MVC :: How To Supply A Antiforgerytoken When Posting JSON Data Using $.ajax
May 25, 2010
I am using the code as below of this post:First i will an fill array variable with the correct values for the controller action.Using the code below i think it should be very straigtforward by just adding the following line to the javascript:
data["__RequestVerificationToken"] = $('[name=__RequestVerificationToken]').val();
<%= Html.AntiForgeryToken() %> is at his right place and the action has a [ValidateAntiForgeryToken]
But my controller action keeps saying: "Invalid forgery token

I am lost, I am posing a jSon result to an MVC ActionResult and I cannot get it done. What I have is on the View:
[Code]....
With Firebug I can see that I am posting a jSon result with the result I selected. This result is comming from a select list(UnAssignedPages) as the items selected.
Now I want to iterate over that list in the controller and I cannot find an example of how to do it? I found a jSon value provider from Phil Haack [URL] but I was specifically told not to use the Futures Library. Is there any example of how to accept a jSon result in an ActionResult?

I originally have the question posted here, but I need as many eyes as possible on it.Essentially, I'm having issues redirecting to an action in mvc2 when working with JSON data. I post a stringified JSON object to an action and the action in turn redirects as needed. It worked previously when using form fields, but not when I'm posting JSON. To get posted JSON objects to properly bind to parameters objects in MVC, I'm taking advantage of the JsonValueProviderFactory class from MVC2Futures/MVC3Beta.Why is this occuring? The jQuery ajax call is telling the server "I'm giving you json, I expect html in return" and all actions pointed to via RedirectToAction calls are structured in a similar manner. I instead get stuck in a loop, continually hitting the originally requested action, with a prompt to reenter authorization information to boot! It seems lose authentication/authorization information in the process.The linked question on

I'm creating a page that makes multiple AJAX form posts without a page refresh.
I would like to use the ASP.NET MVC HTML.AntiForgeryToken() helper to secure the form against CSRF attacks. I think that each form on the page can share the same token, but will it allow multiple requests with the same token? If not is there a way to get a new token or some other way to secure the forms?

I have a form in formview which uploads data to my mssql databse fine. I want to send an e-mail after the data is uploaded to supply notification that someone has filled out the form. I am trying to use OnItemInserted to achieve this. This is the error message I get:
Compiler Error Message: CS0122: 'Personal_Loans.ClientappFormView_ItemInserted(object,
System.Web.UI.WebControls.FormViewInsertedEventArgs)' is inaccessible due to its protection level
linked to the line of code for the formview:
<asp:FormView ID="Clientapp" runat="server" DataKeyNames="Key" DataSourceID="ClientData" DefaultMode="Insert" OnItemInserted="ClientappFormView_ItemInserted" >
My code on the page behind is this:
void ClientappFormView_ItemInserted(Object sender, FormViewInsertedEventArgs e)
{
TextBox email = (TextBox)Clientapp.Row.FindControl("email");
DropDownList title = (DropDownList)Clientapp.Row.FindControl("title");
This is then followed by the e-mail sending code. The servers CAS level is set to "full" I have tried using capitals and all lowercase for OnItemInserted I get the same result.

I try to use the jquery + json to get all elements in form and build a JSON var to post in a ASP.NET MVC method.
[Code]....
It method get all fields in a form and build a JSON, but it dont put JSON inside JSON.
Example:
If i have the follow form:
<input name="person.name"><input name="person.age"><input name="person.address.street">
The serialized string build a JSON like this
{ "person.name": "??", "person.age": "??", "person.address.street": "??" }
I need a plugin or some function to generate like this:
{ "person": { "name" : "??", "age" : "??", "address":{ "street": "??" } } }

i am currently working on an asp.net mvc 2 web app and would like to add some ajax functionality on my delete item actions.Show, on the list items displayed view page, i wrapped the list items inside a partial view and added an ajax delete action link for each item (inside a foreach loop):
[Code]....
On the AjaxDeleteItem ajax controller action, i delete the selected item and redisplay the updated items list (via UpdateTargetId = "divList", where the list items partial view resides).My question is how i could insert Antiforgery token in such a scenario in order to secure delete operations from CSRF and XSRF attacks.

We have a web application that I've just enhanced (and gotten rid of the MsgBox in it , too!) It runs on our production web server. I have the solution loaded in VS2005 on my PC. It's been deployed before, but this is the first time I am deploying it and I want to make sure I know what I'm doing. So I will choose Publish from the Build menu, and I think I want to say Remote Site - is that what will plop all my new stuff over the old? And is the value that I supply for Remote Site the URL, or would I use the IP

1- I am using updatepanel and somethings work asynchronously and others do not which are in the same page.
But could it be that using the "same" trigger for two different update panels causes the first one to be asynchronously and the second one not?
2- In php u have something called $_POST['variablename'] which u get from a previous page. Is there anything similair in ASP.NET?
My point is that I have a dropdownlist and I want in the next page to launch a message depending on what the user chooses in the dropdownlist.
