Microsoft Expression Web 3

What is Microsoft Expression Web

Microsoft Expression Web is WYSIWYG editor and general web design program. Expression Web makes creating compliant standards-based Web sites faster and easier. With a state-of-the-art design surface that generates clean CSS, you can make design decisions on the fly, knowing that you're seeing a faithful representation of the final browser-rendered page.
Drag and drop controls simplify adding rich media, such as Silverlight from Expression Blend™, Flash, and Windows Media. And advanced Photoshop file import gives you complete control over imported layers.
And if you like to work in the code, Expression Web has you covered there too. With support for a broad range of essential Web technologies, such as PHP, JavaScript, XML/XSLT, and ASP.NET you can use the same tool for both visual design and coding.

What's new from Microsoft Expression Web?

One of the comments from somasegar’s blog asked if there was a plan going forward to unify them into a consistent UI framework/experience/codebase.

“With respect to the interface of Expression Web and the Expression products–our objective is to unify the Expression applications under a single UI framework. As you can imagine, with a program having a lot of native, Win32 code, it’s a challenge to port that code base to a new UI paragidm. Expression Web 3 is our first, significant step in that direction. As folks have noted, SuperPreview (as it was written from scratch), uses the Blend UI framework. The Expression Web 3 UI uses significant parts of this framework to achieve it’s look and feel. All the new features (Insert Silverlight, Silverlight Video, Deep Zoom) are built with the Blend framework (you can tell by the dialogs). However, there are still quite a few remaining Win32 dialogs. These will be ported in future versions of the application until Expression Web is fully integrated into the framework.”

According to somasegar’s blog Expression Web 3.0 will be out this Summer, so you can upgrade your Microsoft Expression 2.0 to 3.0 and get much great features with Microsoft Expression 3

Features Microsoft Expression 3

Now, we will discuss what are the new features in the Microsoft Expression 3

• Create compelling Websites visually
  You can make design decisions on the fly, knowing that you're seeing a faithful representation of the final browser-rendered page.


• Create standards-based Website more quickly and easily
Expression Web speeds the essential task of cross-browser debugging. With SuperPreview, you don’t need a Web service to debug your pages on the same machine that you use for development. SuperPreview not only shows a high-fidelity rendering of how pages will look on different browsers, but it also identifies the element’s tag, size and position, applied styles, and location in the DOM (Document Object Model) tree so you can quickly fix the error


• SuperPreview
  SuperPreview is a tool that shows how pages display in multiple browsers and helps diagnose the root cause of any display differences.
  
• Snapshot Preview
  SuperPreview is a useful feature if you want to use a comprehensive set of tools to validate that your web page appears as desired in multiple browsers

ASP.NET Dynamic Data

ASP.NET Dynamic Data Introduction

Many definition about ASP.NET Dynamic Data.

ASP.NET Dynamic Data is a web application scaffolding framework from Microsoft, shipped as an extension to ASP.NET, that can be used to build data driven web applications. It exposes tables in a database by encoding it in the URI of the ASP.NET web service, and the data in the table is automatically rendered to HTML. The process of rendering can be controlled using custom design templates. Internally, it discovers the database schema by using the database metadata.

ASP.NET Dynamic Data is a framework that lets you create data-driven ASP.NET Web applications easily. It does this by automatically discovering data-model metadata at run time and deriving UI behavior from it. A scaffolding framework provides a functional Web site for viewing and editing data. You can easily customize the scaffolding framework by changing elements or creating new ones to override the default behavior. Existing applications can easily integrate scaffolding elements with ASP.NET pages.

That definition was take from msdn.microsoft.com and wikipedia.org for comparison. So, what are the definition from ASP.NET Dynamic Data. ASP.NET Dynamic data is new controls for DetailsView, FormView, GridView, or ListView controls along with a lot of meta-infrastructure classes to make it possible. The design uses convention over configuration in a number of places, and this marks, IMHO, the recognition of a simpler way to do things.

ASP.NET Dynamic Data brings major usability and RAD development changes to the existing ASP.NET data controls. RAD development is significantly increased by the use of a rich scaffolding framework. After you add a LINQ to SQL or Entity Framework data model to a project, you can simply register it with Dynamic Data. The result is a fully functional Web site. Full CRUD (create, read, update, and delete) operations are supported. The site includes filtering by foreign keys and Boolean fields; foreign keys are automatically converted to their friendly names. Smart validation is automatically available, which provides validation based on database constraints for nullable fields, data type, and field length.

