AddFlow for Silverlight is a Silverlight 4 control for creating flowchart diagrams. AddFlow for Silverlight offers the following advantages:

• A small deployment assembly: The size of the Lassalle.Silverlight.Flow.dll file is less than 150 Kb.
• A light programming interface, great flexibility and full integration with the Silverlight environment
• Separation between visual appearance (defined in xaml) and logic: Every visual elements can be customized: nodes, links, connectors, resizing handles, etc...
• Runtime royalty free

AddFlow for Silverlight Professional Edition also include a set of graph layout components

AddFlow for Silverlight Main Features

General

• Drawings can be made interactively or programmatically.
• Distinct shapes, styles, colors, font can be defined on a per item basis (for a node or a link) or as default properties for the control.
• Use of the LINQ technology allowing you to traverse the graph in many ways.
• Many properties allowing customizing the control (CanDrawNode, CanMoveNode, CanMultiLink, etc...) or an item (IsXSizeable, IsYSizeable, IsXMoveable, IsYMoveable, IsSelectable, IsStretchable, etc...)
• A node is a ContentControl: it may contain anything.

Interactivity and display facilities

• Multi selection
• Multi-level Undo/Redo
• Nodes stay connected when moved or resized
• Zooming
• Scrolling
• Alignment to grid

Nodes

• A node may contain anything and any other Silverlight control
• The node content is fully customizable (styles, templates)
• 43 Predefined shapes (and the list can be easily increased)
• Ability to display a text and an image in a node
• Text positioning options
• Image positioning options
• Shadows, transparency, zorder, etc...

Links

• 15 predefined arrow styles (and the list can be easily increased: it is easy to define your own custom arrows)
• The style of a link can be redefined.
• Stretchable links. A link can be composed of many segments. The user can interactively add or remove segments
• Curved links (Bezier and Spline)
• Reflexive links
• Possibility to interactively change the origin node or the destination node of a link

Automatic Graph Layout (Professional version only)

AddFlow provides a set of several graph layout algorithms:

• Hierarchic layout
• Orthogonal layout
• Symmetric (force-directed) layout
• Series Parallel layout
• Tree layout
• Radial Layout

Each of these graph layout algorithms performs a layout on a graph. Performing a layout automatically positions its nodes (also called vertices) and links (also called edges).
