MVC :: Internal Server Error On JsonResult Return?

Mar 5, 2010

I've got an ActionMethod that returns a JsonResult object and this isn't returning data to the calling jquery function. I have used wget to send and receive raw data to it, and I've discovered that when the object dataset is empty, it returns a value fine and the wget return is

HTTP request sent, awaiting response... 200 OK

Length: 78 [application/json]

Saving to: `filename'

but when there is data in the object dataset I get an internal server error:-

HTTP request sent, awaiting response... 500 Internal Server Error

2010-03-05 13:21:16 ERROR 500: Internal Server Error.

This is a dataset of objects being returned - are there any common "gotchas" when doing this?

WCF / ASMX :: Write Some XML Data After Web Method Return?

Jul 19, 2010

I am coding a classic .asmx web service. The method get data (as a string) from a server, then assign data to an object, then return that object. But I want to cache that object to a XML file for other request. It's because the data from server is not frequently change. Thus, after some minutes, I have to refresh the XML file. When I refresh XML file, I could write object to XML first, then return that object, but that approach maybe slowly.

How can I return the object for client first, then write this to XML file?

My controller has a member that returns a JsonResult object, it is coded as per below.

Is there a way to do this? I guess I am looking for the Json object to look something like this pseudo object:

ADO.NET :: Return String In LINQ Method?

I'm really new to ASP.Net and for a school project we have to create a login form. Now I have managed to create a login with LINQ doing the following:

And in my html page:

I was thinking something amongst those lines, but I can't call p.GebruikerWachtwoord. So I'm guessing this is completely wrong.I hope somebody can help me figure this out, and I apologise for the poor explanation, English isn't my native language.

Controller AJAX Method To Return ActionLink

Apr 4, 2011

I am fairly new to MVC and just trying to achieve something which I think shouldn't be too complicated to achieve. Just want to know what the best approach for that is. I have an Event-RSVP application (NerdDinner kind) where you go to view details of the event and then click on an AJAX link that will RSVP you for the event.

<%
if (Model.HasRSVP(Context.User.Identity.Name))
{
%>
<p>

You are registered for this event!

<%:
Ajax.ActionLink("Click here if you can't make it!", "CancelRegistration", "RSVP", new { id = Model.RSVPs.FirstOrDefault(r => r.AttendeeName.ToLower() == User.Identity.Name.ToLower()).RSVPID }, new AjaxOptions { UpdateTargetId = "QuickRegister"})

Return Multiple Types In Method's Signature?

Oct 13, 2010

I have two methods that do the similar thing. There are small differences here and there, which I can control by passing arguments to them when I call them, so I can effectively merge them. However one returns a string, and the other one an ArrayList. On the top of my head, I could merge them and return an Object, and then get the information I need. Is there a way though to return multiple types in the method's signature? What's the proper way to implement this?

C# - How To Return Json From Action Method With Array Property

Mar 14, 2011

I am trying to return some data as json from an action method.

I have an employee object that looks like this:

public class Employee
{
public int EmployeeID {get; set;}
public string FirstName {get; set;}
public string LastName {get; set;}
//Other irrelevant properties
}

Then I have a view model as follows

public Class EmployeeViewModel
{
public Employee Supervisor{get; set;}
public List<EmployeeViewModel> Employees
}

I need to return a json object that looks exactly like this:

{id: 1, name: John, children: [
{id: 1, name: Joe, children: []},
{id: 1, name: Rob, children: []}
]}

For now I only need to go to the second level as above, returning and supervisor and their staff members beneath them.

How would I go about returning this in my action method(I have the viewModel object hydrated already I just need to return it as json). My problem so far has been that the children property does not get populated.
