It's Thursday once again and that means we have a fresh new installment of XAMLflix for you. Today we'll be covering RadBulletGraph, a quick and easy to use data visualization component used for comparing several values as well as for showing projections on data, all at a glance.

For a quick recap, XAMLflix = Videos + Projects covering all of the controls in both the RadControls for Silverlight and RadControls for WPF control suites. We are revamping the entire video library with fresh new content based on the latest and greatest versions of our controls, complete with projects so you can...

What better way to spice up your Wednesday than by checking out some videos on one of the hot new controls in the RadControls for Silverlight and RadControls for WPF control suites? I certainly can't think of one! RadDataBars allow for a quick and easy display of data in a readable format, perfect for displaying KPIs or other business-centric data within your applications when what you need is an easy way to compare values or track progress over time.

For a quick recap, XAMLflix = Videos + Projects covering all of the controls in both the RadControls for Silverlight and RadControls for WPF control suites....

During the previous episode we explored some of the controls that are being used within the CRM demo, including RadDomainDataSource, RadSparklines, RadUniformGrid, and RadCoverFlow, but don’t think we stopped there with uses for the RadControls for Silverlight suite. All of those were found within a single view of a single module, helping to better streamline development and provide the performance and functionality we are looking for, but that leaves quite a few other modules to cover. Since we’ll be seeing it pop up more than a few times, I thought it would be best to take a look...

A week after the official release of RadTimeBar for Silverlight and WPF with the Q1 2011 SP1 release, we have some fresh new resources ready for you to watch to start getting the hang of working with RadTimeBar and integration with other RadControls.

Last week I blogged about the Official Release of RadTimeBar, which included walking through some examples and some sample code.  But some of you would rather see it in action along with an expert voice on how this integration can take place - and we heard you!  We have just published three new videos up to Telerik TV...

When we rolled out the Q1 2011 release, there was a surprise control that we included in the release as a Beta version – RadTimeBar.  This control is useful for scenarios where you require a birds-eye view of your time-based data, be it sales history, support volume, or any other statistic that you might want to track over a longer period of time.

The real value in the RadTimeBar control, however, is in the integration scenarios that it offers with other controls from RadControls for Silverlight and WPF.  By utilizing data-centric controls like RadGridView and RadChart with the RadTimeBar, your “birds-eye view”...

In addition to the fact that our next release focuses mostly on our accessibility and automated testing as described in this blog post, in our upcoming version we will include many bug fixes in all RadControls for WinForms, including a highly optimized version of RadTreeView.

In this article however, we want to present a new interesting feature in RadGridView that you will surely find useful. A customer of ours requested a mixed hierarchy mode where he wanted to use a self-reference hierarchy AND the classic hierarchy mode together. The scenario that he described used a file explorer where the main level...

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...

In our previous blog post we showed how to use the new RadGridView Object-Relational Hierarchy with the Entity Framework. The same scenario can be easily implemented with Telerik OpenAccess ORM. The OpenAccess wizard for adding a new DomainModel will help us build the model of the well-known Northwind database in a few easy steps:

Once this is done, the auto-generation of the hierarchy is very simple and needs just a few lines of code. We only need the LINQ query to the root object used for a DataSource (in our case “Suppliers”) and then setting AutoGenerateHierarchy to true:

Another four months have gone by and another awesome release of RadControls has arrived!

One of the exciting new features in this release are the so-called 'Expression Descriptors'. Previously, whenever our clients wanted to filter data but needed even more control than our good old FilterDescriptor could provide, they had to subclass it and override some of its methods. Even though that approach works, it is tedious and cumbersome. And, as much as LINQ Expressions rock, having to manually generate expression trees by hand... yuck!

The new FilterDescriptor<T> allows you to directly plug a predicate that determines which items are filtered. You...
