Mastering ASP.NET and ADO.NET with C#

Create a registration page in Visual Studio 2010, add text boxes for username, email, age, and password, and enforce required field validation to prevent incomplete submissions.

Master the range validator in ASP.NET to enforce age between 18 and 70, display custom invalid age errors, adjust validation message colors, and enable password masking for secure inputs.

Learn how to use the regular expression validator in ASP.NET to enforce a valid email format, configure the validation expression, display errors, and test with genuine versus fake emails.

Display all validation errors collectively with a validation summary control at bottom of page. Highlight invalid fields with an asterisk and color changes for a cleaner, clearer user experience.

Discover how to navigate from a registration page to default.aspx by handling the button click and using response.redirect, with validation ensuring entered values.

Explore page navigation techniques in ASP.NET with C#: navigate via hyperlink controls or explicit calls triggered by events, such as button clicks, using redirect and transfer-based navigation and cross-page postbacks.

Master this asp.net server.transfer technique to navigate within the same server without changing the address bar, preserving original form data and offering faster navigation than redirect.

Preserve form variables by using server transfer instead of response redirect, passing values from the form collection and displaying the text box input in a label on the destination page.

Explore server.execute and server.transfer navigation in ASP.NET, preserving original form variables via request.form, with server.execute dominating the current page while server.transfer processes the new page without leaving the first.

Explore how cookies in ASP.NET store small data on the client machine, differentiate persistent and non-persistent cookies, and configure expiry to control how long they live in the browser.

Demonstrates creating a username cookie on the registration page and storing the text box value. The default page reads the cookie on load and displays the username in a label.

Understand session state in ASP.NET, showing how data persists across pages for a single user, lasts for the session lifetime (default 20 minutes), and can be configured.

Understand how application state is stored on the web server and cleared when the process restarts, and how global data and sessions relate in ASP.NET and ADO.NET.

Explore managing application state in ASP.NET, protect labels from race conditions and deadlocks, and choose application state variables for global access or use a cache for limited durations.

Learn how application state tracks real-time connected users by globally counting them across sessions, updating on session start and end with application level events and a thread-safe lock.

Deploy apps to different IIS application pools to gain isolation, availability, and security; each pool runs its own worker process and identity (LocalService, LocalSystem, NetworkService, or application identity).

Navigate IIS manager to assign the default web site to an application pool, and create, configure, and manage application pools with alias names, pipeline mode, and managed framework version.

Explore authentication and authorization concepts and how anonymous authentication lets users access public site areas without credentials, and learn to enable or disable it in the ESB Dortmund interface.

Understand forms authentication for internet apps and its contrast to anonymous authentication. Users can access apps without domain membership, using ids and passwords, with classes in the system.web.security namespace.
