RadEditor - code for the Document and Image managers

The Telerik RadEditor becomes far more powerful once you wire up the Document and Image Managers to real, user-specific folders. Out of the box, the editor doesn’t know where your application stores files, how your users’ directories are structured, or which paths they’re allowed to browse. That’s why a clean, predictable initialization routine matters. In this article, we walk through the exact VB.NET code needed to configure the RadEditor so each user sees only their own images and documents — with proper view paths, upload paths, delete paths, and file filters. It’s a simple pattern, but once you have it in place, the RadEditor behaves consistently and securely across your entire application.
