TreeView Drag Drop in Silverlight
I have seen plenty of questions around drag-drop operations within a TreeView and I thought of dedicating a post to it. Now usually when one thinks of implementing a Drag Drop operation on a TreeView, there are a couple of events like the DragEnter, DragLeave, DragOver and Drop that are to be raised and handled.
In some cases, you must also cancel the drag-n-drop operation if the drop is invalid. Overall, this looks like a lot of work for a developer who wants to quickly implement drag-n-drop functionality on his/her controls.
With the addition of the drag-drop targets for controls like the TreeView (and some others like the ListBox, DataGrid and DataPointSeries), doing a drag and drop operation in a TreeView is a cakewalk.

Silverlight Introduction
This article will be very helpful for the beginners who want to know and start development on Silverlight projects, if you are already working on Silverlight you will find complete understanding of Silverlight Introduction. In this article I have started with definition of Silverlight, purpose of the Silverlight technology and different versions released so far. You will also see development tools required to work with Silverlight. End of this article you will get the complete introduction of Silverlight.
What is Silverlight? Silverlight is the new Microsoft technology on web platform for Rich Internet Applications (RIA) launched by Microsoft in 2007.Silverlight supports multiple browsers called cross-browser technology, which includes Internet Explorer, Firefox, and Safari, opera etc…Silverlight supports multiple Operating Systems called cross-platform technology, which includes Windows family of OS, Mac, and Linux with moonlight technology (Moonlight is an open source implementation of Silverlight, primarily for Linux and other Unix/X11 based operating systems).Silverlight is also supports multiple devices called cross-device technology, which include mobile devices to desktop browsers to 720p HDTV video modes etc…
Silverlight is a browser plug-in approximately 4MB in size, it is client side free software for easy and fast less than 10 sec one time installation available for any client side browsers.Silverlight supports the display of high-definition video files, and sending them over the Net. Silverlight applications are delivered to a browser in a text-based markup language called XAML. XAML is a declarative markup language that you can use to define the UI elements for your Silverlight-based application.Silverlight is considered as a competitor to Adobe’s flash technology.One of the design goals of the Silverlight technology is to fill the gap between windows application and web application in terms of creating Graphical User Interface (GUI). So far web developers were not able to make client happy in terms of UI, but now web developer will be able to full fill this with the help of Silverlight technology. Why Silverlight?
Here is the list of advantage why we should go with Silverlight over the Flash and other technologies already available: Support of .NET framework – if you are already .NET developer it is easy to start programming on Silverlight.Support of Managed code – you can write programming in your favorite language which .NET CLR supports like C#,VB.NET, Dynamic languages(IronPython, IronRuby).Better development tools -Visual Studio 2010, Expression Blend.Large community- available lot of learning resource as compare to Flash technology.Integration with Enterprise based technologies like WPF, LINQ etc…Silverlight releases
Silverlight 1.0
This is the first release of Silverlight technology in 2007. There are lot of releases happened in initial stage of Silverlight technology, however later at end of the year 2007 final release of version 1.0 got released. Originally this release was called WPF/E, which stands for Windows Presentation Foundation/ Everywhere. This release consists of the core presentation framework, which is responsible for UI, interactivity and user input, basic UI controls, graphics and animation, media playback and DOM integration.
The Major drawback of this release is not supporting managed code, which means you can’t use .NET supported programming languages for manipulating GUI elements. This was managed by scripting programming languages like Java Script (Only interpretation no compilation), which is hard for non Java Script programmers.
Applications are written either completely in XAML or in a mix of XAML and JavaScript with DOM (Document Object Model) to manipulate the user interface. Since there is no managed code there is no compilation required only JavaScript is interpreted on the client (browser).
Silverlight application starts by invoking the Silverlight control from the HTML page, which then loads up a XAML file. The XAML file contains a Canvas object, which acts as placeholder for other elements. Silverlight provides various geometrical primitives like lines, ellipses and other shapes, to elements like text, images, and media etc.
Silverlight 2.0
After Silverlight 1.0 there are preview releases to fix bugs from initial release and improved performance issues then released Silverlight 2.0 in March 2008. We can consider this is the first release of the Silverlight for start application development because of lot limitations in Silverlight 1.0 and was not ready for developing applications efficiently. This is the exciting release to the developers, which supports managed code, living in the .NET world without managed code is very difficulty (actually not possible ). Silverlight 2.0 supports .NET programming languages like C#, VB.NET to write business logic or manipulate UI Elements at client side. Silverlight 2.0 is based on .NET Framework 3.5.
You can have a code behind file for every XAML (.xaml) file like ASP.NET (.aspx) pages to handle the business logic. It can be used to programmatically manipulate both the Silverlight application and the HTML page which hosts the Silverlight control. The XAML markup as well as the code, is compiled into .NET assemblies which are then compressed using ZIP and stored in a .xap file.
In this release Silverlight came up with own library, which is subset of .NET framework’s Base Class Library this included controls, components, support of web services and LINQ API features. It is also provides security, not to access Silverlight platform API from outside the world.
Features of Silverlight 2.0: Rich base class library: – This is a compatible subset of the full .NET Framework. It supports Collection, Reflection, Regular Expressions, String Handling, Data Access, LINQ etc…
Powerful built-in controls: – These include verity of controls :
o Extensible control base classes
o Common controls: Textbox, Checkbox, Radiobutton, TabControl, Slider, ScrollViewer, ProgressBar, Calendar etc…
ayout controls: Grid, StackPanel etc…
ata controls:DataGrid, etc..
Advanced skinning and templating support: – This makes it easy to customize the look and feel of an application.
Deep zoom: – which allows users to zoom into, or out of, an image (or a collage of images), with smooth transitions, using the mouse wheel.
Networking support:- Out-of-the-box support allows calling REST, WS*/SOAP, POX, RSS and standard HTTP services, enabling users to create applications that easily integrate with existing back-end systems.
Programming Languages:- including Visual Basic, C#, JavaScript, IronPython and IronRuby, making it easier for developers already familiar with one of these languages to repurpose their existing skill sets.
Cross-platform and cross-browser support: – This includes support for Mac, Windows and Linux in Firefox, Safari and Windows Internet Explorer.
Security: – Silverlight CoreCLR uses an attribute-based security model, as opposed to the Code Access Security (CAS) model of the desktop version of .NET Framework.

