The video below is from a webinar that I presented on the RadTreeView for WPF.  The webinar covered some of the basic functionality of the RadTreeView and should give you a good understanding of how to get started with the RadTreeView.  While this webinar is focused on the WPF version of the RadTreeView control, the content is also relevant to the Silverlight version as...

It’s often necessary to modify or format some of the raw data received by your data tier application or other data sources. In Silverlight, you can create your own value converter and introduce your own formatting rules. In this blog post I will create a simple value converter that formats double values, and then use it with a RadComboBox. First, let’s create a class that will represent our data source. The equivalent of this class in more realistic scenario would be a proxy class generated by your data tier application in case you use RIA services.     public class Data : List<Item>       {           public Data()           {               this.Add(new Item() { Name = "Ferrari", Price = 120000 });               this.Add(new Item() { Name = "Mercedes", Price = 100000 });...

Telerik RadControls for Silverlight provide a very powerful ContextMenu control, that supports right click, modifier keys and that can be easily attached to any visual element. In this article I will show how to attach RadContextMenu to a data-bound RadTreeView and perform actions on the clicked treeview items, depending on the selection in the context menu. For simplicity, here I will use a treeview, bound to a static collection, but it can be easily extended to load its items from a web service: <UserControl x:Class="ContextMenuInTreeView.Page" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:ContextMenuInTreeView" xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls" xmlns:telerikNavigation="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Navigation"> <UserControl.Resources> <local:DataViewModel x:Key="ViewModel" /> <telerik:HierarchicalDataTemplate x:Key="TreeViewItemTemplate" ItemsSource="{Binding Children}"> <TextBlock Text="{Binding Text}"> <telerikNavigation:RadContextMenu.ContextMenu> <telerikNavigation:RadContextMenu> <telerikNavigation:RadMenuItem Header="New Child" /> <telerikNavigation:RadMenuItem Header="New Sibling" /> <telerikNavigation:RadMenuItem Header="Delete" /> </telerikNavigation:RadContextMenu> </telerikNavigation:RadContextMenu.ContextMenu> </TextBlock> </telerik:HierarchicalDataTemplate> </UserControl.Resources> <StackPanel Background="White" DataContext="{StaticResource...

CustomBuildTask.zip If you are working on a large project it is very probable that the project is composed of several parts/modules which are build separately. What are your options if you want to be able to rebuild the whole thing easily? If you are a Quake tournament winner equipped with Razer Copperhead mouse you could probably schedule 10 builds (in the right order) in a matter of seconds but what about your colleagues that are not so gifted? Well, there is the TfsBuild command line tool but in case you are using the 2008 version and you would like to have the...

This June, I will be at the CodeStock conference in Knoxville, TN.  If you live in the area, then CodeStock offers you a great opportunity to learn about a variety of technologies.  I am honored to have been invited to sit on a panel discussion about running community conferences and user groups.  The conference will take place June 26-27 and only costs $25 if you get your tickets before June 1.  CodeStock is doing something very unique this year in allowing anyone who registers before May 15 to vote on the sessions they most want to see.  So you can actually...
