Diagram

The diagram control is used for creating diagrams like flow charts, organizational charts, mind maps, floor plans, and swim lane diagrams either through code or through a visual interface that is similar to Visio.

Diagram


Nodes

Nodes are used to host graphical objects (paths or controls) that can be arranged and manipulated on a diagram page.

  • Custom shapes can also be created and added easily.
  • Appearance of a node can be fully customized.
  • Node’s UI can also be templated and re-used across multiple nodes.

Nodes


Connectors

Relationship between two nodes is represented using a connector. Multiple instances of nodes and connectors form a diagram. Some of the key features are listed below.

Connectors


Types

Types

Different types of segments are available to connect between objects.

Bridging

Bridging

Bridging is a visual indication of overlapping between two connectors.

Routing

Routing

Orthogonal connectors take a smart path that avoids overlapping with nodes to which it is connected.

Decorator

Decorator

Arrows or decorators at the edges of connectors are used to represent relationships between nodes.

Rounded Corners

Rounded Corners

Corner radius can be specified for edges in connectors.

Ports

Ports

Ports are specific points in a node to which a connector can be connected.


Label

Labels are used to annotate nodes and connectors. Diagram also make it easy to edit and align labels relative to the object to which it is mapped.

Label


Interactive Feature

Interactive features are used to improve the runtime editing experience of a diagram. You can easily edit a diagram with mouse, touch screen, or keyboard interfaces.

Rotate

Select, Drag, Resize, Rotate

Objects can be selected and then dragged, resized, or rotated.

Snap

Snap

Objects can be aligned easily against gridlines or neighboring objects.

Keyboard Interactions

Keyboard Interactions

All common actions can also be performed through keyboard input.

Connect

Connect

The connect tool can be used to create a connection between two nodes, ports, or points.

Edit Connector

Edit Connector

Connector’s route can be manually edited by dragging thumbs that are visible after selection.

Zoom Pan

Zoom Pan

Large diagrams can be explored using the zoom and pan tool.

Group

Group

Multiple nodes or connectors can be grouped together to form a single object called a group.

Drawing Tool

Drawing Tool

Drawing tool enables users to draw custom nodes and shapes by clicking and dragging on the diagram surface.


Data Binding

Data binding is used to populate diagrams with nodes and connectors created and positioned based on data from external data sources. Data in any format can be easily converted, mapped, and consumed in the diagram by setting a few properties, without having to write any code. Diagram also supports loading data from an ObservableCollection, List, or IEnumerable collection.

Data Binding


Commands

Diagram control has a predefined set of commands. Some standard commands are mapped to keyboard shortcuts. It is also possible to configure new commands and key combinations.

Commands


Automatic Layout

Automatic layout is used to arrange nodes automatically based on a predefined layout logic. There is built-in support for organization chart layout, hierarchical tree layout, and radial tree layout.


Overview

Overview control is used to improve the navigation experience when exploring large diagrams. It displays a small preview and allows performing operations such as zooming and panning within it.

Overview


Symbol Palette

The symbol palette is a gallery of reusable symbols/nodes that can be dragged and dropped onto the surface of the diagram.

Symbol Palette


Performance

It is possible to work with very large numbers of nodes since the diagram uses UI-virtualization techniques to selectively load only the objects that lie within the viewport area. Smooth scrolling performance is achieved using an inbuilt spatial search algorithm that builds an index based on a node’s position.

Performance


Serialization

Diagram’s state can be persisted to XML format and then be loaded back using serialization.

Serialization


Rulers and Measurement Unit

Rulers are used to measure the distance of nodes and connectors from the origin of the page. The size and position of objects can also be specified in different units like pixels, inches, and centimeters.

Rulers and Measurement unit


Exporting and Printing

Diagrams can be easily exported as image files (.png, .jpeg, .bmp, and other formats) and can also be printed as documents.

Exporting and Printing


Miscellaneous

There are several other features available to enhance the diagramming experience.

Gridlines

Gridlines

Gridlines provide guidance when trying to align objects.

Page Layout

Page Layout

The drawing surface can be given a page-like appearance using page size, orientation, and margins.

User Handles

User Handles

Frequently used commands can be easily mapped to the user handle.

Context Menu

Context Menu

Frequently used commands can be easily mapped to the context menu.


Diagram Builder

Diagram builder is a diagraming application created using the diagram control. It is used to create, edit, save, export, and print diagrams. It has a symbol palette, property editor, overview window, toolbox, and menu to provide a great editing experience.
