MVC 3 Razor DropDownListFor And Model Property From EFCodeFirst?

Feb 20, 2011

I am trying to populate a drop down list from my controller for a create action. I can display the dropdown as I want but when I cannot get the value to be stored in the database. My models:

[Code]....

Controller: [Code]....

View: [Code]....

This above snippet will show me the message "The value '50117dae-a7d7-4371-926f-7b1f7aaec133' is invalid."

if I change the line to @Html.DropDownListFor(ct => ct.CollectionType.CollectionTypeId, new SelectList(ViewBag.CollectionTypes as System.Collections.IEnumerable, "CollectionTypeId", "Title"))
@Html.ValidationMessageFor(model => model.CollectionType)

the page will not do anything - I believe this could be because the controller is trying to add a new CollectionType.

MVC :: Razor: Strongly Typed View With Model Containing Collection Properties?

Jan 4, 2011

Note: I'm working with MVC3 RC and Razor views.I've got this model:

[Code]....

I want to have a strongly typed create view for this model, that allows you to insert 1 to many addresses and phone numbers as part of the view. Ideally, the Action is strongly typed as well:

[Code]....

What would this view look like to facilitate creating 1 to many Addresses and PhoneNumbers, as well as having the state re-created correctly if the ModelState fails when posting? I've tried a number of variations including EditorTemplates and can't figure out how to do this.

MVC :: Getting The ID For A Model Property From HTML Helper

Jan 25, 2011

Is there a way to retrieve the client side ID for a model property similar to how the helpers like LabelFor etc generate the ID? For example, I have a model with a DateOfBirth property. I want to hook up that field to a jQuery DatePicker. Normally, I would hook up the date picker like this:

[Code]....

This works fine but hard codes the DateOfBirth property name. Ideally, I would like to use this:

[Code]....

Is this already available out of the box somewhere? I just created an extension method on the HtmlHelper class that does exactly this, but I wondered if there was already something built-in so I don't have to reinvent and test the wheel.

MVC :: View Model Property Become Null?

So I have code as below

I wonder why the ACCVM.newMtn0130 become null after RedirectToAction? I already assign with "_ACCVM.newMtn0130 = newMtn0130".

ACCVM._Error didn't become null after RedirectToAction.

MVC :: Bug - Get Value From Route Parameter Instead Of Property Of Model

May 18, 2010

I found little bug feature in MVC 2.

So, if we have in route defined parameter with same name as property at model and then we call it from strongly typed HTML helper (for example Html.TexBoxFor(x => x.PropertyName)), we get value from route parameter instead of property of model.

For example.

We have defined follow route:

[Code]....

Very simple model:

[Code]....

Next action in controller:

[Code]....

And very simple view:

[Code]....

Result you can see at follow picture:

I think what this dirty example described the essence of the problem. Let me know if I'm wrong.

MVC :: UpdateModel Calls A Property Get On The Model?

May 4, 2010

as the behaviour of the UpdateModel<T> changed in MVC 2 (RTM)? Since then I have the following problem when UpdateModel is called:UpdateModel<T1>(record, properties);record is typeof(Jumbo.Juist.Models.Bezorging) and properties is a string[] containing "Winkelnummer" and "OudRoutenummer".This now fails, because a get-property is being accessed: BerekendeAankomstTijd. In the past, it didn't fail. IMHO, this validation should be skipped, because it's only a getter (and thus/also not included in the string[] of properties to update)

MVC :: Set Radio Button Selection From Model's Property

Action:
model.Transport = "Train";

C# - MVC - Using Model Property As Form - Post To Action?

Jan 12, 2011

public class BandProfileModel
{
public BandModel Band { get; set; }
public IEnumerable<Relationship> Requests { get; set; }
}
and the following form:
<% using (Html.BeginForm()) { %>
<%: Html.EditorFor(m => m.Band) %>
<input type="submit" value="Save Band" />
<% } %>
which posts to the following action:
public ActionResult EditPost(BandProfileModel m, string band)
{
// stuff is done here, but m is null?
return View(m);
}

Basically, I only have one property on my model that is used in the form. The other property in BandProfleModel is just used in the UI for other data. I'm trying to update just the Band property, but for each post, the argument "m" is always null (specifically, the .Band property is null). It's posting just fine to the action, so it isn't a problem with my route. Just the data is null.

