I love MVC, coming from WebForms development, but there are things that don't make any sense to me. The "Error executing child handler" occurs anytime a vast number of things happen, for instance. It's very close to a useless message. In order to get the actual cause, I click on Debug/Exceptions and check the "Common Language Runtime Exceptions", and then reload the View. Presto! It shows the cause of the error.
Another thing I'm wondering about today is the FormCollection value of the Html.CheckBoxFor control. Checkboxes in general seem badly designed in html, and MVC didn't improve on it much. When processing a POST, if a regular checkbox isn't checked, it simply won't show up in the list of posted elements. Great. Instead of just grabbing it by name in the FormCollection and testing its value, instead I have to test whether or not it exists in the FormCollection. Not very intuitive. The Html.CheckBoxFor is a variant on the same theme. It always shows up in the FormCollection, but with a similarly non-intuitive return. If it's not checked, it yields a value of 'false', which can simply be converted to boolean and processed as normal. But if it is checked, it returns 'true,false'. Super. Now, instead of converting its value to a boolean directly, I have to test the string returned for the index of 'true' and return that instead.
I find this close to as aggravating as the Linq To Sql Sum() method bug. If I run a Select() method on a given numeric property and run Sum() to add them all together, if an empty result set is returned by the query it throws an exception. Now, if I was looking at a bunch of totals to add together, and none of them had anything entered, what would I write in the sum box? Error? Exception? Nope, it would be zero. I fully understand that if no results were returned then nulls cannot be added, but according to the intitial documentation this method was supposed to return zero in such an instance regardless, because that's just common sense. Enough of that rant. Does anyone know why this return value was chosen for Html.CheckBoxFor?

I have this C# code in a Razor view:
@(Html.CheckBoxFor<RazorSamplesWeb.Models.SamplesModel>(i => i.IsActive))
I tried translating it to this:
@Code Html.CheckBoxFor(Of RazorSamplesWeb.Models.SamplesModel)(Function(i) i.IsActive)End Code
But it's complaining. Why, and what is the right statement?

I need to build a custom html helper that generates Label and a tooltip Icon(based on the Display(Name = 'MyProperty', Description = 'ToMyToolTip') attribute). This is how my helper looks like so far:
[Code]....
The problem is that the label have a attribute called "for", I need to set this also but do not find the value in the metadata object? Do I have to manually create the value to the "for" attribute? And if so, how is the best way to do that?

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 } )%>

We're working on a new ASP.Net site. The last major site we did was in classic ASP--the procedure we used there was to have the HTML completed first, then "bring it to life" with the ASP code.
In the ASP.Net world, how does this work? I.e. how do the designers do their work if much of the mark-up is actually being generated by the server controls?
We are also looking at ASP.Net MVC as a potential lightweight alternative.
Would be very interested to know what was worked best for people in both scenarios in terms of working with the designers and integrating their work with the code.
UPDATE: I refined what I was asking here, not exactly the same question but similar enough so this one could probably be merged with it.

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.

I have a web page with a form in the footer, when the user clicks submit in this form I submit their data and then return the view with the model with the line
[Code]....
but this means that the user is at the top of the page and cannot immediately see the validation errors or success message on that page as this information is posted in the footer section so is there a way to return a view with the model and a html fragment so the url is http://website/page#footer so that they can see this straight away without having to scroll down.
Also I have to assume the user has javascript turned off and the user could be using browsers ie6 and greater.

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?

I have a RegisterModel view model I use for my new account registration page. Depending on the status of a registration task, the model has a relevant text message to display for the user, e.g. "Waiting for email confirmation" etc.
I currently populate this string property in the manner below, but couldn't help wondering about mixing markup and content like I do with the <p> tags. Is there a better or more accepted way of doing this, besides having multiple partial views with actual HTML literals instead of model properties?
RegisterMessage = "<p>Please use the form below to create a new account.</p>";
RegisterMessage = string.Format("<p>Passwords are required to be a minimum of {0} characters in length.</p>", _membershipService.MinRequiredPasswordLength);
EDIT: I have just noticed that the <p> tags are rendering literally, but I doubt that issue falls under the same question.

i am working an asp.net mvc 2 web app using model metadata and some of the model metadata don't seem to work when using the default Html.EditorForModel().For example, when applying the DefaultValue(1) and the ReadOnly(true) attributes on a model field, the field displayed on edit view has zero for its default value and it is not read only.

I don't know if this is even possible, but here goes: I have an ASP.NET page that contains an IFrame that calls an HTML page. Is it possible to pass a variable from the ASP.NET page to the HTML within the IFrame? More specifically, I'd like for the ASP.NET page to fill in one of the fields on the form within the HTML page.

Currently, I am working with ASP.NET MVC1 and am still learning about Model Binding and how values from a View are passed back to the Controller / Model. Specifically, I want take an existing Model, create a Table and populate the Rows of the Table, allow the user to edit some fields and pass it back. In my example, I have a Class called "Ingredient" which has 4 public accessories: Name, Barcode, Amount, and Unit.
[Code]....
Or is this not possible? (Basically, I'm trying to re-create a datagrid where certain fields are editable and certain are not...)

I have implemented a custom ModelMetadataProvider so that I can decorate my view models with some custom attributes and everything was working fine until I made use of a Partial View. The following code in my view works fine: -
<%: Html.DisplayFor(x => x.Results) %>
Results is a List which renders a custom display template and is also decorated with a custom attribute. Using breakpoints, after the above line and prior to the code within the custom display template, the overridden CreateMetadata method in my custom ModelMetadataProvider is invoked. If I look at the attributes collection parameter I can see that it does contain my custom attribute thus everything working as expected. However, if I replace the above with the following line of code in my view then it breaks: -
<% Html.RenderPartial("ApplicationSearchResults", Model.Results, new ViewDataDictionary()); %>
All the Partial View contains is: -
<%: Html.DisplayFor(x => x) %>
Again using breakpoints, after the above line and prior to the code within the custom display template, the overridden CreateMetadata method in my custom ModelMetadataProvider is invoked. But this time if I look at the attributes collection parameter my custom attribute is not there.