ASP.NET Dynamic Data Features:

• The ability to render data by defining templates, either at the page-level (for example, to define default renderings for list, details, edit, and insert pages) or the field-level (for example, to define default renderings for different data field types or foreign key relationships). This feature allows you to update data templates in a single location, which will take effect across your entire site for the various objects/schema in your data model.


• The ability to specify metadata on the data model that defines custom validation rules or display hints. The metadata that you define on the model results in custom behavior for performing rendering (for example, which field template to use on a given column/property) as well as custom validation logic in your Website UI and also when the data model is used programmatically from code.


• Support for more data access layers - ADO.NET Data Services (formerly Astoria);
  Custom Business Logic Layer


• Field Templates - URL, E-mail, and Enumeration


• Entity Templates - Automatic tempalates for ListView, FormView; Template based on entity instead of field


• Inheritance Support (EF and Linq2SQL)


• QueryBlock - Rich Declarative Linq Expressions


• Rich Filtering - Attributes and templates


• MVC Support

ASP.NET MVC Framework

What is MVC ?

Model–view–controller (MVC) is an architectural pattern used in software engineering. Successful use of the pattern isolates business logic from the user interface, permitting one to be freely modified without affecting the other. The controller collects user input, the model manipulates application data, and the view presents results to the user. Typically, views and controllers come in pairs, each corresponding to a small part of the user interface; an application will likely be built with many pairs.

ASP.NET MVC Framework

ASP.NET MVC Framework is a Model-view-controller pattern which Microsoft added to ASP.NET. It allows software developers to build a Web application as a composition of three roles: Model, View and Controller. A Model represents the state of a particular aspect of the application. Frequently, a model maps to a database table with the entries in the table representing the state of the table. A Controller handles interactions and updates the model to reflect a change in state of the application. A View extracts necessary information from a model and renders a user interface to display that.

Benefit of ASP.NET MVC Framework :

• Provides complete control over your HTML markup
  
• Enables rich AJAX integration
  
• Intuitive website URLs
  
• Clear separation of concerns which results in web applications that are easier
  
• to maintain and extend over time.
  
• Testability – including support for test-driven development.


• MVC is a very testable framework and you get full control of the rendering process. You can add functionality if you want, because MVC is very extensible and you can create a clean, DRY, testable web application. Phil Haack (the program manager of ASP.NET MVC) did a great presentation at the PDC.


• Separation of Concerns and the resulting testability


• Better control over HTML in MVC views (compared to classic Web Forms). Rendering using HTML helpers provided for MVC View Pages.


• Nice looking logical URLs


• Productivity features like binding of HTML form fields to action method arguments and declarative authorization rules (by decorating action methods)

ASP.NET vs ASP Classic

What is ASP.NET ?

ASP.NET attempts to simplify developers' transition from Windows application development to web development by offering the ability to build pages composed of controls similar to a Windows user interface. A web control, such as a button or label, functions in very much the same way as its Windows counterpart: code can assign its properties and respond to its events. Controls know how to render themselves: whereas Windows controls draw themselves to the screen, web controls produce segments of HTML and JavaScript which form part of the resulting page sent to the end-user's browser.

ASP.NET encourages the programmer to develop applications using an event-driven GUI model, rather than in conventional web-scripting environments like ASP and PHP. The framework attempts to combine existing technologies such as JavaScript with internal components like "ViewState" to bring persistent (inter-request) state to the inherently stateless web environment.

What is ASP ?

Active Server Pages or ASP, as it is more commonly known, is a technology that enables you to make dynamic and interactive web pages.

ASP uses server-side scripting to dynamically produce web pages that are not affected by the type of browser the web site visitor is using.

The default scripting language used for writing ASP is VBScript, although you can use other scripting languages like JScript (Microsoft's version of JavaScript).

ASP pages have the extension .asp instead of .htm, when a page with the extension .asp is requested by a browser the web server knows to interpret any ASP contained within the web page before sending the HTML produced to the browser. This way all the ASP is run on the web server and no ASP will ever be passed to the web browser.

