Content-PlaceHold

er

Page.Master• New property of System.Web.UI.Page• Provides content pages with programmatic

• Many data source controls provide built-in caching support– EnableCaching - Enables/disables caching– CacheDuration - Length of time (seconds)– CacheExpirationPolicy - Sliding or absolute– CacheKeyDependency/SqlCacheDepedency -

Cache dependencies• No-code data caching!

CacheSync• SQL cache dependencies

– Couple cached items to database entities– Change to underlying data evicts corresponding

item(s) from cache• Works with SQL Server 7, SQL Server 2000,

and SQL Server 2005– Requires database prep for SQL Server 7 and

SQL Server 2000 (Aspnet_regsql.exe)– "Just works" with SQL Server 2005

• Much-requested feature of ASP.NET

Membership and Roles

Profiles• Store per-user data persistently

– Strongly typed access (unlike session state)– On-demand lookup (unlike session state)– Long-lived (unlike session state)– Authenticated and anonymous users– Rich type support (including custom types)

• Accessed through dynamically compiled HttpProfileBase derivatives

• Provider-based for flexible data storage

Profile Definition<profile> <properties> <!-- String property --> <add name="MyName" /> <!-- Int32 property with default value --> <add name="MyFavoriteNumber" type="System.Int32" defaultValue="0" /> <!-- DateTime property --> <add name="MyBirthday" type="System.DateTime" /> <!-- Custom type; auth. and anon. users --> <add name="MyItems" type="ShoppingCart" serializeAs="binary" allowAnonymous="true" /> </properties></profile>

Data-Driven Site Navigation• Navigation UIs are tedious to implement

– Especially if they rely on client-side script• New controls simplify site navigation

– TreeView and Menu - Navigation UI– SiteMapDataSource - XML site maps– SiteMapPath - "Bread crumb" controls
