RadioButtonList and Checkbox List
Key Notes
 Checkbox list and radiobutton list both
having “RepeatLayout “ properties
 ASP.NET 3.5 supports “Flow” and “Table”
layout

QUESTIONS & ANSWERS

Search Engine Optimization
Meta Description
Web Form Routing
Permanent Redirection

Meta Description
Key Notes
 Search Engine looks for Meta tag of our
web page to get the details of page
contents
 Two New Properties for Page Class
– MetaDescription
– MetaKeywords
 These can be defined from both code
behind and from aspx page
 Makes it easier to work with these than
defining with HtmlMeta.

Permanent Redirection
Key Notes
 Removes the problem of Temporary
redirection (302) using Response.Redirect
and ensures Search engine updates its
database about this redirection using
Response.RedirectParmanent(301).
 As the round trips will be minimized due
to ParmanentRedirection, Page rank can
be increased in Search Engines.

Web Form Routing
Key Notes
 ASP.NET MVC 2 introduces Routing features
in .NET Framework 3.5 SP1.
 Route Module is been added to
System.Web.dll so it is available readily to
any application.
 ASP.NET 4.0 already implemented of
IRouteHandler called PageRouteHandler, so
we do not need to implement the same.
 You need to register routes in global.asax or
any custom module. Once you register, the
routing will be available instantly.
 RouteData is available from any page to
access RouteTable.
 Response.RedirectToRoute allows to use
Route redirection from one page to another
by calling either routeName of routeValues.
 Support for Expression to generate RouteUrl

Smaller Web.config
Web.config Transformation
Performance Monitoring
Auto Start Application
Increase URL Length
Web Packaging & Publishing

Smaller Web.config
Key Notes
 Grown considerably over time as ASP.NET
adds up features from 2.0.
 In 4.0 major portion of Web.config is
moved to machine.config and all the
applications automatically inherits them.
 Which means smaller web.config just
shown in the figure.

Performance Monitoring
Key Notes
 Performance monitoring of a single
application running under one worker
process is difficult.
 ASP.NET 4.0 allows you to configure
ResourceMonitoring enabled from
aspnet.config (Not web.config).
 Managed Processor time and Managed
Memory used can be checked from
application performance option.

Auto Start Application
Key Notes
 Huge load of initialization weak up asp.net
application for first web call.
 IIS 7.5 introduces Application warm up
module to ensure your application always
keep running.
 You can use applicationhost.config to
configure your IIS worker process to keep
warm up module in action
 You can have managed hooks to the
system to write your custom code during
initialization using
IProcessHostPreloadClient interface which
will be called automatically before any
HTTP request is processed.

Web.config Transformation
Key Notes
 Separate Web.config files for Debug,
release, staging etc.
 Xdt:Transform and xdt:Locator lets you to
match certain portion of your config and
allow automatic transformation of
web.config.
 Locator can be specified using XPath,
Match, Condition allow you to find in
config easily.
 Transform includes Replace, Insert,
InsertBefore, InsertAfter, Remove,
RemoveAll etc.

Increases URL length
Key Notes
 Previous static length of url to 260 characters (based on
NTFS file path limit) can be configured from application.
 You can change the maximum size of URL using
HttpRuntime configuration.
 requestPathInvalidChars lets you to prevent characters
in URL.
 Support for URL in different browsers:
1. 2083 characters for IE with less than 2048 characters
in path portion of the url.
2. More than 100,000 characters are supported for
Firefox but address bar can only display upto 65,536
characters.
3. 80,000 for Safari.
4. 190,000 characters for Opera
Still it is not recommended to use more than 2000
characters in URL

WebPackaging & Publishing
Key Notes
 VS 2010 allows you to publish your application with a
single click.
 MSDeploy Publising, FTP, File System, FrontPage Server
Extensions.
 Packaging allows you to package your web application
into a compressed archive, which you later may use to
deploy the application.
 Allows you to deploy Files, Settings, Configuration, GAC,
etc.
 Sql Server deployment allows you to include SQL Scripts
with your package.

HTML Encoded Code Expression
Key Notes
 Till ASP.NET 3.5 we have used <

syntax for code expressions.
– <%: expression %>
– <%=
HttpUtility.HtmlEncode(expre