Any web pages containing ASP cannot be run by just simply opening the page in a web browser. The page must be requested through a web server that supports ASP, this is why ASP stands for Active Server Pages, no server, no active pages.

As ASP was first introduced by Microsoft on it's web server, Internet Information Services (IIS), that runs on Windows 2000/XP Pro/NT4, it is this web server that ASP pages usually run best on.

For those of you running Windows and wish to play around with ASP on your own system you will need to install Microsoft's Internet Information Services (IIS). Lucky IIS or its micro version Personal Web Server (PWS) comes free with Windows.


compared ASP.NET to ASP classic are:

• Compiled code means applications run faster with more design-time errors trapped at the development stage.
  
• Significantly improved run-time error handling, making use of exception handling using try-catch blocks.
  
• Similar metaphors to Microsoft Windows applications such as controls and events.
  
• An extensive set of controls and class libraries allows the rapid building of applications, plus user-defined controls allow commonly-usedweb template , such as menus. Layout of these controls on a page is easier because most of it can be done visually in most editors.
  
• ASP.NET leverages the multi-language capabilities of the .NET Common Language Runtime, allowing web pages to be coded in VB.NET, C#, J#, Delphi.NET, Chrome etc.
  
• Ability to cache the whole page or just parts of it to improve performance.
  
• Ability to use the code-behind development model to separate business logic from presentation.
  
• If an ASP.NET application leaks memory, the ASP.NET runtime unloads the AppDomain hosting the erring application and reloads the application in a new AppDomain.
  
• Session state in ASP.NET can be saved in a Microsoft SQL Server database or in a separate process running on the same machine as the web server or on a different machine. That way session values are not lost when the web server is reset or the ASP.NET worker process is recycled.
  
• Versions of ASP.NET prior to 2.0 were criticized for their lack of standards compliance. The generated HTML and JavaScript sent to the client browser would not always validate against W3C/ECMA standards. In addition, the framework's browser detection feature sometimes incorrectly identified web browsers other than Microsoft's ownInternet Explorer as "downlevel" and returned HTML/JavaScript to these clients with some of the features removed, or sometimes crippled or broken. However, in version 2.0, all controls generate valid HTML 4.0, XHTML 1.0 (the default) or XHTML 1.1 output, depending on the site configuration. Detection of standards-compliant web browsers is more robust and support forCascading Style Sheets is more extensive.
  
• Web Server Controls: these are controls introduced by ASP.NET for providing the UI for the web form. These controls are state managed controls and areWYSIWYG controls.

Microsoft Expression 2 Features

Microsoft Expression Web (EW) is the tool that has replaced FrontPage as Microsoft's web design tool. Microsoft Expression Web is a proficient design tool to create contemporary, standards-based websites that not only deliver superior quality but also encourages creativity.

Microsoft Expression Web is a ’WYSIWYG’ HTML editor as well as a graphical web design program by Microsoft that has today replaced the legacy program Microsoft FrontPage. Expression Web is a part of the Expression Studio suite.

Expression Web provides support for integrating XML, XHTML, XSLT, CSS 2.1, ASP.NET 2.0 and other standard Web technologies into the websites.

Creating websites that conform to the internationally recognized standards was never felt that important over the past. But over the last year the term Web 2.0 has come to represent the new era of Web Technologies offered to designers, developers and web designers. This new age is built on standards. Expression Web contains all the tools you need to achieve that endeavor. There are design standards, such as Cascading Style Sheets; metadata standards; data transfer standards, such; and accessibility standards for visually impaired. XHTML builds upon HTML standards to provide the mechanism that allows browsers to properly encode and display your web pages. Expression® Web can write fully compliant XHTML code. Design tools for the Web artist are needed to support these standards.

Expression features
In line with the team’s commitment to short release cycles, Expression Studio 2 is coming to market one year after the last release with major updates to each product. The products together contain more than 100 new features and introduce new Microsoft Silverlight functionality for creating stunning cross-browser, cross-platform Web experiences.

ASP.NET User Control

ASP.NET User Control Introduction

ASP.NET supports creating reusable components through the creation of User Controls. A User Control follows the same structure as a Web Form, except that such controls are derived from the System.Web.UI.UserControl class, and are stored in ASCX files. Like ASPX files, an ASCX file contains static HTML or XHTML markup, as well as markup defining web control and other User Controls. The code-behind model can be used.

