    Why we have built RadDomainDataSource for Silverlight?

    Although Rossen has stated almost all of the things in his introductory blog post about RadDomainDataSource I wanted to create a separate blog entry which answers the most important question that you might be asking: “Why Telerik have developed their own version of a domain data source component?” Here is the answer: We felt your pain We have received numerous forum posts and support tickets stating that you want a codeless approach to data-binding that supports most common data operations without the need for any custom code. During the times when RadDomainDataSource was not available you will have to write hundreds of lines of code in...

    OData support in RadGridView for Silverlight and WPF: The Netflix Catalog

    The Open Data Protocol – the other Microsoft data access strategy along with WCF RIA Services, did not gain as much as popularity as its RIA cousin (yet!). But here in Telerik we want to give you as much freedom and power as possible and this means making it extremely easy for our clients to access and manipulate their data in applications built with our components. Our RadDomainDataSource is coming soon, but is only one piece in the puzzle of enhanced data support in our controls – starting with RadControls for Silverlight and RadControls for WPF Q3 2010 it’s as simple as pie...

    Maintaining page state with MEF

    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...

    Implementing logical paging with RadDataPager for WPF and Silverlight

    Following the great series about RadDataPager started by Rossen and Pavel today I’m going to show you how to implement logical paging. We are going to implement alphabetical paging similar to this ASP.NET AJAX Grid Demo. As you may already know the key to the heart of the RadDataPager is the IPagedCollectionView interface. You can create your own implementations of this interface and implement any custom logic for paging you want. This is exactly what we are going to do in this article. Introducing PagedCollectionViewBase and LogicallyPagedCollectionView<T> If you have looked at IPagedCollectionView interface you may have found out that it is not a trivial interface to...

    MicroModels for Silverlight

    Last week I was impressed by Paul Stovell’s marvelous project – MicroModels. In a nutshell a micro model is a view model over your objects, which allow you to define dynamic properties, collection and commands. You can read more about it in Paul’s introductory blog post here. Despite its great features, “MicroModels” has one big limitation - it does not run in Silverlight. And this is where my journey began. My mission was to port the code to Silverlight with little to no modifications. Porting the code to Silverlight The task was not an easy one, but after a lot of head scratching...
