I have a form which uploads a photo to my database, and I use a view model to aid in this process.
View Model:
public class GalleryViewModel
{
//Members:
public Gallery _photo { get; set; }
public string _title { get; set; }[code]...
When I debug the code, I see that the in the post method in my controller, all the information from the form is updated in the view model except for the uploadFile which is null.In the form I use enctype = "multipart/form-data". When I use my master page the uploadFile is null but when I use the default MVC master page everything works fine.
Here is my master page:
<%@ Master Language="C#" MasterPageFile="~/views/Shared/GeneralMaster.master" Inherits="System.Web.Mvc.ViewMasterPage" %> [code]....

I am working with a model which has the following, basically a Project can have a score between -5 and 5 and I'd like to show a dropdownlist of the available options, i.e 5,4,3,2,1,0,-1,-2,-3,-4,-5.
[Required(ErrorMessage = "Score is required")]
[Range(-5, 5, ErrorMessage = "Score must be between -5 and 5")]
[DisplayName("Score")]
public double Value
{
get { return value; }
set { this.value = value; }
}
What would be the best way to accomplish this using a dropdown list and how can I make the score of 0 the
default selection?

I'm using Model-View-Presenter framework. When Loading a page, I'm having trouble setting the selected item that came from the Database.
In view, I know I need:
protected void ddlStatus_SelectedIndexChanged(object sender, EventArgs e)
{
presenter.DdlStatusSelectedIndexChanged();
// what should this pass?
}
Then in Presenter:
public void DdlStatusSelectedIndexChanged()
{
view.DdlStatus = ???
// Should I pass the SelectedIndex?
}
I also think that part of my problem is that DdlStatus I have as a List.
Interface:
List<StatusDTO> DdlStatus { set; get; }
The best I found is here (but needs formatted!) ---> [URL]

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; }
}
[code]...

I have a problem:
I've created usual Controller and View(Edit view) for editing my Entity (EntityFramework)
Here is view example:
<div class="editor-field">
@Html.EditorFor(model => model.BirthDate)
@Html.ValidationMessageFor(model => model.BirthDate)
</div>
BirthDate is Nullable<DateTime>
but during loading my View I get this exception
The model item passed into the dictionary is null, but this dictionary requires a non-null model item of type 'System.DateTime'.
That's because of BirthDate is null in database but it is nullable and I expect that it just leaves the filed empty.
And I have Shared EditorTemplate:
@model System.Nullable<System.DateTime>
@if (Model.HasValue)

I am using System.directory services namespace in framework 2 to query active directory. I have used fixed user account impersonisation in the web.config file, find the code:
<identity impersonate="true" userName="enterprise ang09" password="Telcome123"/>
<authentication mode="Windows"/>
I have disabled anonymous access in IIS. Also i have given Read & write access to the account tang09 for the website virtual directory and Microsoft.NET folder located in windows folder. But still i get prompted for the domain username and password to access the website.

I'm building an MVC 2 RTM app, and I want to be able to share my model across applications. I'd *like* to be able to implement it like:ASP.NET MVC2 app (holds Views and Controllers)Class library to hold Model(s)WCF app to handle the data transactions with the models via different data stores across apps I had the MVC app working fine, but I wanted to abstract the data stuff and be able to work with the model across apps through the WCF site, so I created a class library project and moved all of the Models classes into that and set-up a WCF app, then added project references to the MVC and WCF apps that point at the class library. The idea was I can create services that take and return objects from the model via method calls across apps. It appears that everything's wired up correctly in the MVC project, so I'm passing the objects stored in the Models class library between controllers and views and everythig is compiling just fine, but for some reason the data is not being passed back from the views to the controller on POST -- all of the properties in the classes are null or empty.
When I debug the app, I can see that the values are stored in the model data dictionary but not the model object itself. What am I doing wrong? Am I on the wrong path, or missing something obvious (to some)?

Is it possible, inside a Custom Model Binder, to fire "something" that "says" the value is invalid so it gets handled by validation part?
Basically, I am getting an exception when the value for the property is invalid.

I made a few changes to the DB in SQL server management studio then right clicked on the .edmx doc to get it to update. That seemed to work fine but when i compiled the app everything that referenced the EF seems to be broken.The Error list now contains the below error for all classes that used it.
The type or namespace name '' could not be found (are you missing a using directive or an assembly reference?)

I have an issue of static variable in an asp.net application. Let's say I have a server with 8 CPUs running windows 2008 R2 hosting an asp.net webbsite, nothing fancy here, no funny configuration.
Is the following statement true? at any single time, there's one and only one process is running and accepting requests, even in the recycling stage. The reason I am asking is: I have a static field in my class, and I want to make that's the only static instance in the website. I've heard in some circumstances, IIS is recylcing your application, and it will start a new process, but the old process is still working, thus I will have 2 static instances in memory, which defeat the purpose of static field.
One step further, let's assume there might be 2 instances in memory, can I assume there are at most 2 instances at any single time? And can I assume once the second instance is up, the first instance will NEVER accept new requests?
Another question: Recently I have a problem with an applicationdomain concept. Looks like if an application domain causes a memory leak, unload the domain will not release the memory (Umanaged leak). So to what extent Application Domain is isolated?

