have a simple controller for ASP.NET MVC I want to test. I want to test that a controller action (Foo, in this case) simply returns a link to another action (Bar, in this case).How would you test TestController.Foo? (either the first or second link)
My implementation has the same link twice. One passes the url throw ViewData[]. This seems more testable to me, as I can check the ViewData collection returned from Foo(). Even this way though, I don't know how to validate the url itself without making dependencies on routing.The controller:
public class TestController : Controller { public ActionResult Foo()[code].....
My httppost action doesnt seem to have received my model. The code is below;
[Code]....
i put a breakpoint on the line; return RedirectToAction("Error", "Dashboard"); and i found that appQualif carried no values whatsoever from the form i submitted..
I have one small problem. I am using Asp.Net web services in my application. In aspx application i have a condition that
for sample,
[code]....
look up my above condition. In the else if condition suppose a is greater than zero i wil call webservices. But what i need that suppose the services are not returned the value within 4 seconds, i will need to go to first condition that is call stored procedure. I hope you understand.
How can we achieve this condition. I thought that we can achieve syncronous. But i dont know exactly about it.
I've been using Html.Action("ActionName", "ControllerName") to invoke child actions across controllers without needing to have the view in ViewsShared. This has been working great for displaying things like session or cookie information.
Instead of just accessing cookies, I would like to pass additional parameters to Html.Action("ActionName", "ControllerName") so the action can execute different code based on the the data passed to the original view.
Should I be using a different method to pass parameters to a child action in a different controller?
I'm trying to add file upload functionality to a page. I've got a form that posts the selected file to a controller with a 'savefile' method. But if I don't add a get version of 'savefile' I'll get a 404 error. Here is the form code which is presented on the Index page:
[Code]....
And here is the controller code:
[Code]....
Intuitively I don't think I should need a GET version of SaveFile but if omit it I get a 404 error when the form posts. Why should I need a GET version of SaveFile when all I want is to post a form and save the file?
I have a controller with a bunch of actions as such:
[Code]....
I'm looking for a way to find out which action invoked the other: for instance, when redirecting to Action1, I need to know whether it is coming from clicking "next" button at Action0 or clicking "back" button at Action2. This is is to avoid performing Action1 twice (My app is like a wizard, if I click back button at Action2, I don't want to execute Action1 again).
I'm a newbie into MVC and I am like only on chapter 7 in ASP.NET MVC Unleashed so be easy with m
[Code]....
how do I tell Create Button to send to an Action named Create and to Edit to an Action named Edit on the same form?I guess it is possible on ASP.NET MVC if it is possible on ASP.NET Webforms
I have a page with three partial views. On the first ascx, I want some data posted when a user clicks on "submit" button, and send that data to another POST action "search" and search the db with that data, the final output should be the view returned by "search". How do I do this?
Now imagine that you're writing an ASP.NET app and you've generated a proxy for the service with the async operations. You create an instance of the service, wire service.GetCustomerCompleted to your handler, OnGetCustomerCompleted, and call service.GetCustomerAsync("12345"). In OnGetCustomerCompleted you apply logic to detect that no customer was found and throw a custom exception, or you want to throw the exception found in e.Error, e.g.:
void OnGetCustomerCompleted(object sender, GetCustomerCompletedEventArgs e) { if (e.Error != null) throw new ApplicationException("GetCustomer failed", e.Error); if (String.IsNullOrEmpty(e.Result.FirstName) && String.IsNullOrEmpty(e.Result.LastName)) throw new CustomerNotFoundException(); }
(I've omitted the bits of code that sets up a Customer object and persists it through the calls.) You launch the call to GetCustomerAsync in Page_Load and expect to retrieve the result in a handler wired to Page.OnPreRenderComplete. My question is, how do you catch the exception in your page? I know you can catch it with Global.asax's ApplicationError, but what if you don't want to navigate away from your page?
i have the code for asynchronous call to the database. i execute the sql command into the begin method that will executed onto the separate thread. now i want to execute the another database call asynchronously so that this also execute onto the separate thread. code for one database cal is here....
I'm looking for some opinions on how to go about the following:
Say I have a wizard control in my website, and I've completed all the steps on the wizard and I want to redirect to another page after the "Finish" button I've clicked. So, then after that I logout of my site, and go back into it bearing in mind the wizard has been completed, I want to redirect the user to another page and by-pass this wizard control. Would I setup a flag in the database, to indicate if the wizard control has been completely filled or not. If status = true then redirect the user to different page (and bypass wizard)... but if status = null then make sure user still can go through steps in the wizard control.
[Code]....
set a flag to state whether all of the wizard has been filled in or not / otherwise go back and complete the wizard?
I think everything clear here. But I don't like that parameter int k which I never use and which I pasted in order to create another function which will be launched when some data was posted to that action.
I have a problem, whereby if I browse to a page using a url of the form: site/home.mvc/Index where Index is an action on the Home controller, my page displays as I would expect.
However, if I browse to site/home.mvc the page loads, all except for my images which are replaced by red crosses.
i'm creating a mvc application and i'll use under subdomain like http://myapp.mycompany.com
This subdomain is pointing to app subdirectory, but my actions are always generated with applicationPath (subdirectory) like:
http://myapp.mycompany.com/myapp/Home/About // I want just this without additional paths http://myapp.mycompany.com/Home/About Is there any configuration related to this? Is this the correct way to generate links? <%= Html.ActionLink("About", "About", "Home") %>
I have 2 views for a input operation in my application.
The first view (lets call it view1) submits a form. Based on the form some operations on database is done and second view(View2) is returned with some other data from the database as a model.
controller action code :
[AcceptVerbs(HttpVerbs.Post)] public ActionResult View1(FormCollection fc) { //database ops to fill vm properties View2ViewModel vm=new View2ViewModel(); return View("View2", vm); }
Now, since I return a new view and not a action redirect the url is still http://url/View1 but everything works as it is supposed to.
The problem:
When I submit the form in View2 it calls the View1 action method, not the View2 action method. Probably because the url is still View1. What can I do to call the action View2
