The FileBrowserContentProvider is initiated using reflection internally in the RadFileExplorer control, so it is not possible to pass external parameters to the constructor. In your case I recommend you to use a Session variable in order to pass parameters to the provider. Alternatively, you could use the approach described in this KB article
. For your convenience I have attached a demo which shows how to access values entered in two TextBoxes from the code of the provider.
