In the last episode we were examining a creative approach that the development team behind the CRM demo incorporated for connecting views to their Prism regions using a combination of custom attributes, attached behaviors, and the managed extensibility framework (MEF). One of the commenters was a little critical of the ‘magic’ behind MEF, and rightly so as many of us like being able to trace the exact line that code will go through as opposed to relying on the magic of composition to work everything out for us. Today we bring you one of those unexpected issues in which the...

The last time we all got together was before a little conference known as Build. Everyone learned a ton of information about what is coming next in Windows 8 and the WinRT platform, but one thing stuck out for sure – Metro is in. Thankfully our designers have been all over this for quite a while and we have some very nice things in the works, most of which I can’t publicly talk about (yet!), but in the terms of this application we’re definitely on the right track. And don’t forget, an investment in a Silverlight application today means...

In Q2 we introduced the first official version of RadRichTextBox for Silverlight. In this blog post we want to share with you one of the main principles which we have followed while developing our brand new rich text editor for Silverlight - total extensibility.

One of the key features which we have included is the ability to import/export from/to various document formats. For the first release we have already included some of the most widely used formats, such as .html/.docx/.xaml/.txt and in the next releases there are still more to come. As MEF is a wonderful technology, we have built...

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, and I will be referring to that source code in this post.

The page state issue

One of the great things about MEF is that it allows you to maintain state across pages. So basically, when a user spends some time on a page and makes some changes, then...

In my MEF into post, MEF to the rescue in Task-It, I outlined a couple of issues I was facing and explained why I chose MEF (the Managed Extensibility Framework) to solve these issues.

The first issue was the fact that my application...

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...
