MVC :: How To Call Post Action Controller From View Using Jquery
May 12, 2010
ia ma working on an asp.net mvc 2 app and i have a Users view, displaying all the users of the database. Then, i would like to add the ablility to display "users starting with fisrt name" capabaility on the same view. For this i created a list of all english leters that actually are links (<a href="#">A</a>, etc...)
I managed to handle the click event of each one of the letters and get the corresponding letter via jquery, but i don't know how to call theHttp.Post Users/FindUserByFirstLetterName(string letter) on the click event.
I cannot use the Html.ActionLink<> helper, since it redirects me to the HttpGet controller action.
I also tried using using jqery.Post but i also couldn't manage to call the action.

i have a website where i provicde a link. On clicking the link a controller action method is called to generate a zip file after creation of zip file is done, i show the link to download the zip file by replacing the link to create a zip with the link to download the zip.
the problem is that after zip file creation is over and link is shown, when user clicks on the link to download the zip file, they are sent to login. After providing correct credentials in the login page they are prompted to download the zip file. they sould not be sent to the login page. In the action to generate zip file i haven't abondoned the session or haven't not done anything that abondons the session.
the user should not be sen't to login page after successful creation of zip file user should be able to download the file without login. i search internet on this problem, but i did not find any solution. In one of the blog written by hanselman i found this statement that creates the problem with the session: Is some other thing like an Ajax call or IE's Content Advisor simultaneously hitting the default page or login page and causing a race condition that calls Session.Abandon? (It's happened before!)
so i thought there might be some problem with ajax call that causes the session to expire, but i don't know what is happening? it's like this after users click on the link to create zip file the zip file is created successfully but the session gets expired. this is not what i want. Why does the session has to get expired after making a jquery post call to controller action to create a zip file? i hope u understand the problem.

I got a list of checkboxes on my form, and a jquery script that catch a button click to get all the selected items (in an array) and post to a controller action.
This is my script: (yes A, looked at your sample but cannot get this to work)
[Code]....
That alert will print out correctly (like 1,3,5).
However when the above post hit my controller action, "selectedInvestments" are null, which I can't figure out why (back to my tekpub jquery videos, can't go on like this)
[Code]....

i would like to call an HttpGet GetEvents(Datetime dateSelected) controller action each time the user cliks on a date in jquery ui datepicker. I handle the onSelect datepicker event in order to call GetEvents() and refresh the Events page with the events for the selected date. The $.ajax method i use from jquery hits the GetEvents action, but instead of refreshing the page (and the url), i get an ajax result back.
[Code]....
So, how could i just call the HttpGet GetEvents() controller action via jquery, without the use of ajax in order to refresh the page?

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?

}
Basically I want to do this from my Action...
$.ajax({

In the view I have a HTML button:
<input type="submit" value="Submit" />
Also I have a dropdownlist, how do I call the controller's action after I click the "Submit" button?
And how do I pass the Model back to the controller action as well?
The reason I want to pass back the model (or other object/class) to controller's action is I might have 5 dropdown lists and 3 edit boxes values to be sent as parameters. So I would like to assign these parameters into a object and send it back to controller's action.

I have a simple controller that sends a model/data to a View:
[Code]....
The View displays the data in a HTML Table:
[Code]....
This View displays the data correctly and provides a RadioButton for each row. When I select one of the RadioButtons the previous selection is removed as expected.
For now I am using an ActionLink to enter another Controller action. I have tried many ways without success to retrieve the selected RadioButton's value in this controller action.
[Code]....
I have also tried defining the Controller action with a parameter matching the model without success.

Since a Controller Action and its View are associated with each other I would think that there would be a way to delete both in one step.

I'm a php programmer (code igniter) but interested in learning ASP.net MVC, I have a few question regarding this new exciting framework In php codeigniter's controller I can easily catch a post variable using
[Code]....
In comparison in ASP.net MVC we can create an action method that will accept post variable (but the parameter can get very crowded if we're passing a lot)
[Code]....
Or using FormCollection
[Code]....
Is there a way to catch post variable in ASP.net that looks like php's codeigniter? I mean not by adding the parameter, because I wanted a controller method that is flexible in receiving post request A controller that can accept and process any post request like in php (where we don't have to put that parameter to the controller method, we just call them

i just want to be able to call a javascritp subroutine on the client, after the server has done its thing (when an action completes or control goes to the view, i'd dont mind calling the js from the view either).
for some reason, even vs2010 doesn't let me put breakpoints in <% ... %> tagged areas between <script...> and </script> tagged areas. i for this reason can't figure out whats going on and how it's running things. here is what i've put in my view, and the javascritp should run, but it doesn't....
im just trying to call "RunOnceRoutines;" but it's not getting called!
the 2 questions: how on earth do we call javascript methods from server, and where is all this lovely javascript debugging i've heard about since vs2008? no where to be found!

But after logging-out then accessing previous open pages that needs authorization, they weren't redirected at all. This jQuery is initialize when a button is clicked,

}, function (data) {
if (data){
$('#div_user_active').html(data);
{ else {
$('#div_user_active').html('Not Active');

I'm gonna create profile page for my site. This page includes some 'Partial View' and each part posts some data.
My question is: How can I get posted data (strongly typed) from each partial view separately? Something like this:
[HttpPost]
public ActionResult Home(Model1 model1, Model2 model2, ...)
{
return View();
}
