I would like to exclude one of model's property from the Html.EditorFor. I tried [HiddenInput(DisplayValue=false)] but it renders the property as an hidden input. This could potentially be a security problem. How can we completely exclude a field from Html.EditorFor?

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.
Generally speaking we create a custom view for each page. So for an edit view of a car the model might be:
Car CarToEdit{ get; set;}
List<SelectListItem> CarManufacturers{ get; set;}
This has the advantage of giving a strongly typed view. It doesn't decouple the data layer well, but that is a separate issue. I'd then need to do something like (very approx syntax) :
<%= Html.DropDownList("ManufacturerId", Model.CarManufacturers)%>
Because of this, I can't use an EditorFor, and just pass in the model, as it would not render out the dropdownlists. So I think why not annotate the manufacturer field with UIHInt... great that works. ... but how do I pass in the data (both the manufacturerId, and the List<SelectListItem> to the hinted field?One solution is to have the UIHint control do a RenderAction. So the main view would include a line like:
[Code]....
Which would in turn go and render a view :
[Code]....
This works, but seems a little long winded. Can anyone suggest better ways of achieving this?Is anyone actually using UIHint?Also it would be good to be able to cache the output from the partial view (the dropdownlist) which is called from the RenderAction method... but output caches are is basically ignored on a render action (unless I've missed the point here).
Html.EditorFor(model=>model.Name)
Html.TextBoxFor(model=>model.Name)
tell the two diff,
do the previous one belong MVC 1.0 and the latter belong MVC 2.0 ? right?
I am generating the controls for an MVC Create Form using html.editorfor().How can i add style properties to whatever is created? For instance i have a control which is generated by html.editorfor() as a single line textbox but i want it to be a multiline textbox.

I'm finding my self with the problem that if I do not show the Template for a "complex" object I have in the main view object I still get the errors in the summary. How do i get around this?
I've got a model with say:
->Persons (has its own editor template)
->Pets(has its own editor template)
In the create view I show each one depending if they are not null. But when I try to validate HouseType and say I have Persons not null and pets is null. I get errors of validation for pets.
How do I get around this?
I've been trying to exclude an asp.net web control from the tabbing order.The control that i'm using is the RadioButtonList control. I've try setting the TabIndex to either 0 or -1.The problem that i'm running into is ... initially the control is skipped (which is good), but it seemed like the engine just shifted the control to the end of the tabbing order. Is this an expected behavior? or is there a work around for this?
After checking the HTML source, I have some interesting findings ...
<td><input id="rbSpiffType_0" type="radio" name="rbSpiffType" value="R" checked="checked" tabindex="-1" /><label for="rbSpiffType_0">Regular Spiff</label></td><td>
I think i might be tabbing into the label .
I am working on an ASP.NET MVC 2 project with VS 2010 and out of nothing I get the following errors on my views:
The name 'Html' does not exist in the current context
The name 'Model' does not exist in the current context
It is like it is not recongnizing the MVC Html and Model classes.
I have System.Web.Mvc on my references and on Web.Config I have:

I think I need to drop in some escape characters, but I'm not quite sure where. Here is the javascript function I'm attempting to call:
function setData(associateValue, reviewDateValue) {
var associate = document.getElementById("Associate");
var reviewDate = document.getElementById("ReviewDate");
associate.value = associateValue;
reviewDate.value = reviewDateValue;
}
Here is the asp .net mvc line where I'm attempting to create a Radio button with a click event that calls the above function and passes data from the model as javascript parameter values.
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('<%=item.Associate%>','<%=item.ReviewDate%>' )" } )%>
The above throws a bunch of compile issues and doesn't work. A call such as the following does call the javascript, but doesn't get the data from the model.
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('item.Associate','item.ReviewDate' )" } )%>
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('item.Associate','item.ReviewDate' )" } )%>
<% String functionCall = String.Format("setData('{0}','{1}')", Html.Encode(item.Associate), Html.Encode(item.ReviewDate )) ; %>
<%= Html.RadioButton("Selected", item.Selected, new { onClick=functionCall } )%>

What type of variable should I pass in the model to hold the choises?
So I have code as below
public ActionResult Create(AccountClassificationCreateViewModel ACCVM)
{
if (ACCVM.newMtn0130 == null)//Why ACCVM.newMtn0130 is null after [code]...
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.
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.
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)

I have a viewmodel with a property of a model class type. I set some properties in the model class to be able to show it to the user but then when I make a post, the model gets validated. How to overcome this? I don't want to enforce the DataAnnotations contraint in this case....

TheModel TheModel { get; set;}

I got 3 radion-buttons on the view called:
- Taxi
- Train
- Bus
The model passed has a property called "Transport" of type String. In the action, if I set the property as 'Train', then the view should set the radio-button 'Train' checked. ie.
Action:
model.Transport = "Train";
How do I do that in the view to make the radio-button Train checked?
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?

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.
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.

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.
but I am new with MVC and database-driven applications.
I hava a table with Cities (ID,Name) and one with Businesses(ID,CityID,Name). The later has a foreign key relationship with the first table.
I used a linq-to-SQL class to create my models.
My problem is that I need to access the City Name(not the ID) when displaying the Business Model View.
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.
