What's new in WpfDiagram V3.01?

• Preserve Order in Tree Layouts - A TreeLayout can keep the original geometric order of child nodes when arranging them under their parent. This can be used to arrange tree branches in a specific order by first positioning them in increasing horizontal or vertical positions.
• Selection Improvements - Set Behavior to SelectOnly to let users select existing items, but not modify them or draw new ones. 

What's new in WpfDiagram V3.0?

• Visual Studio 2012 support.
• Themes and theme editor.
• Node effects.
• Multi-page diagrams and tabbed views.
• Multiple labels per link.
• Layers and layer list-view control.
• One-way graph layout.
• Parallelization of layout algorithms.
• Magnifier tool.

What's new in WpfDiagram V2.8.2?

• Rotate attached nodes
• SaveToXml method saves the definition of custom Shapes
• If NegatedY is set, the vertical Ruler scale displays negated Y coordinates
• In-place TextBox control wraps text to multiple lines by default
• Diagram control automatically added to the Visual Studio toolbox by the installer

What's new in WpfDiagram V2.8?

• Virtualize diagram items
• Id property added to DiagramItem
• FindLinkById and FindNodeById methods
• Lane headers can be anchored to the top-left of the viewport
• Improved path-finding for long links in QuickRouter
• StartPoint and EndPoint properties added to DiagramLink

What's new in WpfDiagram V2.7?

• Automatic node alignment - If AutoAlignNodes is enabled, the node currently being drawn or resized is aligned to another node so that a pair of their vertical or horizontal sides become collinear. To specify the maximal distance at which nodes are aligned, set the AutoAlignDistance property. The pair of aligned nodes is indicated visually by drawing an alignment guide using the pen assigned to AlignmentGuidePen.
• Fractal tree layout - FractalLayout is a tree layout algorithm that places child nodes symmetrically around their parent node. Nodes at the lowest level are arranged directly in a circle around their parent. At the upper level, the already arranged nodes form branches that are arranged in a circle around the new parent node. The algorithm is recursively repeated till the highest level is reached. If nodes in the tree have a uniform number of children, the end result has a fractal-like appearance (subsets of the graph look like scaled-down copies of the whole graph). You can choose which node should be displayed at the center of the topmost circle by setting the Root property. If it is not specified, the algorithm automatically selects a root that leads to more balanced distribution of nodes.
• Miscellaneous
• Specify start and end nodes in LayeredLayout via the StartNode and EndNode properties.
• GetAllIncomingLinks and GetAllOutgoingLinks methods added to DiagramNode.
• Self-loop links that connect TableNode rows or TreeViewNode items are now routed around the node preserving their correct end points.
• Links automatically align to the center of table rows or tree-view items when AutoSnapLinks is enabled.
• Diagram.Viewport returns the currently visible region of the diagram.
• Draw with the right or middle mouse button by setting RightButtonAction or MiddleButtonAction to Draw.

What's new in WpfDiagram V2.5?

Swimlane layout
SwimlaneLayout can be used to arrange process diagrams in which nodes representing activities are placed in swimlanes representing resources. By default, the algorithm works with the diagram's LaneGrid, but its SwimlaneGrid property can be set to any class that implements ISwimlaneGrid. This allows applying the layout to a custom-drawn grid rendered through a custom control template, or one composed of locked background nodes.

CascadeLayout algorithm
CascadeLayout places nodes on a virtual grid and arranges links orthogonally, such that if the source graph is planar all links are guaranteed to have no more than two bends and will not intersect. By default the layout method arranges nodes in rows and link segments in columns; this can be changed by setting the Orientation property.

TriangularLayout algorithm
TriangularLayout places nodes on a virtual grid, such that if the source graph is planar, all links are guaranteed to have a single segment and not intersect. If the graph is not planar, its intersecting links can be optionally segmented and bended in order to improve readability. The layout method places the nodes from the external face on a triangle and recursively adds the rest of the nodes as vertices of internal triangles. As a result, it is very effective for near maximal-planar (a.k.a. triangular) graphs.

HierarchicalLayout algorithm
HierarchicalLayout places nodes on user-defined levels, such that if the source graph is level-planar, all links are guaranteed to have a single segment and not intersect. The layout method requires that for each node LayoutTraits contains a HierarchicalLayoutTraits.Level entry specifying the level, and no two connected nodes must be on the same level.

Miscellaneous

• OrthogonalLayout results have been greatly improved for nonplanar and high vertex-degree graphs.
• LinkType adds supports for Bezier links to SpringLayout.
• The swimlane grid can be printed by setting the EnableLanes property of PrintOptions.
• The text of lane headers can be edited by the user if LaneGrid.AllowInplaceEdit is enabled.
• TextBrush has been moved to the base DiagramItem class and now it is a dependency property.
• EnumAllCycles method added to PathFinder.
• Table cells now derive their default text attributes from the CellTextStyle property.

What's new in WpfDiagram V2.4?

Templated Nodes
The TemplatedNode class represents nodes whose appearance is set through Xaml data templates. This class is useful mostly as a base type of custom nodes. However it is not abstract and can be used directly if the text -related properties defined in DiagramItem are sufficient for your purposes. The appearance of such nodes can be set through their Template property or the NodeTemplate property of the Diagram class.

WmfExporter component
The WmfExporter class creates a Windows Metafile (WMF) drawing from the content of a Diagram. The exporter enumerates all graphics primitives contained in the WPF visual tree and creates corresponding WMF records. This enables custom graphics and hosted controls to be rendered in WMF too.

What's new in WpfDiagram V2.3.3?

Export to SVG
The SvgExporter class creates a Scalable Vector Graphics (SVG) drawing from the content of a Diagram. The exporter enumerates all graphics primitives contained in the WPF visual tree and creates corresponding SVG elements. This enables custom graphics are hosted controls to be rendered in SVG too.

Other improvements in WpfDiagram V2.3.3:

• If LayoutTraits[SpringLayoutTraits.Frozen] is set, SpringLayout ignores forces acting on a node but still consider the node's repulsion force on other nodes
• The SerializeControl and DeserializeControl events let you save information for controls hosted in DiagramNodeAdapter objects
• The AnimatedLayout sample project demonstrates how to use SpringLayout for animation and partial layout

What's new in WpfDiagram V2.3.2?

Support for .NET 4
The package now includes a .NET 4 version of the MindFusion.Diagramming assemblies, available in the VS2010 subfolder of the installation folder. These assemblies can also be used in applications that target the .NET 4 Client Profile. The VS2010 folder also includes sample projects for Visual Studio 2010. Version 3 of the .NET runtime is still supported.

Styling
This version enables styling of diagram items through the WPF styling system. Now DiagramItem provides a Style property, which can be set to an instance of the System.Windows.Style class. The style can contain setters for the Brush, Stroke*, Text* and Font* dependency properties that were introduced in the last release. Using the style's TargetType attribute it is also possible to define a global style in the window or application resource dictionaries for each type of node.

Other Improvements:

• ContainerNode now provides an UpdateBounds overload that also includes links in the new node boundaries.
• A new ZoomToRect overload can center the specified rectangle in the current viewport.
