Programmatically adding XsltListViewWebPart inside panel not showing folder contents.

Hi there,

I am adding couple of document libraries as XsltListViewWebparts inside a panel, the webparts are showing the items fine until I create a new folder. The WebParts are showing the folder but when I click the folder, it does not show me any contents. I tried to set folder content type id to "folderCtId" and "rootFolder" fields as many forums are suggesting but those are all not exposed as properties/fields in SharePoint 2010. I tried to set "FolderCTIDParameter" and "RootFolderParameter" fields with no luck as  both are const fields. Any help would be greatly appreciated.

Thanks
