At a special Firestarter event (part of which was and Telerik with the new Silverlight client for Facebook called "f!acedeck"), Microsoft unveiled what the next version of Silverlight will include. All I can say is that it will be a huge release - both in terms of easing the developer lives and for enabling even more rich user experiences (in-the-browser and especially out-of-browser). We can divide the new features that are coming in the runtime in two categories - 1) new media features and 2) features that are focused towards business application development. New Media features Hardware Decode and presentation of H.264 improve performance for lower-power devices to render...

Many of you have probably used Telerik's TreeView or going to do so in the future. One of its many features is the TriStateMode. In this blog post I'm going to explain how TriStateMode mode is designed to work and propagate the values up and down the tree. When in TriStateMode (IsTriStateMode=”True”) checking/unchecking an item makes the TreeView propagate the value. The value propagation actually checks/unchecks all items’ children and updates the chain of parents with appropriate value (checked, unchecked or undetermined). CheckState vs. IsChecked The TreeView exposes two properties used to manipulate items' check state - CheckState (of type ToggleState) and IsChecked...

The latest release of Silverlight - ver.4 was released earlier this year. For me this was the first Silverlight release that was stable and mature enough so that I could recommend to anyone building business applications to use it broadly. Now, six months later, we can see that the Silverlight adoption is very high and that there are a lot of great tools built with it. Regardless of all the recent comments and mostly speculations about the future of Silverlight I believe that this will be the primary MS platform for building applications for Windows and Mac in years to come. At MIX this year, the Silverlight platform was also introduced to...

Q3 2010 brings more slickness, better performance and new controls to RadControls for Silverlight/WPF to allow you develop your most interactive and richest Line Of Business applications. The latest major release includes new powerful data visualization controls, Data Virtualization for data-bound controls, supercharged RichTexBox and the most feature-rich and innovative ScheduleView control for WPF. RadSparklines Sparklines are intense, simple, word-sized graphics that bring context and history to numbers. Adding sparklines to the numbers in any report shows patterns and trends for those numbers, making the report much more useful for the end-user.   RadBulletGraph The BulletGraph is extremely useful in dashboards, or just any report, because it...

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...