User can also build Custom Controls for Asp.Net application. Where controls are in compiled DLL file. And by using Register directive user can use control from DLL.

User controls are containers into which you can put markup and Web server controls. You can then treat the user control as a unit and define properties and methods for it.

An ASP.NET Web user control is similar to a complete ASP.NET Web page (.aspx file), with both a user interface page and code. You create the user control in much the same way you create an ASP.NET page and then add the markup and child controls that you need. A user control can include code to manipulate its contents like a page can, including performing tasks such as data binding.

A user controls differs from an ASP.NET Web page in these ways:

• The file name extension for the user control is .ascx.

• Instead of an @ Page directive, the user control contains an @ Control directive that defines configuration and other properties.

• User controls cannot run as stand-alone files. Instead, you must add them to ASP.NET pages, as you would any control.

• The user control does not have html, body, or form elements in it. These elements must be in the hosting page.

Benefit of Using User Control in ASP.NET
There are many benefits using user control in ASP.NET :

• The drag-and-drop design interface supported by user control is the simplest and fastest way to create your controls user interface.
• You can put any amount of server-side code behind a web user control, so you can have your Web Part perform any server-side processing that you want.
• You can give your Web Part custom web properties, methods, and evens, increasing flexibility of the Web Part.
• You can include client-side code and HTML in your Web Part along with ASP.NET WebForm controls and server-side code just by switching to HTML view.
• In addition to being more powerful than pure HTML, ASP.NET WebForm controls generate their HTML at run time and can configure the HTML they generate to match the device that is requesting time
  

Where can you find ASP.NET hosting with user control ?
Now, Webhostforasp.net support for user control in asp.net. Webhostforasp.net is one of the leading US hosting provider specialized with asp.net hosting and windows hosting.

ASP.NET 3.5 Hosting Technologies

What is Asp.net 3.5?

Asp.net 3.5 is the newest version that microsoft offer. On September 19, 2007, microsoft realesed the ASP.NET 3.5 with visual studio 2008.

Any Different with Asp.net 3.5 and Asp.net 3.0?

Sure, it's must be has different theres 2 atleast we got from Asp.net 3.5 and Asp.net 3.0.

1. Integration Ajax Extension

2. Control ListView

3. Control DataPager

4. Language Integrated Query (LINQ)

Integration Ajax Extension

Before we discuss about Integration Ajax Extension, we should know what is Ajax. Ajax (Asynchronous JavaScript and XML) is arguably one of the most hyped technology acronyms around. The advantage of using Ajax is that the pages refreshes can be minimized, allowing users to get the information they need quickly and easily through a more rich and functional interface.

Asp.net ajax product used to be separate installation that you required to install on your mechine and the web server that you working with. Now, Asp.net ajax extension just a part of asp.net framework. When you create a new Web application, you do not have to create a separate type of ASP.NET application. Instead, all ASP.NET applications that you create are now AJAX-enabled.

What is Control ListView?

The ListView control supports the data editing, insertion, deleting, and sorting semantics of higher-level controls like the GridView. But, unlike the GridView - it provides you with complete control over the html markup generated.The ListView control can build for page of catalog product. There are some advantage in sorting, grouping, and update, that ListView have than Repeater or DataList

Example for control ListView

What is Control DataPager?

DataPager is an external control to provide paging features. Otherwise, the listview doesn't support paging, so the DataPager serves as an external control to provide paging features.

The advantage of seperate control is that it gives more control about what pager look like and where it can be place on the page.

The DataPager class is used to page data and to display navigation controls for data-bound controls that implement the IPageableItemContainer interface.

The big change with DataPager is that it is decoupled from data-bound control it provides paging support for.

Example of DataPager



What is LINQ ?

LINQ is a query that integrated with language. That means, now C# programming language has a new feature for support query to data source.

The LINQ technology provides a set of extensions to the .NET framework that allow the developers to use .NET language that their choice to issue queries against any data source.

LINQ's great strength is that it offers a uniform approach to query, via:

• LINQ to Objects - querying a collection of objects


• LINQ to SQL - for managing and querying relational data, as objects.


• LINQ to XML - for querying XML
