Last week (MIX 2011), Microsoft released the second Visual Studio Async CTP and I’ve decided to give it a try and implement one of my blog posts related to our Silverlight Data Virtualization with WCF RIA Services. To do this I’ve made two extension methods for DomainContext: LoadAsync<T>() and CountAsync<T>(). The first method will return the entities from a EntityQuery<T> and the second will return asynchronously count for the specified query.   And here is the result:   As you can see the only hardcoded value here is LoadSize for the virtual collection and everything else is retrieved and applied asynchronously using...

Every once in a while a customer will come to us and ask about a particular piece of functionality in one of the RadControls for Silverlight or RadControls for WPF that isn't covered in the demos, documentation, or videos. Just this week, one of the fans on our Telerik Facebook page did just that - specifically asking whether you could use a certain type of layout panel for the drag cue of RadDragAndDropManager.  Normally in a case like this, I want to say "Yeah, it's just a DataTemplate in Silverlight/WPF, so you could do almost anything there!" But we're developers, and code speaks...

As you can imagine, we use a lot of our own products internally - all our teams use our Agile Project Management software, Team Pulse; Sitefinity uses our ASP.NET AJAX tools, ORM and RadControls for Silverlight and Test Studio for automated functional and regression testing; Test Studio uses ORM, RadControls for WPF - and this does not even begin to touch upon the collaboration and cross product use here at Telerik. Well - why not showcase this - why not show how well the Telerik suite of tools can work together to boost your teams productivity? We thought we would start ...

In Part 1 of this series we covered how you can create an MVC (both MVC 2 and MVC 3) web application that is ready to be published to the cloud. Of course we also went through how you can make this application a Telerik application, taking use of our Visual Studio Extensions. What the application actually does is up to you of course, but now that you’ve finished developing everything you want to take it to the next level; you want to deploy! Launching to the cloud So your project is ready to rock and you’re eager to brag to everyone that...

As you may already know, we are working hard to improve the RadSlider in a broad way. We've fixed a lot of issues, but also added a lot of new cool features. Now it's so easy to customize and bind (in MVVM-ish way), that I've created this Windows 7 "Mixer" like example in less than an hour. I didn't change the Slider's ControlTemplate and don't have a single line of code behind. (Please note that the new slider will be available with the  beta of Q2.2011 ).
