C# - Get List<Model> Object In HTTP POST?
Dec 29, 2010
I have two model classes:
public class UserModel
{
public Guid Id { get; set; }
public string EmailAddress { get; set; }
public string LoginName { get; set; }
public string Password { get; set; }
}
public class GroupModel
{
public Guid Id { get; set; }
public string Name { get; set; }
public List<UserModel> Users { get; set; }
}
I created a View (Create.Aspx) by inheriting GroupModel class.
<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<MyApp.Models.GroupModel>" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Create</title>
</head>
<body>
<% using (Html.BeginForm()) {%>
<%: Html.ValidationSummary(true) %>
<fieldset>
<legend>Fields</legend>
<div class="editor-label">
<%: Html.LabelFor(model => model.Id) %>
</div>
<div class="editor-field">
<%: Html.TextBoxFor(model => model.Id) %>
<%: Html.ValidationMessageFor(model => model.Id) %>
</div>
<div class="editor-label">
<%: Html.LabelFor(model => model.Name) %>
</div>
<div class="editor-field">
<%: Html.TextBoxFor(model => model.Name) %>
<%: Html.ValidationMessageFor(model => model.Name) %>
</div>
<p>
<input type="submit" value="Create" />
</p>
</fieldset>
<% } %>
<div>
<%: Html.ActionLink("Back to List", "Index") %>
</div>
</body>
</html>
It is generating only two fields (Id, Name) in my aspx view. Also I am able to get the form data in the Model class object in Ñ‘[HttpPost]Ñ‘ request which contains the data for ID and NAME field in controller.
[HttpPost]
public ActionResult Create(GroupModel groupModel)
{
try
{
// TODO: Add insert logic here
return RedirectToAction("Index");
}
catch
{
return View();
}
}
How can I get the data in List<UserModel> object? I am thinking to Put a List control with checkboxes containing Users. Then catch them using FormCollection object in controller.

I am using ASP.Net MVC2 and LINQ to SQL. I am using DataAnnotations and model binding in conjunction with a Form/View and its working beautifully well. Loving that.. My view is an "Add new Employee" form that's adding a new "Employee" complex object. Every Employee also has a child complex object called an "Address".
I am using the bound Html helpers in the view, such as Html.TextBoxFor(model => model.NewEmployee.FirstName) for example. Working beautifully well, validating beautifully well both client and server and coming into the controller fully populated and ready to be saved! Exciting.. ModelState.IsValid returns true and I go to save the new Employee.
The Employee is created fine but the system also creates a blank/new Address record in my Addresses table even when the Address fields are blank! How can I prevent any Address from being created, in situations where I ONLY want to create a new Employee with no Address. An example is when the user supplies an existing Address, then I wish to simply set the new Employee's AddressID to that of an existing physical address (I hope that makes sense). But it could apply to any situation where you need to create a new complex object, but you don't wish for LINQ to create any of its child complex objects. I have tried setting NewEmployee.Address = null after it is received in the controller, but even after that, a blank/new Address is still created. Even if I try NewEmployee.Address = SomeExistingAddress, it does correctly link the Employee to the existing Address, but it STILL goes off and creates another redundant new/blank address record! Which is really weird..

I have a "Create New Employee" ASP.Net MVC form. My complex object is an Employee and an Employee has an Address, which is another Complex object. On my View/Form I collect all required values for both the Employee and the Address. I'm using the bound HTML helpers such as: Html.TextBoxFor(model => model.EmployeeAddress.StreetName)
AND
Html.TextBoxFor(model => model.NewEmployee.FirstName)
This is all working beautifully well. Model binding is working like a dream, both server side and client side validation using DataAnnotations is working beautifully well and I am nicely receiving my populated complex objects as expected in the Controller.. Now I'm trying to save.. The Employee should always be newly created, because its an "Add New Employee" form. But sometimes the Address is an existing Address and I don't want to insert another one. Rather, I just want to link the Employee to the existing AddressID of the one that already exists in the database.
So I wrote a nifty GetExistingOrCreateNewAddress(Address PostedAddress) method which works great so I end up with the correct Address to use and link to the about to be saved Employee object. This is all happening in the same DataContext, so no problems there..
BUT even when I link the about to be saved Employee object to an existing Address, on save a new/empty Address row is created in my Addresses table. Even though the newly created Employee does link correctly to the existing Address I told it to! Why is it so??? And how can I save the new Employee without LINQ automatically creating a blank Address for me. Because I'm explicitly specifying an existing Address it should be linked to instead!
[HttpPost]
public ActionResult CreateEmployee(EmployeeDetailsViewModel NewEmployeeDetails)
{
if (ModelState.IsValid)
{
EmployeeRepository ER = new EmployeeeRepository();
// Fetch or Create the appropriate Address object for what has been entered
Address ActualAddress = ER.GetExistingOrCreateNewAddress(NewEmployeeDetails.EnteredAddress);
// Link this Address to the "about to be saved" Employee
NewEmployeeDetails.Employee.Address = ActualAddress;
// Lock it in..
ER.SaveNewEmployee(NewEmployeeDetails.Employee);

