What are the technologies of the web?

Web Development

At the time of ASP.NET 1…

JavaScript was a pain– But, IE6 held 96% browser share

.NET was brand new– WinForms was new, VB6 was popular

Yet to be invented:– AJAX*– jQuery– Web 2.0– Silverlight/XAML– Twitter

What is “ASP.NET”?

Core Services WebForms MVC Dynamic

Data AJAX

ASP.NET

HTML + JS asp.net webforms

On the Metal

Abstracted

asp.net mvc

introduction to asp.net 4.0

putting you in control

ViewState Control IDs Caching

Extensibility Control Rendering URLs

HTML + JS asp.net webforms

On the Metal

Abstracted

asp.net mvc

*important notes– Side-by-side enabled– Backwards & Upwards compatible

• controlRenderingCompatibilityVersion– VS 2010 only

ViewState can be opt-in

ViewStateModeEnabled/Disabled/Inherit

ViewState

4 Mode:– AutoID – Static– Inherit– Predictable (*default)

(+ ClientIDRowSuffix)

Control IDs

<!--Set client ID--><asp:ListView DataSourceID=“odsYourData" ClientIDRowSuffix="ID" ClientIDMode="Predictable"

<!--Global config-><system.web> <pages clientIDMode="Predictable"> </pages> </system.web>

Improved in 4.0

Routing

public class Global : System.Web.HttpApplication{ protected void Application_Start(object sender, EventArgs e) { RouteTable.Routes.Add("Product", new Route("Products/{category}", new PageRouteHandler("~/Products.aspx"))); }}

<asp:Literal Text="<%$ RouteValue:Category %>" runat="server" />

Global.asax

New APIs

Page.MetaDescription = "this is meta description";Page.MetaKeywords = "this is a meta keyword";

Page Meta Info

Response.RedirectPermanent(url); //issues HTTP 301

Permanent Redirect

HttpRequest.Browser.HttpBrowserCapabilities

Browser Capabilities (updated for new browsers + mobile)

Provider-based

Output Caching

<!--web.config--><caching> <outputCache defaultProvider="AspNetInternalProvider"> <providers> <add name="DiskCache" type="Test.OutputCacheEx.DiskOutputCacheProvider,

DiskCacheProvider"/> </providers> </outputCache> </caching>

<%--Configure cache provider per page/control--%><%@ OutputCache Duration="60" VaryByParam="None" providerName="DiskCache" %>

?

Newly extensible:– Object Caching

• System.Runtime.Caching

– Invalid Path Characters– Request Validation– Encoding

• <httpRuntime encoderType="Samples.MyCustomEncoder, Samples" />

– Browser Capabilities

Extensibility

New– QueryExtender

Improved– ListView– FormView– Paging– Outer tables– Hidden DIV CSS

Controls

Client-side libraries

Microsoft Ajax Libraries are dead*– Long live jQuery

What does it mean?For new client-side development, use jQuery

*NOTE: jQuery ships with ASP.NET 4

Dynamic Data

Core benefits:– Model-driven validation– Field Templates

Now more

flexible!

//Enable via CodeGridView1.EnableDynamicData(typeof(Product),

new { ProductName = "DefaultName" });

<!--OR Enable declaratively on page-%><asp:DynamicDataManager ID="DynamicDataManager1" runat="server" AutoLoadForeignKeys="true"> <DataControls> <asp:DataControlReference ControlID="GridView1" /> </DataControls> </asp:DynamicDataManager>

jQuery & MVC

Baked-in to ASP.NET

What’s Next

Razor & WebMatrix
