Hi Arthur,

You would need to take the Styles for the various file system types (i.e. DirectoryData, DriveData, MyComputerData) and create copies that target TreeViewItem instead of BreadcrumbItem. TreeViewItem doesn't have an ImageSource property though, so there you'd need to:

1. Bind Header to the current DataContext (i.e. <Setter Property="Header" Value="{Binding}" />
2. Set HeaderTemplate to a DataTemplate that uses includes Image and TextBlock controls (with the appropriate bindings).

Finally, you'd have to duplicate the TreeView sync code from the Breadcrumb Demo. If you get stuck, please send over a small sample project that shows the issue to our support address. That will help us narrow down any issues.

I guess im not the only one searching for this.

Ok, after adding the styles it worked.
I only had to adjust the mycomputerdata to an observablecollection for the treeview


  Dim MyFileInfo As MyComputerData

  MyFileInfo = New MyComputerData

  FileTreeView.ItemsSource = New ObservableCollection(Of MyComputerData)(New MyComputerData() {MyFileInfo})

and I adjusted the drivedata getdirectories property so that only when a drive is ready that it will be loaded. Otherwise this function will raise an event that the drive is not ready and i hate raised events when everything supposed to be ok....


            Dim DInfo As DriveInfo = Me.Info
            If DInfo.IsReady Then 'drive found?
              Dim directoryInfos() As DirectoryInfo = DInfo.RootDirectory.GetDirectories()
              For Each directoryInfo As DirectoryInfo In directoryInfos
                Me._directories.Add(New DirectoryData(directoryInfo))
              Next directoryInfo
            End If

The latest build of this product (v24.1.1) was released 2 months ago, which was after the last post in this thread.