Adobe Flash is the most popular competitor to Silverlight both supports browser plug-in and enables execution of rich content for the Web. Flash is not the new technology, which is already having long life span as compared to Silverlight. But it does not have huge community as expected; it may be cause of limited development tools, which are not kwon to most of the developers. Flash uses ActionScript as programming language and Flex as programming environment, which most of the developer are far from these technologies.
For ASP.NET developers to extend their websites using flash content is not so simples, they need to learning development environment as mentioned above like ActionScript and Flex, apart from that there is no way to generate Flash content using server-side .NET code, which means it’s difficult to integrate ASP.NET content and Flash content.
Silverlight aims to give .NET developers a better option for creating rich web content. Silverlight provides a browser plug-in with many similar features to Flash, but one that’s designed from the ground up for .NET. Silverlight natively supports the C# language and uses a range of .NET concepts. As a result, developers can write client-side code for Silverlight in the same language they use for server-side code (such as C# and VB), and use many of the same abstractions (including streams, controls, collections, generics, and LINQ).

You have to make sure that the silver light reports you’re doing present the silver lining to those who are watching this. You can view the report even before you’re done. Check whether the data is in accordance with what you are presenting. With the silver light reports, you can manipulate the format. You can also toggle it so that it will zoom whenever you want it to.
The technology used in Silverlight reports has visually rich Web applications which make it quite appealing for the current generation. After all, people are used to technology nowadays and they prefer that everything gets better in each passing day. For example, Silverlight reports are regarded as the “Flash-killer”. Like Flash, Silver light reports can browse and even cross the web with not a lot of plug ins. It delivers the media that the current generation needs. After all, the Internet is filled with all these rich interactive applications.
Reports in silver light examine the accuracy of the data as well. The same rules used in PDF reports and even ASP reports are also used in these kinds of software. It is not enough to browse through the report and claim the data to be true without confirming these. Just because you have the program to help you with your report does not mean that you will be lax too. On your end, you need to confirm the accuracy of the data that you have at hand.
Silverlight report is a new reporting tool. This supports Microsoft Silverlight. The technology provides developers the ability to make effective and functional reports with these kinds of software. There are no limits to these – considering the interconnection that is brought by the web today.

How To Use Sql Server Reporting Services In Silverlight
You can use the Silverlight Viewer on applications that are situated on your html pages as well as with the applications that are out of your browser. There are many reasons as to why you may want to use this program. The first is that it allows you to print the reports right from Reporting Services using Silverlight. Second, this also has several features that you can use without much difficulty.
Usually, businessmen make use of the Silverlight Viewer for Reporting Services. This is a product that was first launched before the other applications that allows you to combine the Reporting Services and Silverlight. This program allows you to view the reports in Reporting Services with the utilization of Silverlight applications. This represents a control for Silverlight which is easily incorporated in any of the applications in Silverlight. In this case, it is possible for you to exploit the different sets of features which are available in standard desktop applications. These include dynamic scaling, smooth panning along with animation, sorting interactively, searching and many more.
In actuality, the chief obstacle of Silverlight being a development platform for businesses is that it lacks components that can be used in order for a businessman or a company to work with reports. In this case, it will be difficult for the organization to function effectively without the use of the right reporting system. Meanwhile, with the correct software that will allow you to accomplish the job of using the SQL Server Reporting Services in Silverlight, you can leverage the advantages of the two so that you can efficiently have your company’s own business intelligence application.
