ASP .NET
Platform
Page development
“Baked-in” application services
Run time
Introduction Active Server Pages .NET : Introduction Active Server Pages .NET Designer for Web Applications and XML Web services
Drag and drop for controls and HTML features
Rich language integration ASP .NET and Visual Studio® .NET are designed for Web Applications
Introduction ASP .NET : Introduction ASP .NET Builds on the programming classes of the .NET Framework
Controls and infrastructure simplify the building of Web Applications
Page Development Topics : Page Development Topics Separation of Code from Content
Dynamic Compilation
Server Controls
Validation
Custom Controls
Page Event Life Cycle
Page Development Separation of Code from Content : Page Development Separation of Code from Content Separation of Code from Content
Developers and designers can work independently Form1.asp Form1.aspx Form1.vb code code Separate files Single file ASP ASP .NET
Page Development Server Controls : Page Development Server Controls Server-programmable objects
Properties, method and events
Encapsulate behavior
Browser-neutral - Can render differently to support multiple browsers or other Web clients
You can create custom server controls
Page Development Page Event Life Cycle : Page Development Page Event Life Cycle Page_Load Page_Unload Textbox1_Changed Button1_Click Control events 1. Change Events 2. Action Events Page is loaded, control hierarchy initialized Page is disposed Control hierarchy is rendered
Page Development Demo : Page Development Demo Web Forms 101
Show simple Web Form with server controls
Demonstrate page life cycle
Page Development Input Validation : Page Development Input Validation Rich and declarative Validation
Validation controls declared separately for input controls
Extensible Validation Framework
Supports Validation on client and server
Avoids round trips for up-level clients
Page Development Input Validation Demo : Page Development Input Validation Demo Validation Controls
Demo of Validation Control
Page Development Server Controls Demo : Page Development Server Controls Demo Other Server Controls
Show online demos
Walk through a few medium level examples
Page Development Custom User Controls : Page Development Custom User Controls Simple way for page developers to author controls
Enables full encapsulation
Supports nested controls
Separate code namespace
Separate code language
Partition work across multiple developers
Reuse work across multiple pages and applications
Page Development User Controls Demo : Page Development User Controls Demo User Controls
Show creation and use of simple User Control
“Baked-in” Application Services Session State : “Baked-in” Application Services Session State Session state can be external from ASP .NET process
ASPState: NT Service
SQL Server™ 7.0/2000 temporary database
Big reliability wins
Session state survives crashes/restarts
Enables Web farm deployment
Session state can be shared across a Web farm of ASP .NET servers
Applications are no longer tied to one machine
“Baked-in” Application Services Session State Demo : “Baked-in” Application Services Session State Demo Session state
Show using session state in the application
InProc
Service
SQL
ASP .NET Runtime Improved Deployment : ASP .NET Runtime Improved Deployment Components can be dynamically updated
No more locked DLLs
Just copy a new DLL on top of an old one
No tools, no configuration changes, no application shutdown and no re-boots
Works great with Content Replication Systems
ASP .NET Runtime Improved Deployment : ASP .NET Runtime Improved Deployment
Sample Application Demo : Sample Application Demo Deployment via XCOPY
Deployment via MSI
Summary : Summary ASP .NET simplifies Web Application development
Scalable, better performing applications
Makes developers more productive
Makes systems more reliable
Makes systems easier to deploy
