Please, accept my apologies for not being clear enough in my previous reply.
By saying "Does the property function properly if you are using the built-in FileExplorer's provider?
" I wanted to know what is the FileExplorer's behavior when the DisplayUpFolderItem
property is configured, but your custom content provider is not assigned. In this way you will know what is the FileExplorer's behavior with its built-in content provider, and so whether your custom one is changing this functionality.
Additionally, I have tested the control with with the used by you version in IE10, but still was not able to reproduce the problematic behavior on my side. I will need to reproduce the issue on my side and the examine the exact configuration that is causing it in order to provide any further assistance on the matter, so my request about a simplified fully runnable project still applies.
