MVC :: Can't Use An EditorFor, And Just Pass In The Model, As It Would Not Render Out The Dropdownlists?
May 9, 2010
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).

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?

Imagine I'm developing a webform with two dropdownlists and a submit button. The second dropdownlist depends on the choice in the first, and both are loaded dynamically using webmethods being called with javascript in de ASPX page (ajax). When I submit the form to the server, to save the data, I can't get the value of those dropdownlists. I think it is because with client AJAX no viewstate data is being generated. I need to send the data to the server and save the webform data, and identify wich data is on each webcontrol.

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)?

I have faced with some strange behavior and I hope you will be able to tell, what I do wrong. My goal is to change the order of some object. This object has property Priority which defines the order. Objects render as a list and user can drag elements for prepare order. When user click save, JS code modifies Priority property in hidden fields in accordance with order of elements in the list. And this form is sent to the server.

It's a multi-model view, and I'm achieving this through an IList<Book>. Each Book has a Title and an Author
So for example if I wanted to make 3 Books:
[code]....
However, I want to be able to generate such a form for any number of Books. I've done this before in Ruby on Rails through JavaScript and rendering partials, but I don't think I can render a partial in this case because the form changes (the index of the book has to increment for it to work)
EDIT: I'm looking for a way to do this in the Create view in particular. So in this case I don't have a list of books, but I'm building it.
A user should be able to click on a link that says "Add another item" and a form for another book should be appended to the bottom.

I'll give a very simple example:
at the moment I have to write like this:
<% Html.RenderPartial("hello", new HelloInput { Name = "Jimmy" } ); %>
I would like to be able to like this:
<%=Html.Hello("Jimmy") %>
So I would like to know how create this helper:
public static string Hello(this HtmlHelper helper, string name)
{
return the result of rendering partial view "hello" with HelloInput{ Name = name };
}

Let's assume we have a model:
public class Document
{
public string Name { get; set;}
public List<DayOfWeek> WeekDays {get; set;}
}
is it possible to render checkboxes that represents days of week for that model? i've searched the internet but did not find any solution. I mean it works whith CheckBoxFor(model=> model.SomeProperty) but it does not work if SomeProperty is List<DayOfWeek>. DayOfWeek here is enumerator.

I'm wondering how I can make one dropdownlist affect another one.. For example...You select your country from a drop down list of countries. On selecting it, another dropdown list becomes visible and displays the states of your country. I'm taking this data from a database, so it merely has to link to a different table for each country selected.
Also, I want the option of being able to add a 'state' to the database from the webform by typing whatever its called into the combobox so that future users will see that option.

I've been watching a video on Scott Hanselmnn teaching MVC 2 tricks/tips. He mentions how MVC 2 by default uses ASP.NET Web Forms view engine to render the output of the views; he mentions that the web forms view engine is a little slower than it could be for MVC 2 since it generates a control tree and then outputs the HTML to the page (I hope I said that right).
I was wondering what he meant by web forms generating a code tree before outputting the HTML to the page. Does anyone have insight on the view engine of Web forms and the steps of the rendering process works for ASP.NET and MVC2?

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 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 } )%>

I am learning MVC using the v2 release with Entity Framework v4. Let's say I have 3 objects Game, Points and Players. They are related in the following manner:Game has points and the Points can have a player associated with them ( 1 Game to many Points and a Point object can have one Player).
I am attempting to use the EditTemplates feature in MVC2 to render my views. In my Game Edit view I want to have the basic Game object information editable, and also the related Points objects. Currently I am utilizing "`<%= Html.EditorForModel() %>`"(Which seems pretty slow) to render the Edit View and then I have a specific Game and Point EditTemplates.
The data renders correctly and is editable for both the Game and Point information. When I go to perform the update and submit the form I receive the "Game" object in my Update ActionResult. The basic properties are populated for the Game object but any deep properties such as Points are not; they appear as null. If I look at the Request.Form variables in debug I can see the Points fields are being passed to the server but do not place themselves back into the Game object.
In my Game EditTemplate I am using the following to render the Points objects:
<%= Html.EditorFor(c => c.Points) %>
My Points EditTemplate looks like: [code]...
why this is rendering as "Points.Points[index] instead of Points[index]? I tried messing with the parameters in the EditFor:
<%= Html.EditorFor(c => c.Points,null,"Points") %>
but then the inputs render as Points.Points[index]

So I have two nested view models, CreditCard -> BillAddress. I have a view, "EditBilling", that has EditorFor(CreditCard). The CreditCard EditorTemplate has EditorFor(BillAddress), and the BillAddress EditorTemplate has EditorFor(BillState).
The end result is a select list with id "CreditCard_BillAddress_BillState".
I need to reference this in javascript, thus need to know the ID. In other situations, with non-nested ViewModels, I have used the following code:
$('#<%= ViewData.ModelMetadata.PropertyName %>_BillState')
The problem here is that the ModelMetadata.PropertyName property is only aware of the current property, not the parent(s). So I end up with the following:
$('#BillAddress_BillState')
How does one go about getting the client ID of nested strongly typed helpers?
