I think telerik documentation tends to over complicate things. For example the help section for adding context menu to a radtreeview is insane. Binding this, binding that...really confused me. Luckily the demo code shows us an easy way. Don't forget to add the below attribute if you are using the <object> tag on your website, where the silverlight control is referenced.

<param name="windowless" value="true" />
<telerikNavigation:RadTreeView x:Name="RadTreeView1" Margin="10"
            <telerikNavigation:RadContextMenu.ContextMenu> 
                <telerikNavigation:RadContextMenu x:Name="contextMenu"
                    <telerikNavigation:RadMenuItem Header="Add New Item" /> 
                    <telerikNavigation:RadMenuItem Header="Remove Item" /> 
                    <telerikNavigation:RadMenuItem Header="Disable" /> 
                    <telerikNavigation:RadMenuItem Header="Enable" /> 
                </telerikNavigation:RadContextMenu> 
            </telerikNavigation:RadContextMenu.ContextMenu> 
            <telerikNavigation:RadTreeViewItem Header="Personal Folders" 
                    DefaultImageSrc="/TreeView/Images/Outlook/1PersonalFolders.png" 
                    IsExpanded="True"
                <telerikNavigation:RadTreeViewItem Header="Deleted Items(6)" 
                        DefaultImageSrc="/TreeView/Images/Outlook/2DeletedItems.png" /> 
                <telerikNavigation:RadTreeViewItem Header="Drafts" 
                        DefaultImageSrc="/TreeView/Images/Outlook/3Drafts.png" /> 
                <telerikNavigation:RadTreeViewItem Header="Inbox(14)" 
                        DefaultImageSrc="/TreeView/Images/Outlook/4Inbox.png" IsExpanded="True"
                    <telerikNavigation:RadTreeViewItem Header="Folders" 
                            DefaultImageSrc="/TreeView/Images/Outlook/folder.png" /> 
                </telerikNavigation:RadTreeViewItem> 
                <telerikNavigation:RadTreeViewItem Header="Junk E-mails" 
                        DefaultImageSrc="/TreeView/Images/Outlook/junk.png" /> 
                <telerikNavigation:RadTreeViewItem Header="Outbox" 
                        DefaultImageSrc="/TreeView/Images/Outlook/outbox.png" /> 
                <telerikNavigation:RadTreeViewItem Header="Sent Items" 
                        DefaultImageSrc="/TreeView/Images/Outlook/sent.png" /> 
                <telerikNavigation:RadTreeViewItem Header="Search Folder" 
                        DefaultImageSrc="/TreeView/Images/Outlook/searchFolder.png" 
                        IsExpanded="True"
                    <telerikNavigation:RadTreeViewItem Header="From Follow up" 
                            DefaultImageSrc="/TreeView/Images/Outlook/search.png" /> 
                    <telerikNavigation:RadTreeViewItem Header="Large Mail" 
                            DefaultImageSrc="/TreeView/Images/Outlook/search.png" /> 
                    <telerikNavigation:RadTreeViewItem Header="Unread Mail" 
                            DefaultImageSrc="/TreeView/Images/Outlook/search.png" /> 
                </telerikNavigation:RadTreeViewItem> 
            </telerikNavigation:RadTreeViewItem> 
        </telerikNavigation:RadTreeView> 
 

This works great for me. I don't see why a <user.resources> section is used in the documentation. Adds more complexity. You can easily create event handlers like this.

contextMenuItem.Click += new Telerik.Windows.RadRoutedEventHandler(contextMenuItem_Click);

where your radtreeviewitem has an x:name="contextMenuItem"

Hope this helps people who are banging their heads with this one.
