I created a class that inherits from FileManagerDialogConfiguration (and ImageManagerDialogConfiguration), which loads the correct configuration for my website (I have written a custom FileSystemBrowser, which takes some substantial configuration). This greatly reduces the amount of repeated code for loading FileExplorer and RadEditor. However, I can't set the RadEditor ImageManager (or FileManager.Configutation) property because it is Read Only. Is there a reason it is read only? Is there any work around for this?
