A Guide to Website Marketing. Renaming a Razor file using Solution Explorer while the file is opened in the editor window causes syntax highlighting and IntelliSense to stop working for that file. This has been fixed so that highlighting and IntelliSense are maintained after a rename. This section describes changes new features and bug fixes made in the ASP. The project templates for ASP.

AdditionalValues dictionary for a model property. For example, suppose a view model has properties that should be displayed only to an administrator. That model can be annotated with the new attribute using AdminOnly as the key and true as the value, as in the following example:. This metadata is made available to any display or editor template when a product view model is rendered. It is up to you as application developer to interpret the metadata information. The T4 templates used for scaffolding views now generate calls to template helper methods such as EditorFor instead of helpers such as TextBoxFor.

This change improves support for metadata on the model in the form of data annotation attributes when the Add View dialog box generates a view. The Add View scaffolding also includes improved detection and usage of primary key information on the model, based on convention. For example, the Add View dialog box uses this information to ensure that the primary key value is not scaffolded as an editable form field. The default Edit and Create templates include references to the jQuery scripts needed for client validation.

The new Html. Raw method provides a simple way of displaying unencoded HTML when the content is known to be safe. The following example displays the same string, but the string is rendered as markup:. Previously, the ViewModel property of Controller corresponded to the View property of a view. Both of these properties provide a way to access values of the ViewDataDictionary object using dynamic property-accessor syntax.

Both properties have been renamed to be the same in order to avoid confusion and to be more consistent. The property was renamed to be more succinct.

The RemoteAttribute class's Fields property caused some confusion among users. Renaming this property to AdditionalFields clarifies its intent. The Html. ValidationMessage method was fixed to show the first useful error message instead of simply displaying the first error.

During model binding, the ModelState dictionary can be populated from multiple sources with error messages about the property, including from the model itself if it implements IValidatableObject , from validation attributes applied to the property, and from exceptions thrown while the property is being accessed.

When the Html. ValidationMessage method displays a validation message, it skips model-state entries that include an exception, because these are generally not intended for the end user. Instead, the method looks for the first validation message that is not associated with an exception and displays that message.

If no such message is found, it defaults to a generic error message that is associated with the first exception. In earlier releases, the model declaration at the top of a view added a blank line to the rendered HTML output. This has been fixed so that the declaration does not introduce whitespace. The first view engine always attempts to render the view.

By default, the Web Forms view engine is the first view engine; because the Web Forms engine cannot render a Razor view, an error occurs. View engines now have a FileExtensions property that is used to specify which file extensions they support. This property is checked when ASP. NET determines whether a view engine can render a file.

This is a breaking change and more details are included in the Breaking Changes section of this document. A bug was fixed where the LabelFor method rendered a for attribute that matches the input element's name attribute instead of its ID. According to the W3C, the for attribute should match the input element's ID. In earlier versions, explicit values that were passed to the RenderAction method were being ignored in favor of the current form values during model binding inside a child action.

The fix ensures that explicit values take precedence during model binding. This section describes features that have been introduced in the ASP. This tool automates the steps that developers take today to get a library into their source tree.

The list of project templates that is displayed in the dialog box is specified in the Windows registry. The new ControllerSessionStateAttribute gives you more control over session-state behavior for controllers by specifying a System. SessionStateBehavior enumeration value. The new CompareAttribute validation attribute lets you compare the values of two different properties of a model.

In the following example, the ComparePassword property must match the Password field in order to be valid. The new RemoteAttribute validation attribute takes advantage of the jQuery Validation plug-in's remote validator, which enables client-side validation to call a method on the server that performs the actual validation logic. In the following example, the UserName property has the RemoteAttribute applied. When editing this property in an Edit view, client validation will call an action named UserNameAvailable on the UsersController class in order to validate this field.

By default, the property name that the attribute is applied to is sent to the action method as a query-string parameter. New overloads have been added for the LabelFor and LabelForModel methods that let you specify the label text.

The following example shows how to use these overloads. The OutputCacheAttribute supports output caching of child actions that are called by using the Html.
