Data Binding with Relational Data

• Binding a GridView Control

• Sorting and Paging

• Enabling Data Modifications

• Displaying Master-Details Data

6
Retrieving XML Data
Retrieving XML Data with an XmlDataSource
Control

• DataFile The XML file containing the data
• SchemaFile An XML schema for the data
• TransformFile An XSLT stylesheet
• XPath An XPath expression to filter the data

Binding XML Data to a TreeView Control

• Create explicit node bindings
• Set TextField and ValueField properties

7
Demonstration RAD Data Binding in ASP.NET 2.0

• In this demonstration, you will see how to
• Use the SqlDataSource and GridView controls
• Use the XmlDataSource control

8
Master Pages

• Master pages
• Use the new _at_master directive
• Specify standard page layout and content for a
  set of content pages
• Contain named regions (content placeholders)
  where contentpages can display custom content
• Content pages
• Identify a single master page using the
  MasterPageFile attributeof the _at_page directive
• Implement content to fill content placeholders
  specified in master
• Provide programmatic access to the controls and
  public membersof their master page
• Nested master pages enable the creation of page
  hierarchies to modularize standard layout and
  content
• Visual Studio 2005 supports the creation and
  graphicalediting of master and content pages

Site Navigation

• Site Map
• Describes logical site structure
• Stored in any type of data store for which a site
  map provider exists
• Site Map Provider
• Follows Provider Pattern (must extend
  SiteMapProvider class)
• Provides link between Site Map and SiteMap object
  model
• XML provider uses Web.sitemap file
  (standard/default SiteMapDataProvider)
• SiteMap object model (SiteMap and SiteMapNode
  classes)
• Uses replaceable provider to access Site Map data
• Provides run-time access to navigation data for
  SiteMapPath and SiteMapDataSource controls, as
  well as custom controls and programs
• SiteMapDataSource control provides bridge between
  SiteMap and standard data-bindable controls
• Tree controls TreeView (new), Menu (new),
• Flat controls ListBox, BulletedListBox (new),

10
Themes

• Skin
• Collection of property values that define the
  visual appearanceof a specific type of control
  e.g. Button, Calendar, or GridView
• Defined using standard ASP.NET control syntax but
  with areduced property set
• Theme
• Named collection of skins, images, and style
  sheets
• Specified at the page level using _at_page directive
  to apply appropriate skins and styles to all
  controls on the page
• Specified at site or folder level using
  Web.config to affect allpages within scope
• Programmable at run time to offer enhanced
  customization and personalization capabilities

11
Membership and Role Management

• Membership system
• Solves common credential storage problem
• Replaces complex authentication code
• Functionality packaged in server controls
• User Management
• Validate credentials
• Create, Delete, Update
• Role Management
• Create, Delete, Update
• IsUserInRole / Roles for User
