MEF to the rescue in Task-it
Task-It Series This post is part of a series of blog posts and videos about the Task-It (task management) application that I have been building with Silverlight 4 and Telerik's RadControls for Silverlight 4. For a full index of these resources, please go here. One of the posts listed in the index provides a full source download for the application. Intro to MEF One of the frameworks that I chose to leverage in the development of my Silverlight 4 Task-It application is MEF, the Managed Extensibility Framework. Actually, that decision came while I was at a Silverlight ‘Deep Dive’ session on the Microsoft campus in Redmond, WA, and...March 17, 2010 -

Changing Silverlight application themes at runtime
We have received a lot of questions how can the application theme be changed at run time. The most important thing here to mark is that each time the application theme is changed all the controls should be re-drawn. Without going into too much detail, we could explain the application themes as a mechanism to replace the content of the Generic.xaml file in every loaded Telerik assembly at runtime. This does not affect the controls that already have default style applied, hence the need to create new instances. Because in the Silverlight applications the RootVisual cannot be changed at run time, we...March 17, 2010 -
Web ASP.NET AJAX
Common reasons for the ‘Sys is undefined’ error in ASP.NET Ajax applications
In this blog I will try to summarize the most common reasons for getting the famous 'Sys is undefined' error when running an Ajax enabled web site or application (there are almost one million results on Google for that phrase). Where does it come from? In every Ajax web page’s source you will see a code like this: <script type="text/javascript"> //<![CDATA[ Sys.WebForms.PageRequestManager._initialize('ScriptManager1', document.getElementById('form1')); Sys.WebForms.PageRequestManager.getInstance()._updateControls([], [], [],...March 16, 2010

Telerik is First to Announce Support for Microsoft Silverlight Analytics Framework
Yesterday at MIX 10 conference Microsoft announced the Microsoft Silverlight Analytics Framework Beta. The Silverlight Analytics Framework (SAF) is a new open-source framework to allow designers and developers to integrate web analytics into Silverlight applications in a consistent manner. Supporting out-of-browser and offline scenarios, Microsoft built this framework in conjunction with a number of web analytics services and control vendors to support multiple analytics services simultaneously without degrading application performance. Because the SAF is enabled as a set of behaviors in Microsoft Expression Blend, designers and developers can visually instrument their designs and configure A/B testing rapidly without...March 16, 2010 -

Restyling RadDataPager for WPF and Silverlight
A small but powerful control has joined the great family of Telerik XAML controls with the recent release. RadDataPager is a result of an increasing demand from our customers who needed to work with large amounts of server data presented in small portions at the client side. The primary goal was to make a powerful data paging control to be used in any scenarios requiring getting and presenting portions of data. How good is RadDataPager in working with paged data you can see in Rossen's announcement. Yet being a XAML control it challenged us...March 16, 2010 -

Silverlight Recruiting Application Part 4 - Navigation and Modules
After our brief intermission (and the craziness of Q1 2010 release week), we're back on track here and today we get to dive into how we are going to navigate through our applications as well as how to set up our modules. That way, as I start adding the functionality- adding Jobs and Applicants, Interview Scheduling, and finally a handy Dashboard- you'll see how everything is communicating back and forth. This is all leading up to an eventual webinar, in which I'll dive into this process and give a honest look at the current story for MVVM vs. Code-Behind applications. (For...March 15, 2010

Using Telerik’s new LINQ implementation to create OData feeds
This week Telerik released a new LINQ implementation that is simple to use and produces domain models very fast. Built on top of the enterprise grade OpenAccess ORM, you can connect to any database that OpenAccess can connect to such as: SQL Server, MySQL, Oracle, SQL Azure, VistaDB, etc. While this is a separate LINQ implementation from traditional OpenAccess Entities, you can use the visual designer without ever interacting with OpenAccess, however, you can always hook into the advanced ORM features like caching, fetch plan optimization, etc, if needed. Just to show off how easy our LINQ implementation is to use, I will walk you through building an OData feed using...March 13, 2010

Demystifying the new OpenAccessContext Object
Today we had a great turn out for the Q1 2010 What’s New in OpenAccess, and JustCode webinar. However, we got a great deal of questions at the end so I am going to do my best to cover all of these questions here on my blog :) This entry will aim to better explain the context object you saw me use in the webinar, and hopefully clarify a few things for everyone. The first couple of question I want to answer are below. 1. So are we basically throwing out the old way of OpenAccessing data?....don't need to create scopes,...March 13, 2010
