You can implement your own breadcrumb navigation by handling the FileExplorer's OnClientFolderChange
event and get the path and the name of the currently opened folder in it. Once you assign the collected data to links forming your breadcrumb navigation, you can handle their click event and open the desired folder by using the FileExplorer's open()
You can also see a possible way to integrate breadcrumb with RadTreeView in the following forum thread: http://www.telerik.com/forums/breadcrumb-with-treeview
