Bind SharePoint Document Library docs and folders in Silverlight TreeView Control

Question

Hi,

I want to Bind the SharePoint Document library docs and folders in Silverlight TreeView control using Silverlight Client Object Model.

I did it but i couldnt make it recursive so that all the Folders/Subfolders/SubFolders binds into the TreeView control because of the asynchronous call. only the last item binds with the child.

Please give me a suggestions how can i do this?

PS: I am using SharePoint 2010 and Silverlight 4

Thanks and Regards

Harsh
