A complete docking tool window and multiple document interface solution.
Actipro Docking & MDI for WinForms offers sophisticated docking controls that mimic Visual Studio’s interface, allowing developers to create flexible and interactive applications. It supports drag-and-drop docking, floating, auto-hide modes, and both standard and tabbed multiple document interfaces. The product provides extensive customization, layout persistence, and runtime configuration options tailored for professional desktop applications.

Docking Tool Windows

Enables docking of tool windows on any side of a host container with support for nested hierarchies, resizing, tabbed containers, and floating forms to organize application UI dynamically.

Multiple Document Interface Support

Includes both standard MDI with tiling and cascading, and tabbed MDI modes where document tabs can be dragged to create multiple tab groups, enhancing workspace management.

Auto-hide and Inner-fill Modes

Tool windows can collapse into auto-hide mode to conserve screen space, or fill the client area without documents using inner-fill mode for varied layout needs.

Layout Persistence and Serialization

Supports saving and loading of tool window and document layouts to XML files or streams, allowing restoration of complex UI states across sessions or application modes.

User Interaction Features

Provides docking guides, drag/drop reordering, snapping with magnetism, tab overflow handling, and configurable close/options buttons for intuitive window management.

Designer and Runtime Support

Includes full design-time support to visually arrange docking layouts and serialize them into code for seamless runtime application initialization.

Rendering and Theming

Offers built-in rendering styles like Metro, Visual Studio, Office, and Windows Classic, with an extensible interface to create custom visual themes and integrate with host applications.

Document Management Enhancements

Document windows reflect modification states, support closing cancellation, provide Ctrl+Tab navigation, and can float as independent windows, enriching document handling capabilities.
