Associate Custom Data with Items

You can associate custom values from any data type with diagram elements by setting their Tag and Id properties. If the associated data is of a value type or of type that is serializable (marked as [Serializable] and implementing the ISerializable interface), then it is saved and loaded together with the diagram items when a diagram is saved or loaded. The FindNode, FindLink, FindNodeById and FindLinkById methods let you find diagram elements associated with a specific value.

Inspecting Items Geometry

• The Intersects method of DiagramLink lets you test if links intersect other links or nodes.
• The Length method of the DiagramLink class returns the total length of a link.
• The ContainsPoint method let you check if an item contains specified point.

Fluent API

Extension methods in MindFusion.Diagramming.Wpf.Fluent and MindFusion.Diagramming.Wpf.Layout.Fluent namespaces let you initialize objects using fluent programming style:

C#

using MindFusion.Diagramming.Wpf.Fluent;
using MindFusion.Diagramming.Wpf.Layout.Fluent;
//...

diagram.Factory
    .CreateShapeNode(20, 20, 60, 40)
        .Brush(Colors.LightGray)
        .Font("Arial", 12)
        .EnableStyledText(true)
        .Text("Task <i>1</i>")
        .ToolTip("This is the task")
        .TextRotationAngle(15);

new TreeLayout()
   .LevelDistance(20)
   .NodeDistance(20)
   .LinkStyle(TreeLayoutLinkType.Cascading3)
   .Arrange(diagram);
