Nevron User Interface for .NET 4.0

Nevron User Interface will present you a strong docking library which provides your applications with the latest WYSIWYG docking standards and technologies.
These are interface structured hierarchies of predefined controls that can be docked, floated or redocked using visual feedback at run-time. The unique tree-based layout system allows for practically any complex structure to be achieved in a few lines of code.
The dock manager uses advanced logic for getting a valid dock area and overcomes limitations of the standard docking behavior experienced in other products. Nevron Docking Panels are extremely flexible and feature-rich.
Main features:
- Unified overall appearance integrated with the core Nevron UI Rendering System.
- Control over tabs style, tab align, caption height, buttons and font, splitter size, etc.
- Pluggable renderers. By default all the panels use the one exposed by the Dock Manager.
- Pluggable drag handlers. By default all the panels use the one exposed by the Dock Manager.
- Pluggable layout engines at any level of the tree.
- Allowed DockStyle.Fill for panel containers.
- Layout logic - absolute, relative and auto size.
- Panel permissions. Each panel has permissions specifying what functionality it exposes.
- Dock area masks - specify the allowed areas for docking per INDockAreaProvider.
- Event bubbling - each panel fires an event and delegates it to the manager (if not marked as "Handled"). This allows for flexible event handling.
- Great number of events, most of them cancelable.