The ID and name attributes of the fields are BAND_whatever and Band.whatever (whatever being a property of Band), so it seems like it would work. What am I doing wrong? How can I use just one property as part of a form, post back, and have values populated via the model binder for my BandProfileModel property in the action?

Get DisplayName Attribute From MVC2 Model's Property?

Dec 28, 2010

So, I've got an contact form in my MVC 2 application.

I'd like to programatically email all properties of my "ContactModel".

Here is what I'd like to do in psuedo-ish code:

[Code]....

In case it matters...ContactModel sets up the DisplayName attributes like this:

[DisplayName("First Name")]
public string FirstName {get; set ;}

I'd like to keep this nice and DRY by not repeating the DisplayName names.

Specifically, I'd like to enumerate over each property in my ContactModel, get its DisplayName, and get its submitted value.

MVC :: HttpRequestValidationException After Using [SkipRequestValidation] Attribute On Model Property?

Nov 12, 2010

I think I might have stumbled onto a bug in ASP.NET MVC 3 RC. When I setup my MVC2 project in a new MVC3 project, copy paste classes, code, change name spaces, etc, etc, I ran into an issue in the following, simplified for explanation purpose, scenario:

Model:

public class WineDetails
{
[SkipRequestValidation]
[Required(ErrorMessage = "Beschrijving verplicht")]
public string Description { get; set; }
}

ViewModel:

public class ViewModelCreateWine
{
public MasterData MasterData { get; set; }
public WineDetails WineDetails { get; set; }
}

ActionMethod:

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult CreateWine(ViewModelCreateWine viewModelCreateWine)
{
GetMasterDataRegions(viewModelCreateWine);
if (Request.Params.ToString().IndexOf("Save") > 0)
{
if (TryValidateModel(viewModelCreateWine.WineDetails))
{
m_wineService.CreateWine(viewModelCreateWine.WineDetails);
return RedirectToAction("index", "Admin");
}
}
return View(viewModelCreateWine);
}

The ActionMethod "CreateWine" needs to call the "CreateWine" method in the WineService so that in the end a new Wine is added to the Database. So far it looks ok. As shown in the above code the [SkipRequestValidation] is set on the "Description" property of the WineDetails model so that the user can add Rich Text to the description and HTML elements are allowed during the Request validation. This works perfectly fine until the Params collection of the Request is accessed in the code to check if the Save button is clicked. When this line of code is trying to execute the following exception is thrown:

Exception Details: System.Web.HttpRequestValidationException: A potentially dangerous Request.Form value was detected from the client (ViewModelCreateWine.WineDetails.Description="<p>HTML Content with...").

The same exception is thrown when I put the [ValidateInput(false)] attribute on the action method. When I comment out the "if" statement and its content there is no issue and the model validation works just fine and skips the Request Validation on the Description property as expected.

In MVC2 the above code worked fine with the [ValidateInput(false)] attribute on the action method.As I said I'm not sure if this is a bug, it very well might be my own stupidity, but I thought it would be worth to mention here. So any feedback is more than welcome.

How can I do this? if from my controller I call the View passing the auto-generated Business Model, I only have access to the ID.

How To Return Errors To View From Controller Not Tied To A Specific Model Property

Aug 26, 2010

Curious what the best practice is for returning errors to a view from a controller where the error isn't really a validation error, but more like "user not found" or "service timeout" type of errors. (in ASP.NET MVC2 framework)

I've been adding them to the ModelState's model errors, but that doesn't seem appropriate. (although easy to implement and maintain)

Example - A user tries to log in, and their credentials do not match a known user.

MVC :: Model Not Validating Correctly In Controller. Optional Property With Required Children Fields

Oct 30, 2010

Basically I have RegisterModel2 that has a Person class. My requirement is that Phone Number and Address are not required for registration. But if they try to enter a Phone number of Address then it should validate it. Problem is that it is always stating that the child fields of Phone (area code, number) and child fields of Address (street1,city,etc) are required. Is there a way to annotate in the RegisterModel that a parent class is not Required but if any data in a child element is given then and only
then should the child elements be validated?

My Person EDM class has a nullable 0.1 -> 0.1 navigation property to Phone and Address.Here is the person class

[MetadataType(typeof(Person_Validation))]
public partial class Person
{
}

public class Person_Validation [code]....

The Person EntityObject has an optional/nullable Navigation Property to the Phone Object.


The Phone object has these annotations,[Code]....

I have RegisterModel defined as follows:
[Code]....

My View looks like this:

And here is my Controller Action it is posting to:
