OS Services Microsoft provided COM, IIS, Internet Explorer Introduction to.NET 1 st Generation 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 Servers Data, Hosts Client Logic Biz Logic

Combination of “stateless” Web protocols with DNS and IP routing have enabled mass-scale “geo-scalability” “Stateful” “Stateless” & “Geo-Scalable” Rich Client Logic Introduction to.NET 2 nd Generation Servers Data, Hosts OS Services Biz Tier Logic Browsers 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.

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

Server Controls HTML and Server Controls ID – uniquely identifies control ID – uniquely identifies control Runat – enables server-side processing Runat – enables server-side processing OnClick – identifies server-side event handler OnClick – identifies server-side event handler

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

Server Controls Browser Support Targets client on the fly Targets client on the fly  Style  Font Validation Validation  Client-side  Server-side
