Introduction to ASP.NET Microsoft Corporation

What We Will Cover Introduction to Microsoft ® .NET “ Classic” ASP Microsoft ® ASP.NET Server controls Data controls ASP.NET Web applications Business objects Web services Additional topics

Session Prerequisites This session assumes that you understand the fundamentals of Development on Microsoft ® Windows ® ASP or Microsoft ® Visual Basic ® This is a Level 100 Session

So Why This Presentation? ASP.NET offers many enhancements over classic ASP but… With ASP.NET, there’s a lot new to learn Solves many ASP issues RAD for the Web

Demonstrations ASP vs. ASP.NET Server controls walk-through Validation Data controls Cookieless sessions Web services Page caching

Agenda Introduction to .NET “Classic” ASP ASP.NET Server controls Data controls ASP.NET Web applications Business objects Web services Additional topics

Introduction to .NET 1 st Generation OS Services Microsoft provided COM, IIS, Internet Explorer Servers Data, Hosts Client Logic Biz Logic Applications largely operating in a client / server model were augmented with Web browser and servers. The industry focused on rich OS and local services provided by products like SQL Server™. Browsers Web app developers took advantage of these local services and used HTML to “project” the UI to many types of clients

Introduction to .NET 2 nd Generation Rich Client Logic Servers Data, Hosts Browsers Combination of “stateless” Web protocols with DNS and IP routing have enabled mass-scale “geo-scalability” “ Stateful” “ Stateless” & “ Geo-Scalable” OS Services Biz Tier Logic Separation of data and business logic provide greater scalability and performance while accessing enterprise and legacy data. COM+ Services improve reliability, scalability and manageability. Internet Explorer provides DHTML for better interactivity.

Introduction to .NET Web Services: The Next Generation Standard Browsers Open Internet Communications Protocols (HTTP, SMTP, XML, SOAP) Richer, More Productive User Experience Applications Leverage Globally-Available Federated Web Services Applications Become Programmable Web Services Smarter Clients Smarter Devices OS Services Biz Tier Logic Biz Logic & Web Service OS Services Public Web Services Building Block Services Internal Services XML XML XML Servers Data, Hosts XML Other Services XML XML XML HTML

Agenda Introduction to .NET ASP today ASP.NET Server controls Data controls ASP.NET Web applications Business objects Web services Additional topics

“Classic” ASP Successes Simple procedural programming model Access to COM Objects ADO File system object No compiling, just save Support for multiple scripting languages Mix HTML and code VBscript – leverage Visual Basic skills

“Classic” ASP Challenges Code readability Coding overhead PostBack complexity Reuse Performance DLL locking Deployment Sessions Caching

ASP.NET Architecture ASPX .ASPX

ASP.NET Architecture .ASPX Compiled .ASPX Compiled

ASP.NET Execution Model Visual Basic Source code Compiler C++ C# Compiler Compiler Assembly IL Code Assembly IL Code Assembly IL Code Operating System Services Common Language Runtime JIT Compiler Native Code Managed code Unmanaged Component

ASP.NET Features ASPX, ASP – side by side Simplified programming model Simplified deployment Better performance Caching Security Powerful controls

ASP.NET Features Simplified browser support Simplified form validation Code behind pages More powerful data access Web services Better session management

ASP.NET Features No DLL locking No DLL registration Simplified configuration Pagelets

Demonstration 1 ASP vs. ASP.NET Data-Driven ASP Data-Driven ASP.NET Comparison

Server Controls Simplify Common Tasks Simplify common tasks Forms Tables Data display Calendar Ad rotator Server-side programming model Automatic browser compatibility Less code, less complexity Extensible

Server Controls HTML and Server Controls <div id="MyDiv" runat="server"/> <asp:TextBox id="txtUserName" runat="Server"/> <asp:button type="submit" OnClick="SubmitBtn_Click" runat="server"/> ID – uniquely identifies control Runat – enables server-side processing OnClick – identifies server-side event handler

Server Controls Forms <script language="C#" runat=server> void SubmitBtn_Click(Object sender, EventArgs e) { Response.Write (“Hello” + txtUserName.Text); } </script> PostBack Server-side object automatically populated from client-side controls

Server Controls Browser Support Targets client on the fly <asp:textbox ForeColor=“red”/> Style Font Validation Client-side Server-side

Demonstration 2 Server Controls Walk-Through Programming Model Syntax

Server Controls Validation Without code Required field Within range Two fields equal (password) Regular expressions Validation error messages With code, but simplified Custom validation

Demonstration 3 Validation Required Field Validation Summary

Data Controls Bind to many data sources Collections Array HashTable ADO.NET DataReader DataSet XML

Data Controls ADO.NET Connection Command DataReader DataSet DataAdapter DataView

Data Controls ADO.NET Authors Connection Database DataAdapter DataSet Select … from Authors Authors

Data Controls ADO.NET Publishers Connection Database DataAdapter DataSet Select … from Publishers Authors Publishers

Data Controls ADO.NET DataSet Authors Publishers DataView DataGrid DataList Repeater

Data Controls DataGrid Displays data as a table Control over Alternate item Header Footer Colors, font, borders, etc. Paging Updateable Item as row

Data Controls Repeater List format No default output More control More complexity Item as row Not updateable

Data Controls DataList Directional rendering Good for columns Item as cell Alternate item Updateable

Demonstration 4 Data Controls ADO.NET DataGrid Repeater DataList

ASP.NET Web Applications Global ASAX Application_Start Application_End Session_Start Session_End Session Application

ASP.NET Web Applications web.config Site configuration file Like an .INI file for your site XML format Extensible Some settings Security Session Localization Tracing Debugging

ASP.NET Web Applications Session Variables Store state information No longer require cookies Share between servers <sessionState mode=“StateServer“ stateConnectionString="tcpip=127.0.0.1:42424" sqlConnectionString="data source=127.0.0.1;user id=sa;password=" cookieless="false" timeout="20" />

Demonstration 5 Cookieless Sessions Sessions with cookies web.config Sessions without cookies

Business Objects Problems with ASP and DLLs DLLs with .NET

Business Objects Problems with ASP and DLLs DLL Locking Page hit Shutdown Web application Shutdown Internet Information Server Edit in Visual Interdev MTS/COM+ Shutdown package Binary compatibility Registry

Additional Topics Deployment Scalability Caching Authentication and authorization Availability

Additional Topics Deployment Copy Components in .\bin No registering DLLs No locked DLLs Apps are isolated Each app can have its own version Uninstall Delete

Additional Topics Scalability Improvements ASP.NET pages are complied State shared across machines Managed providers Disconnected data access Caching

Additional Topics Caching Page output caching <%@ OutputCache Duration="60" VaryByParam="none" %> Page data caching Cache[“MyDataSet”] = SomeDataSet Like application variables Scavenging Expiration Dependencies

Additional Topics Authentication Supports basic, digest, cookie, and Windows authentication, Passport Form-based authentication Users or roles One API for user info

Demonstration 7 Page Caching Compare Performance

Call To Action Download the .NET Framework SDK Build a new ASP.NET application, or migrate from ASP

Session Summary ASP.NET offers many enhancements Improved session state Improved programming model Validators Caching In-place updating of sites The list goes on…
