Generics

• Think of Generics as classes that are
  parameterized by type
• When you create a class based on Generics, you
  specify a type, and from that point on the class
  is locked into that type.
• Public Class GenericList(Of ItemType)
• Inherits CollectionBase
• Public Function Add(ByVal value As ItemType)
  _
• As Integer
• Return List.Add(value)
• End Function
• Public Sub Remove(ByVal value As ItemType)
• List.Remove(value)
• End Sub
• Public ReadOnly Property Item( _
• ByVal index As Integer) As ItemType
• Get
• ' The appropriate item is retrieved
  from

5
Generics

• Solve problem of loosely typed collections
• For Example, in .NET 1.x if you create a
  Collection or ArrayList, each element is of type
  Object
• Nothing prevents programmer of inserting
  incompatible types into collection
• Generic Collections available in .NET 2.0
• ListA basic collection
• DictionaryA name-value collection that indexes
  each item with a key.
• LinkedListA linked list, where each item points
  to the next item in the chain.
• QueueA first-in-first-out collection.
• StackA last-in-first-out collection.
• ReadOnlyCollectionA collection with a fixed set
  of items that can't be changed once it's created.
  
• SortedDictionaryA name-value collection that's
  kept in perpetually sorted order.

DEMO Generics

• Collection class in .NET 1.1 versus
• Generics in .NET 2.0

New ASP.NET Data Source Controls include...

• SQLDataSource Control
• Database agnostic component used to bind UI
  controls to data from a DB such as SQL Server,
  Oracle, OLE-DB or ODBC Data Sources.
• ObjectDataSource Control
• Used to bind UI controls to Middle-tier Business
  Logic Components (next presentation deals with
  this)

8
DEMO Using the SQLDataSource Control on a web
pagewith GridView

• Create a new Web Form
• Drag/Drop the Northwind Customers table onto the
  page
• A SQLDataSource control is automatically created
• A GridView control is automatically created
• Use the GridView SmartTag to allow sorting and
  paging, format

9
Support for Data Access Layer Components

• Use in N-Tier environments to separate
• User Interface
• Business Logic
• Data Access Layers
• TableAdapter is a new component that works with
  Typed DataSet
• Has Connection and Command objects to
  retrieve/update DB Entities
• Data Access Component generation frees developer
  from monotonous ADO.NET code

10
Demo Creating a Data Access Layer Component

• Add a new DAL Class Project
• Add a DataSet to the project called DSProducts
• Add a TableAdapter to the DataSet
• Enter the Query
• In Beta 2 you must uncheck Optimistic
  Concurrency/Refresh the DataSet
• Show the TableAdapter Configuration Wizard
• Show the TableAdapter Query Configuration Wizard
• Show how to add custom queries to TableAdapter

11
Demo Using a Data Access Layer Component from
ASP.NET

• Add a ProductList.aspx
• Add a GridView and ObjectDataSource to the page
• Set up the ObjectDataSource to use the
  TableAdapter
• Set up the GridView to use the ObjectDataSource
• AutoFormat GridView and select Paging/Updating/Del
  eting etc.

12
DetailsView and FormView Controls

• Used to display the "detail" of a record
• Common Scenario Master/Detail with GridView
  control as Master
• DetailsView is lightweight, does not support
  templates, suitable for no code scenarios
• FormView supports templates

13
DEMO Using the DetailsView control

• Add a Hyperlink column to the GridView, with a
  link to a ProductDetail.aspx?ProductId0
• Create a ProductDetail.aspx page with a
  DetailsView control
• Add an ObjectDataSource that uses the GetDataById
  method of our DAL component
• accept input from QueryString ProductId
• Autoformat and select Update/New/Delete options

14
Master Pages

• In .NET 1.x, User controls were used for
  consistent look and feel across pages
• Master Pages are similar, when a page is
  requested, it is merged with it's Master Page
  before being returned to the user

15
DEMO Master Pages

• Select Add New Item/Master Page
• Add some header and footer info
• Can optionally add default content
• Add a new Webform and check the "Select Master
  Page" checkbox
• open existing Webforms and add
• Page attribute MasterPageFile"/MasterPage.master
  "
• ASP ControlltaspContent runat"server"
  ContentPlaceHolderIDContentPlaceHolder1gt
• Test the Webform

16
Themes

• Maintain consistent appearance and layout across
  web app
• Skins
• collection of property values that determine the
  visual appearance of a specific type of control
• Examples background and foreground colors of a
  Button control or the font type and size used in
  a GridView control.
• Themes
• a named collection of skins, images, and CSS
  style sheets that can be applied to an entire Web
  application
• Any controls contained in pages to which the
  theme applies will have the appropriate skins and
  styles applied to them before they are rendered

17
Demo Themes

• Create a new folder in the \Themes folder of your
  application.
• The name of the folder you create is the name of
  the page theme. For example, if you create a
  folder \Themes\MyFirstTheme, the name of your
  page theme is MyFirstTheme.
• Add a base style sheet to the theme
• In Solution Explorer, right-click the Themes
  folder, click Add New Item, click StyleSheet, and
  then click OK.
• You can tailor the style sheet by using
  traditional CSS syntax.
• Create a Skin
• Create a new text file in your named theme folder
  with a .skin extension.
• The typical convention is to create one .skin
  file per control, such as Button.skin or
  Calendar.skin.
• In the .skin file, add a normal control
  definition (using declarative syntax), but
  include only the properties you want to set for
  the theme.
• Use the Theme
• Can be applied to individual pages using
  directivelt_at_ Page theme"ThemeName" ... gt
• Can be applied to entire site in web.config under
  ltsystem.webgt add ltpages theme"ThemeName" /gt

• now a SiteMap property will be exposed on each
  page.
• SiteMap.CurrentNode.ParentNode
• SiteMap.CurrentNode.Title
• Add SitMapPath and Menu Control to Master Page
• can use built-in navigation controls (Navigation
  section in toolbox)
• Menu control with flyout
• TreeView control
• Databind to SiteMap provider
• to add hierarchies, add a new SiteMapNode in XML
  hierarchy
• to add "Bread Crumbs" use the SiteMapPath control