I am trying to make a post that should use the Default Model Binder functionality in ASP.NET MVC 2 but unfortunately I can't get through. When I click on the checkout button I populate a form dinamically using jQuery code and then submit this form to the server. This is the form that get submitted
<form action="/x/Order/Checkout" id="cartForm" method="post">
<input name="__RequestVerificationToken" type="hidden" value="UDjN9RdWheKyWK5Q71MvXAbbDNel6buJd5Pamp/jx39InuyYIQVptcEubIA2W8DMUzWwnZjSGkLspkmDPbsIxy8EVuLvfCSZJJnl/NrooreouptwM/PaBEz2v6ZjO3I26IKRGZPqLxGGfITYqlf8Ow==">
<input id="CustomerID" name="CustomerID" type="hidden" value="1">
<input id="FirmID" name="FirmID" type="hidden" value="2">
<input type="hidden" name="CartItems[0].ServiceTypeID" value="1">
<input type="hidden" name="CartItems[0].Quantity" value="1">
<input type="hidden" name="CartItems[1].ServiceTypeID" value="2">
<input type="hidden" name="CartItems[1].Quantity" value="1">
</form>
This is the jQuery code that handle the submit event for the form
$("#cartForm").submit(function (event) {
event.preventDefault(); var form = $("#cartForm");
var panel = form.parent(); panel.parent().block();
$.ajax({ type: "post", dataType: "html",
url: '<%: Url.Content("~/Order/Checkout") %>',
async: false, data: form.serialize(),
success: function (response, status, xml) { panel.parent().unblock(); },
error: function (response) { panel.parent().unblock(); } }); });
This is the controller action that should be get called
[HttpPost]
[ValidateAntiForgeryToken]
public virtual ActionResult Checkout( CartModel cart ) {
} And finally this is the CartModel class involved
public class CartModel : BaseModel{
public int CustomerID { get; set; }
public int FirmID { get; set; }
public List<CartItemModel> CartItems { get; set; }
public CartModel() { CartItems = new List<CartItemModel>();
} } public class CartItemModel : BaseModel
{ public int ServiceTypeID { get; set; }
public int Quantity { get; set; } }
But the default Model Binder does not bind the web form data to a CartModel class. Using Fiddler I have been able to see that the data sent to the server is correct as you can see from the following snapshot.

when I use Html.HiddenFor( model => model.OwnerId ) to create a hidden field, the value assigned to that field is zero. When I use <input type="hidden" value="<%: Model.OwnerId %>" /> to add the hidden field to the form, the value is assigned correctly.
Why would Html.HiddenFor( model => model.OwnerId ) not get the correct value from the Model object? Am I supposed to load model state somehow separate from returning the model object from the action method? Here is the view:
[Code]....
The Create action method is relatively straight forward.
public ActionResult Create( ... )
{
ViewStockItem item = new ViewStockItem();
item.ActionCode = ActionCode.Add;
if (item.OwnerId == 0)
item.OwnerId = 7;
BookOwner owner = db.BookOwners.Single(c => c.OwnerId == item.OwnerId);
item.OwnerName = owner.OwnerName;
return View(item);
}

I've been used to decorating data model classes with data annotation attributes, but the purist in me baulks slightly at including purely presentational attributes such as display format here. I am, however, quite happy to keep validation centric attributes here. One good reason I have to continue keeping all annotations etc. in the data model is that my view model aggregates data model classes, e.g.
my ViewModelBase.DetailItem<TEntity> property in the view model is just a reference to an entity class in my data model. If I wanted to move presentational annotations to the view model, I would have to quite radically revise my design to one where I duplicate data model properties in my view model and use an object mapping tool to populate view model objects based on data model objects.

Say I got a domain model as follows: (and my repository expect an instance of this object)
[Code]....
And a view model (which my views are based on)
[Code]....
At the moment I got it like this and have my controller action manually create a new Person object from the PersonModel object before passing it on to the repository, which does not feel right.
So I tried to have PersonModel inherit from Person and pass that to the repository (also tried casting the PersonModel to a Person object first), but that don't work out.
What's the right way to have PersonModel automatically cast to Person? I want to keep this logic as my current structure allow me to keep things really loosely coupled, with the repository layer not having a clue how it's being used.

I have a WCF service in a virtual directory that is called in the code behind of a page that is in the parent directory, when i debug the code i can see the wcf service is being called, however when the service calls Membership.GetUser() it alway returns null. The user has already logged in to the asp.net site. When i call the service via jquery it does pick up the correct user, but i need to be able to call it via the code behind as well. I am developing in .Net 3.5 how i can make the Wcf pick up the logged in user?

I am using Directory entry of System.Directoryservices class of Asp.net for authenticating against Sunone LDAP server. The following works fine.
DirectoryEntry entry = new DirectoryEntry("LDAP://SunOne2:42028/dc=domain,dc=com");
entry.AuthenticationType = AuthenticationTypes.None;
entry.Username = "uid=thost,ou=people,dc=domain,dc=com";(replaced original values)
entry.Password = password;
entry.RefreshCache();
Now I want to be able to authenticate all the users of different organisation units. e.g. ou=development,ou=accounting etc., So I specified like this, entry.Username = "uid=thost,ou=people,ou=devlopment,ou=accounting, dc=domain,dc=com"; but it says "There is no such object on the server". I also tried putting ou in URL. I am not sure where should I specify this OUs to make my search broad. I found a lot on internet but no success so far.

I made a web form on a development website of mine (we'll call it dev.somewhere.com) and tried to publish it out to the web (we'll call it [URL]) in a subfolder. I named it default.aspx like I was supposed to and it worked flawlessly on the dev site. When I published it out the web, I wound up getting the following error when trying to get to the subfolder: [URL] Directory Listing Denied
This Virtual Directory does not allow contents to be listed. Confused and flustered, I tried to go to [URL], but I wound up with some error that won't tell me the problem. Instead it tells me to change the my web.config to read <customErrors mode="Off"/>.

As virutal directory points to physical path of the application, so if the IIS root directory is C:inetpubwwwroot and the application is stored at D:websites, than we need to create a virtual directory but if the application content is placed at C:inetpubwwwroot, then why still need to create virtual directory.
