    Hi Travis,

     

    Thank you for your post. I have been looking into your issue and it occurs because the XamDataTree control and the NodeLayout control do not have the same DataContext. This is why your binding does not work. My suggestion is to use Source for your binding like e.g.:

     

    <Button  Command="{Binding  Source={StaticResource vm}, Path=ShowReportCommand}">

     

    I am attaching a sample application(DataTree_Button_MVVM.zip) that shows this approach.

     

    Let me know, if you need any further assistance on this matter.
