GoDiagram for WinForms
Advanced Controls for .NET Diagrams Packed with Diagramming Concepts
GoDiagram makes it easy to build applications where users can see and manipulate graphs of nodes connected by links.
From simple diagrams to interactive workflows and complex system monitors, GoDiagram helps you quickly create rich displays for your diagramming needs.
Built-in and Customizable
GoDiagram contains several built-in node types and full sample applications to get your project started quickly. GoDiagram is built from the ground up in C# and is designed to be extensible for your custom needs.
Concepts and Features
The GoDiagram library, Northwoods.Go, is a set of controls and classes built on the .NET platform. GoDiagram makes it easy to deliver editors that allow users to see and manipulate diagrams of two-dimensional graphical objects arranged in a scrollable window.
GoDiagram provides a variety of basic graphical objects such as rectangles, ellipses, polygons, text, images, and lines. You can group objects together to form more complex objects. You can customize their appearances and behaviors by setting properties and overriding methods.

A True .NET component
GoDiagram is written entirely in C#. It only depends on the standard .NET Framework classes and does not explicitly call any external functions.
Sample Program
Here is the full VB.NET source code to MinimalApp. The screenshot shows how the MinimalApp appears after selecting the two initial nodes, drag-copying them, moving them, creating links between some of them, and then renaming a blue one to “blue” and a magenta one to “magenta”.
GoDiagram View
A GoDiagram view is a control that displays a GoDiagram document. It supports mouse-based object manipulation, including selecting, resizing, moving and copying using drag-and-drop. GoDiagram organizes input behaviors into tools that you can modify, override, or add or remove from a view. The view also supports in-place editing, printing, and grids.
GoDiagram Document
A GoDiagram document implements a model that supports manipulation of objects. Adding an object to the document makes it visible in the document's views. You can organize objects in layers. GoDiagram provides support for composing and manipulating graphs (node & arc diagrams), where nodes have ports that are connected by links.
Flexibility and Extensibility
The GoDiagram library is flexible and extensible. Predefined node classes make it easy to build many kinds of graphs. You can easily customize most objects for application-specific purposes by setting properties or by subclassing. You can add completely new graphical objects to the existing framework.
AutoLayout
To provide greater customizability and ease of use, Northwoods offers, as a separate option, another library, Northwoods.Go.Layout. This option extends GoDiagram by providing sophisticated automatic layout algorithms for nodes in graphs. The AutoLayout component is sold and documented separately.
Diagram Components for .NET Winforms
GoDiagram provides diagramming components for .NET Winforms, and has been designed to take advantage of the many new features that Microsoft .NET provides. As a member of the Visual Studio Partner (VSP) Program, we work closely with Microsoft to ensure that our .NET products integrate seamlessly into Visual Studio.
For web development consider our newer product, GoJS for HTML5 Canvas. GoDiagram for WebForms is still available for existing customers.
Unmatched Customer Service
In addition to providing sample and comprehensive guides for GoDiagram .NET Windows, we also provide documentation and developer-to-developer support from the engineers who built the GoDiagram library. We offer a free evaluation of the full library with no time limit, although unlicensed libraries come with a watermark.
Source code for GoDiagram is available. Technical support and library updates for 1 year are included in most purchases.
Northwoods Software has been building graphical frameworks for 20 years, with customers that include a quarter of the Fortune 100 and innovative companies worldwide.
