Hi Telerik Staff,
I just copy the codes using C# and it doesn't compile. And I copied it on your help website : http://www.telerik.com/help/wpf/radtreeview-how-to-bind-to-self-referencing-data.html.
Please send me a project on this. I hope you will send a zip file for me.
Thanks,
Mac

Hello macky,
I see that you've opened a forum thread for RadTreeView for Silverlight but you have pasted a link from WPF documentation. Here is the SL`s documentation link. I can thought of at least one difference in the code snippets ( HierarchicalDatatemplate in WPF ==> telerik:HierarchicalDataTemplate in SL). Let us know if this helps you.s

Hi Vincent,
Probably because your converter class has not been build successfully, have you added System.Linq namespace necessary for the "Where" extension methods? I am attaching a working example created by following the help article. Let us know if this helped you.

HI! Thank you! I know now the correct code...
But I have some concern.. in your textblock, when I select an item from the treeview, it binds the value. Do you know how to bind the ITEM ID and the Parent ID when I select an item in the treeview?

Hi Petar. How do I update the Text as well as the Parent ID when I add/remove/edit an item through a RadContextMenu?

Hi Angeli,
You first have to access the RadTreeViewItem clicked with the mouse right button when the ContextMenuOpens:
You can see this realized in this demo. Then you probably need a twoway binding to a ViewModel ( if you want the visual changes to reflect the data behind). Let us know if you need further assistance on this.
Kind regards,
