Overview

The WinForms Diagram is a feature-rich library for visualizing, creating, and editing interactive diagrams. It supports creating flowcharts, organizational charts, mind maps, and network diagrams either through code or a visual interface.


Flowchart

The Diagram library provides all the standard flowchart shapes as ready-made objects to build flowcharts, making it is easy to add them to a diagram surface in a single call.

Organizational chart

Built-in automatic layout algorithm specifically made for organizational charts to arrange the parent and child node positions automatically.

Nodes

Visualize any graphical object using nodes, which can be arranged and manipulated at the same time on a diagram page. They allow the following:

  • Easily create and add custom shapes.
  • Embed WinForms controls inside a node.
  • Fully customize the appearance of a node with built-in dialog boxes.

Connectors

A connector represents a relationship between two nodes. Some of the key features like connector types, bridging, and more are listed below.

Different types of connectors available in WinForms Diagram Control

Types

The WinForms Diagram provides straight, orthogonal, polyline, and curved connector types. You can choose any of these based on the type of diagram or relationship between the connected nodes.

Connector line jump behavior in WinForms Diagram Control

Bridging or line jumps

Use bridging (line jumps) to illustrate a connector’s route, making it easy to read where connectors overlap each other in a dense diagram.

Predefined arrow heads available in WinForms Diagram Control to illustrate flow direction in the diagram

Arrowheads

Use different types of predefined arrowheads to illustrate flow direction in flowchart diagrams. You can also build your own custom arrowheads.

Connector appearance customization in WinForms Diagram Control

Appearance

Like nodes, the connector look and feel can also be customized with built-in dialog boxes. The WinForms Diagram control provides a rich set of properties through which you can customize connector color, thickness, dash and dot appearance, rounded corners, and even decorators.


Ports (connection points)

Connect to specific places on a node through different types of ports or connecting points.

Multiple annotations

Add any number of labels and align them individually.

Align labels inside or outside of a node using Label feature in WinForms Diagram Control

Alignment

Labels include sophisticated alignment options: Place inside or outside a node, or at the source or target end of a connector. Automatically align when a node or connector moves.


Interactive features

Use interactive features to improve the editing experience of a diagram at runtime. Furthermore, you can easily edit a diagram with mouse, touchscreen, or keyboard interfaces.

Select and drag the nodes or connectors using handlers in WinForms Diagram Control

Select and drag

Select one or more nodes, connectors, or annotations and edit them using thumbs or handlers.

Select and resize the nodes using handlers in WinForms Diagram Control

Resize

You can resize a node in eight different directions and lock a node’s aspect ratios to keep its shape. You can also resize multiple objects at the same time.

Select and rotate the nodes using handlers in WinForms Diagram Control

Rotate

Rotate selected nodes from 0 to 360 degrees.

Undo and redo the recent changes using history manager feature in WinForms Diagram Control

Undo and redo

Don’t worry when you edit by mistake—undo and redo commands help to easily correct recent changes.

Align nodes and connectors with respect to nearest gridlines or objects using snapping feature in WinForms Diagram Control

Snap

Precisely align nodes, connectors, and annotations easily while dragging just by snapping to the nearest gridlines or objects.

Cut, Copy and Paste the select objects within diagram using clipboard feature in WinForms Diagram Control

Clipboard

Cut, copy, paste, or duplicate selected objects within and across diagrams.

Move the objects to top or bottom of the diagram using z-order feature in WinForms Diagram Control

Z-order

When multiple objects overlap, the z-order controls which object needs to be on top or at the bottom.

Combine the multiple nodes into group node using grouping feature in WinForms Diagram Control

Grouping

You can combine multiple nodes into a group and then interact with them as a single object. Nested groups are also possible with our WinForms Diagram control.


Alignment

The WinForms diagram control has predefined alignment commands that enable you to align the selected objects nodes and connectors with respect to the selection boundary.

Arrange selected objects in equal intervals using spacing commands in WinForms Diagram Control

Spacing commands

Spacing commands enables you to place the selected objects on the diagram at equal intervals from each other.

Resize selected objects to have equal sizes using sizing commands in WinForms Diagram Control

Sizing commands

Use sizing commands to equally size selected nodes with respect to the first selected object.

Align selected objects horizontally or vertically by using align commands in WinForms Diagram Control

Align commands

All the nodes or connectors in the selection list can be aligned at the left, right, or center horizontally, or aligned at the top, bottom, or middle vertically with respect to the selection boundary.


Automatic layout

Use automatic layouts to arrange nodes automatically based on a predefined layout algorithm. Features built-in hierarchical tree, radial tree, and symmetric layouts.


Rulers and measurement unit

Rulers allows you to measure the distance of nodes or connectors from the origin of the page. The size and position of objects can be specified in different units such as pixels, inches, and centimeters.

Measure the distance of the nodes from the page origin by using ruler feature in WinForms Diagram Control


Layers

A layer organizes graphical objects into a group that shares a common set of default properties, and more significantly, a z-order. You can add any number of layers to a diagram and move objects between layers.

Context menu

You can easily map frequently used commands to a context menu.

Use context menu feature to map frequently used commands


Symbol palette

Includes a gallery of stencils, reusable symbols, and nodes that can be dragged onto the surface of a diagram.

Data binding

Populate diagrams with nodes and connectors created and positioned based on data from data sources. In addition, 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. The Diagram library also supports loading data from a list or IEnumerable collection.

Exporting

You can export the diagram to different image files such as PNG, JPEG, and BMP.

Export the diagram as different image format using WinForms Diagram Control


Printing

The Diagram library supports printing with a print preview option. You can also customize the page size, orientation, and page margin, and fit diagrams to a single page.

Print the diagram from application using WinForms Diagram Control


Serialization

Our WinForms Diagram control provides support to save your diagram state in both binary and SOAP formats, and load it back later for further editing using the serializer. It also supports serialization and deserialization of diagram (.edd) files.

Flexible architecture

Our WinForms diagram control is designed to be a high-performance, easy-to-use, and easy-to-customize engine. Many of the classes and components in the library can be subclasses, so that users can extend and customize the library to meet their needs. The Diagram library, in fact, employs a model-view-controller (MVC) design to clearly separate data, presentation, and user interaction.
