Overview of this book

Silverlight is a powerful development platform for creating engaging, interactive user experiences for the Web, desktop, and mobile applications. Integrating Silverlight RIAs in SharePoint 2010 offers amazing opportunities to combine the power and flexibility offered by SharePoint. It is easy to create great user experiences when you have a step-by-step guide to implement Silverlight 4 applications on SharePoint 2010 sites. This book is not a primer on Silverlight 4 or SharePoint 2010. This book focuses on the integration of Silverlight 4 and SharePoint 2010 and provides step-by-step guidelines for implementing Silverlight RIAs in SharePoint. It is filled with real-world examples that depict the various techniques for interacting with data and services provided by this powerful business collaboration platform, for the enterprise and the Internet. As you sit reading this, you might have already started thinking about the benefits of implementing multiple Silverlight applications in a SharePoint environment. This book will help bring those thoughts to fruition. This book begins with the fundamental concepts of integrating Silverlight 4 with SharePoint 2010, such as the preparation of the development environment to create applications using Silverlight 4 and the addition of one or more Silverlight RIAs to a SharePoint site. Then, it moves on to the SharePoint Silverlight Client Object Model world, using step-by-step examples to combine a Silverlight application and a SharePoint module. It also covers methods to deploy and debug the Silverlight application while it runs as Silverlight Web Part in a SharePoint page. The book teaches you to take advantage of the new features offered by Visual Studio 2010 to browse SharePoint lists. Once the reader has control over the SharePoint Silverlight Client Object Model and its asynchronous operations in Silverlight applications, it is time to access external databases through the new Business Connectivity Services (BCS) and interact with workflows. Then, the book explains to perform CRUD operations by consuming the new SharePoint 2010 WCF Data Services in Silverlight. In the end, you'll learn to utilize Silverlight 4's rich media features to add effects and interactive animations to images and videos, thus offering the final touches to the Silverlight 4 and SharePoint 2010 integration learning experience. By the end of this book, you'll learn to take advantage of the unique features offered by Silverlight in order to create impressive UX that interact with SharePoint 2010.

Preface

Analyzing Web Parts with SharePoint Developer Dashboard


We are going to use another alternative to retrieve information for the user assigned to each item. We can avoid running many complex asynchronous executions to retrieve the user for each item in the ProjectsList2010 list. Follow these steps to retrieve the user related to each item in the ProjectsList2010 list by using a LINQ to objects query to perform a join on two lists.

  1. 1. Stay in Visual Studio as a system administrator user.

  2. 2. Open MainPage.xaml.cs and replace the code in the ShowProjects method with the following lines. This time, it will run two asynchronous queries to retrieve all the items for the ProjectsList2010 and UserInformationList lists. Then, it will perform a LINQ to objects query to retrieve the Name value for the user assigned to each task in the ProjectsList2010 list.

    // IMPORTANT NOTE: DataServiceQuery doesn't support join
    // This is another alternative to the previous examples
    // Declare the LINQ query to retrieve...