I have developed a website that allows users to upload office documents then uses the office object model to convert the document to an HTML file that it then displays in an iFrame. I have, of course, included references to Office.interop.word, and the site works fine on my development machine. When I uploaded it to my production server the site functions fine until I try to upload a document. I initially got a similar error that said "COM object not registered". I realized that Word wasn't installed on my production server. So I installed word and now when the server tries to access the word object model I receive the following error:
Retrieving the COM class factory for component with CLSID {000209FF-0000-0000-C000-000000000046} failed due to the following error: 80070005 Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
I searched the registry for the corresponding CLSID and found a corresponding folder. I added full control to the IUSR_ account and due to the persistence of the error I eventually added full control to "everyone" and ensured these permissions inherited down to the rest of the folder. I then added full control to IUSR_ and again eventually added full control to "everyone" to my microsoft office folder. I don't know what other permissions to grant and where in order to make this "Access is denied" error go away. I must be granting them in the wrong place, because as far as I know I can't be any more permissive than "Everyone" "Full Control".

I have a requirement in my application that, while saving the application, need to get all the value from drop down list and pass it to the view model. But application should not allow the user to select more than one item from drop down list manually, ie, only one value at a time. My view model is like ...
public class ListManagement
{
public IEnumerable<selectListItem> InactiveProduct { get; set; }
public string[] InactiveProductSelected { get; set; }
public IEnumerable<selectListItem> ActiveProduct { get; set; }
}

I am working on a application which will accept the data in the post request.I will surely implement the data encryption to make sure that communication is secured. But my concern is, any body who knows the URL will be able to send the POST data request to my application, can I restrict the request from once specific IP address/URL.From a Request object can I find out which application/HOSTname/URL has sent this request. I looked at RefererURL but it can be populated and cannot be used. Is there any other field/properly which will tell me about the party who has sent this request.I want to make sure that I process request received from one specific URL/IP and want to ignore all others.

I want to do some processing on a attribute before returning the view. If I set the appModel.Markup returned in the HttpPost ActionResult method below to "modified" it still says "original" on the form. Why cant I modify my attribute in a HttpGet ActionResult method?
[HttpGet]
public ActionResult Index()
{
return View(new MyModel
{
Markup = "original"
});
}
[HttpPost]
public ActionResult Index(MyModel appModel)

return View(new MyModel
{
Markup = "modified"

Is there a way to force a non-secure form post to be secure? I understand there are ways to automatically resolve an http URL as an https URL but with form posts, is this type of redirection too late? Will the posted data have already gone through the wire as plain text?

i wonder something about mvc post method. for example I created a view "strongly typed" from a model (MyModel).
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Demo1.Models.MyModel>" %>
for Create actionsthere is two way.
first one takes MyModel as parameter
[HttpPost]
public ActionResult cart(MyModel md, int someID)
{
//some code
//.....
return View(MyModel);
}
second one does not take parameter as model.
[HttpPost]
public ActionResult cart(int someID)
{
//some code
//.....
return View(Mymodel);
}
for first one way, after form post the form values does not delete, I mean form does not cleared,after second one form is be cleared. why this diffirence?

I have a single model type to wrap up various models I want to use in my view:
public class QuestionViewData {
public Question Question { get; set; }
public IList<Answer> Answers { get; set; }
}
Now, in my question view I pull the data from the Question object - that's fine. Secondly I iterate through all Answer objects and pass them to a partial view:
<% foreach(Answer item in Model.Answers) { %>
<% Html.RenderPartial("ShowAnswer", item); %>
<% } %>
For each answer (in the partial view) I have some action buttons (like ratings). I'm using separate form POST's with hidden fields for every button. The problem is that I can't post the whole QuestionViewData model to my action method cause I only have the Answer object as model in the partial view. However, I need to return the complete question view from that action that takes QuestionViewData as model.

For now, I just want to use HTTP POST to send json to asp.net mvc2 controller.Since the JSON is actually a list of JSON objects, and each of them has different fields & length, so it hard for me to make up a input model.So I want to know is there a way for me to post JSON without model/ajax to a controller in ASP.NET MVC2?

I am using an Zencoder API to transcode video files. Once the job is completed they will do a HTTP POST with XML or JSON data containing the Job ID and other info to the url we provide.
So if URL is www.abc.com/GetZencoderResponse.aspx or .ashx, how can I read the data they post?
excuse me for the underlines, i thought that would make my query stand out.

We have some review coming up and my boss gave me a list of web page security vulnerabilities to look through and consider for our public site. I really don't understand the Get versus Post:
8Misusing HTTP POST and GET
Use POST to submit forms
Use GET to access resources
–NEVER use GET to authenticate users as it leaves a residual trace of all users in the web server access logs (not to mention web application proxy tools)
