Session Objective(s) Understand the ASP.NET data strategy Understand the ASP.NET Dynamic Data feature

Key Takeaways Support for WebForms continues Support for MVC coming Model driven development across

multiple presentation layers

Session Objectives And Takeaways

An easy powerful way to build a data-driven websites Allows you to get started quickly using scaffolding UI can be completely customized

through templates and pages Validation and business rules specified

on data model flow through to UI Allows flexible URL routing, based on data schema and

separate from the physical page structure of the site New dynamic controls make scenarios like sorting, paging,

editing and filtering remarkably easy to implement Available now in .NET Framework 3.5 SP1!

What Is Dynamic Data?

Dynamic Data At A Glance

demo

Scaffolding

// Global.asax: Application_Startmodel.RegisterContext (typeof(NorthwindDataContext), new ContextConfiguration() { ScaffoldAllTables = true });

// WARNING: This enables scaffolding for every table in the model. To enable scaffolding on a per-table or per-column basis, you can use attributes on the model:

[MetadataType(typeof(ProductMeta))] public partial class ProductMeta[ScaffoldTable(true)] {public partial class Product [ScaffoldColumn(true)]{ public object UnitPrice { get; set; }

… }}

Routing

// Global.asax: Application_Start

RouteTable.Routes.routes.Add (new DynamicDataRoute("{table}/{action}.aspx") { Constraints = new RouteValueDictionary(new { action = "List|Details|Edit|Insert" }), Model = model});

RouteTable.Routes.routes.Add (new DynamicDataRoute("{table}/List.aspx") { Action = PageAction.List, ViewName = "List", Model = model});

RouteTable.Routes.Add(new DynamicDataRoute("MyCategoryDetail/{CategoryID}") { Model = model, Table = "Categories", Action = "Details" });

Scaffolding And Routing

Dynamic Data provides UI customization at many levels (from least to most control)

UI Customization

PageTemplates

FieldTemplates

UIHint/DataType on Model

CustomPages

UIHints on DynamicField/DynamicControl

Allow customization of columns using template based controls Based on the type of the column Source code for standard templates is provided Can be overriden with DataType and

UIHint attributes or properties Easy to create

Implement method to set and get values

Field Template Controls

DynamicDataManager GridView, DetailsView

DynamicDataField ListView, FormView

DynamicControl LinqDataSource, EntitiesDataSource

DynamicControlParameter DynamicQueryStringParameter

DynamicValidator DynamicFilter (UserControl), FilterRepeater

Dynamic Data Controls

UI Customization Demo

demo

Scenario: Reduce code in existing pages Validation

Move validation to data model instead of in individual pages. Change in one place affects entire site

Field Templates Add custom controls in one place

instead of in each of your pages Enable custom controls on model

Use In Existing Pages
