In this example I will show you how to populate a RadTreeView using LINQ and WCF. Also you will see how to transform a flat data into a hierarchical one. The target result is: 1. Create a new Silverlight Web Application Project NOTE: Make sure you choose "Web Application Project" After the project loads you can see that besides the regular Silverlight application, Visual Studio adds a Web application that will host the .xap file.   Before writing any LINQ or creating any WCF service, we need a database to target. 2. Right-click on RadTreeViewWithWCFWeb project and add a new item - "SQL Server Database". You can give the...

With this Beta2 release RadControls for Silverlight has been enhanced with several brand new controls:   RadTimePicker RadTimePicker is an easy to use control allowing you to integrate time selection in your web applications.

RadExpander  RadExpander control is a flexible control that helps you save space and achieve an easier navigation through...

Before we can begin any serious coding of the recently introduced "dotNetRegister" reference app, we need to define some some requirements. As with any good agile development effort, I want to create a backlog of features that need to be implemented and then prioritize development from there.

ASIDE: If any of these agile terms- like backlog, sprint, or burn-down rate- are unfamiliar to you, I highly encourage you to spend a little time becoming more...

Over the past several weeks I started a new video series, called RadTips, which demonstrates how to use specific features of Telerik controls. The first four episodes of the series was dedicated to the new client-side data binding feature of the RadGrid for ASP.NET AJAX. This feature is only available with the RadControls for ASP.NET AJAX Q2 2008, our latest release of the control suite. Each episode showed how to implement a specific RadGrid feature when binding to data on the client. If you haven't had a chance to watch them, I highly recommend taking a few minutes to check...

It's finally out! As promised, we compiled this cool demo that uses a very simple but slick carousel UI. Now you can just give it a spin! The download contains updated versions of several other Telerik Windows Forms demos that we have recently added to our portfolio, such as a RadGridView exporting demo, which features our great Telerik.Reporting solution: I'll be very glad to have your feedback on this. Have fun!...
