Spring and ASP.NET Web Development

Windows Forms 2.0 introduced DataGridView (replacing the old DataGrid), WebBrowser (for embedding web content), and MaskedTextBox (for formatted input like phone numbers). The DataGrid control existed in 1.x and was replaced by DataGridView, not introduced in 2.0.

DataGridView control allows interaction at the individual cell level - you can click to select, edit, and format specific cells. While you can select entire rows or columns, the primary focus for interaction and presentation is the cell level.

ASP.NET 2.0 introduced SqlDataSource, XmlDataSource, and ObjectDataSource controls to simplify data binding. These were new declarative data source controls that eliminated much of the code required in previous versions. ODBC data sources existed prior to 2.0.

Strongly typed datasets encapsulate both table definitions and column data types within their schema, providing compile-time type safety. Unlike untyped datasets, they know the structure and data types at design time.

ASP.NET 2.0 introduced DetailsView and FormView as new data-bound controls for displaying data. DetailsView displays one record at a time in a table layout, while FormView provides more customizable templated rendering. ListView was introduced in ASP.NET 3.5.

Master Pages in ASP.NET 2.0 provide a template for creating consistent layout across multiple pages, defining shared elements like headers, footers, and navigation. They're not specific pages like home or menu pages, but rather layout templates that content pages can reference.

Themes in ASP.NET are composite units that include skins (control property definitions), CSS files, and images. All three components work together to provide a complete visual styling system that goes beyond what CSS alone can offer.

Themes can define many properties beyond style properties (like images, templates) and can include stylesheet references. Option B is incorrect because themes CAN include auxiliary files like graphics - this is actually one of their advantages over pure CSS. Option D is unrelated - it describes membership management.

Membership and Role Management provides comprehensive user account management (create, modify, delete users) and role administration (create, delete roles). Option C is incorrect because caching user information is handled by separate caching features, not the membership system. Option D is unrelated content about themes.

Membership controls in ASP.NET 2.0 include Login (authenticate users), ChangePassword (modify password), and PasswordRecovery (reset forgotten passwords). RemoveUser is not a control - it's a method available through the Membership API, but there's no visual control named RemoveUser.

The Profile service in ASP.NET provides persistent per-user data storage that persists across multiple sessions, unlike session state which is temporary. It allows storing user-specific preferences and data that survives session expiration. Options C and D are unrelated.

ASP.NET 2.0 introduced TreeView and Menu as new navigation controls for structured site navigation. TreeView displays hierarchical data, while Menu provides dropdown/flyout navigation. Hyperlink existed in earlier versions, and Tools is not a navigation control.

Web.config contains standard configuration sections including appSettings (application settings), connectionStrings (database connections), and compilation (build settings). System.Data is not a valid top-level configuration section - database providers are registered differently.

System.Web and System.Net are top-level configuration section groups in Web.config. System.Web contains ASP.NET-specific settings like authentication, authorization, and custom errors, while System.Net contains networking configuration like mail settings and request authentication. Pages and authentication are individual sections within System.Web, not separate section groups.

ASP.NET 2.0 introduced built-in providers for Membership (user management), Role (role-based security), and SiteMap (site navigation). These providers offer a consistent API for common tasks without requiring developers to build from scratch. Webservice is not a provider - it's a communication technology.

Bin (compiled assemblies), App_Code (shared class files), and App_Data (database files, XML files) are special ASP.NET folders with specific runtime behaviors. Debug is not a special ASP.NET folder - it's typically used in development but doesn't have reserved status in ASP.NET.

SiteMap datasource integrates seamlessly with both Menu and TreeView controls to provide hierarchical navigation. This is a common pattern in ASP.NET for building consistent navigation across a site. The SiteMapDataSource control reads from web.sitemap and binds to these data controls.

The Core Container Module is the foundation of the Spring Framework, providing essential functionality like IoC (Inversion of Control) and dependency injection. BeanFactory, the heart of this module, manages bean configuration and lifecycle. Other modules like AOP, DAO, and ApplicationContext build on this core foundation.

The ApplicationContext module extends BeanFactory and adds enterprise features: internationalization (I18N), event publication, resource loading, and validation. This is what makes Spring a complete framework rather than just an IoC container.

The AOP (Aspect-Oriented Programming) module enables aspect development for cross-cutting concerns like logging, transactions, security. It implements proxy-based AOP using JDK dynamic proxies or CGLIB.
