- 2. Session SummaryWebFormsLINQDynamic DataFutures – ASP.NET 4
- 3. What is ASP.NETTechnology for web application developmentProvides you with rich APIs and servicesRobust, scalable, fast development experienceGreat flexibility, less codingSeamless integration with Microsoft stack toolsNot an upgrade from ASPthe next generation ASP
- 4. WebFormsUI elements that make up the Look & Feel of your applicationAlso known as just Page.Code behind brings UI and code separationDefault.aspxDefault.aspx.csAdvanced features reduce codei.e. Data bindingRich Drag & Drop design experience
- 5. WebForms (contd.)Support for multiple languagesC#, VB, C++ and so onSimilar to Windows Forms programming modelEvents, Properties, MethodsExtensibilityThird party assemblies and controlsrunat=“server”Compiled at server-sideAccessible by server code
- 6. ASP.NET Controls or Web Controls
- 7. Most Commonly Used WebControls
- 9. Page Life Cycle EventsEvents in green are the most frequently used
- 10. Page Life Cycle Events (contd.)For more information: http://bit.ly/aspnetevents
- 11. WebForms Feature HighlightsThemes and skinsMaster pagesMembership, Profile and Role Manager APIApplication Services for AJAX applicationsWebsite administrationWide range choices for cachingLevels: Application, Session, Cache, Cookie, Page, Portion of PageHandling errors
- 12. WebForms Feature Highlights (contd.)ViewStateTechnique to persist changes to state of a WebForm across postbacksStores in a hidden input field __VIEWSTATEEncryptedIncrease length of the page, hence slows downYou can turn on/off
- 13. Cozying up with ASP.NET Developmentdemo Building a complete data driven site
- 15. Language INtegrated Query - LINQPronouced as “Link”A language constructStrongly typed query against objectsFull intellisense support Can be used with any collection of objects that implements IEnumerable<T>Highly extensibleLINQ to XMLLINQ to SQLLINQ to Flickr! etc.
- 16. LINQ BenefitsSimply put - avoiding having to learn and master many different domain languages, development or debugging environments in order to retrieve and manipulate data from different sourcesOne language to query all.Deferred ExecutionProcess queries only when foreach/ToList() is being called.Parallel Extensions help LINQ queries run in multiple processor cores in ASP.NET 4
- 18. Obtaining data sourceQuery Expression Syntax:varallProducts = from p in products select p;Extension Method:No representation. productsis the collection of objects
- 19. FilteringQuery Expression Syntax:varlowOnProducts = from p in products where p.UnitsInStock < 10 select p;Extension Method:products.Where(p => p.UnitsInStock < 10);
- 20. OrderingQuery Expression Syntax:varlowOnProducts = from p in products where p.UnitsInStock < 10 orderbyp.Name ascending select p;Extension Method:products.Where(p => p.UnitsInStock < 10) .OrderBy(p => p.Name);
- 21. Ordering (contd.)Other helpful Extension Methods:OrderByOrderByDescendingThenByThenByDescending
- 22. Groupingstring[] partNumbers = new string[] { "SCW10", "SCW1", "SCW2", "SCW11", "NUT10", "NUT1", "NUT2"};Query Expression Syntax: var query = from pN in partNumbers group pN by pN.Substring(0,3); Extension Method:var query = partNumbers .GroupBy(pN => pN.Substring(0,3));foreach (var group in q) {Console.WriteLine("Group key: {0}", group.Key);foreach (var part in group) {Console.WriteLine(" - {0}", part); }}varlowOnProducts = from p in products where p.UnitsInStock < 10 orderbyp.Name ascending select p;products.Where(p => p.UnitsInStock < 10) .OrderBy(p => p.Name);
- 23. Grouping (contd.)Iterating through grouped data:foreach (var group in query) {Console.WriteLine("Group key: {0}", group.Key);foreach (var part in group) {Console.WriteLine(" - {0}", part); }}
- 25. Standard Query Operators (contd.)
- 26. Querying and modifying datademo LINQ DataContext
- 27. LINQ Query ProviderRoll your own provider:YouTubeContextcontext = new YouTubeContext();var query = (from v in context.Videos where v.Location == " Moghbazar " && v.SearchText == “Rail Crash"select v).IfNotViewedBy(“TanzimSaqib”);Building LINQ Provider series: http://bit.ly/LINQSeries
- 28. Life easier withDynamic Data
- 29. Dynamic Data OverviewBuild powerful data driven sites in a minute!Automatic creation of WebFormsControls and data bindingValidation logic in placeMetadata inferred from schemaEasy and highly customizableTime saver and reusable
- 30. Building a website in less than a minute!demo
- 31. Field TemplatesFields are User ControlsDynamically chosen by datatypeResponsible forData bindingValidation andRenderingReusable
