Information-Rich Diagrams

Build elegant diagrams and org charts

The DevExpress Diagram control allows you to incorporate advanced and fully customizable diagrams within any WinForms software project. Our WinForms Diagram component allows users to draw org charts, flowcharts, and diagrams from scratch, load visualizations from an XML file, or generate visual relationships from a data source.

DevExpress Diagram includes a fully integrated Visual Studio Diagram Designer. With it, you can construct diagrams at design time and allow users to modify diagrams within your WinForms app at runtime. Visual Studio Smart tags help you easily add a Ribbon UI, a Toolbox, and our Pan/Zoom/Property Panels to your WinForms app.

Our WinForms Diagram control includes over 130 built-in shapes, images, containers, connectors, and lists. You can also import SVG graphics and use them as a basis for custom shapes. All shapes support parameterization, so you can customize shape paths as needed. Default shapes include:

• Basic Shapes
• FlowChart Shapes
• SDL Diagram Shapes
• Decorative and Arrow Shapes
• Software Icons

Run Chart Demo To execute this demo, you must first install the DevExpress WinForms product library .

Transform Data into High-Impact Visualizations

Build diagrams from your data sources with ease

The DevExpress Diagram control can transform a data source into interactive and customizable diagrams. Our integrated WinForms Item Template Designer allows you to design templates for diagram items and connectors. Our feature-rich API has been designed to empower you and your team. With this API, you can easily generate org charts, flowcharts, and advanced diagrams programmatically.

Video Overview

Easy-to-Use Runtime Designer

Power to the user

Our WinForms Diagram Control includes both a Visual Studio Diagram Designer and a powerhouse runtime Designer. With these designers, you are free to create/modify diagrams within Visual Studio or allow users to create/modify diagrams at runtime.

The DevExpress Diagram Designer replicates many features/capabilities found in Microsoft Visio. You can draw a diagram manually or import an existing diagram from a file. You can apply predefined themes or create a custom theme as needed. And yes, you can also change shape styles, specify page orientation and size. Our Diagram Designer includes dozens of options/tools to view, manipulate, and edit diagrams.

• Text Editing
• Undo/Redo and Clipboard Operations
• Select / Transform Shapes
• Rulers and Dynamic Grid
• Snap to Grid/Items
• Show/Hide Subordinate Shapes
• Pan / Zoom / Scroll

WinForms Themes and Application Skins

Over 50 Custom Themes Designed to Amaze

You can specify a theme when you ship your app or allow end-user to modify the look and feel of your WinForms application on the fly. And yes, you can even customize our pre-built application skins/themes with the free DevExpress WinForms Skin‑Theme Editor. The following are a few of the skins/themes included in our distribution.

Basic Vector

Pine Light Palette

Office 2019 Colorful

Default Palette

WXI

Calmness Palette

Office 2019 Black

Forest Palette

Customizable Appearance

Deliver perfect user experiences

The DevExpress WinForms Diagram control ships with predefined themes, shape styles, DevExpress Skin/Theme support, and a custom draw API to help you address a variety of usage scenarios and deliver fully customizable data visualizations for your enterprise.

Auto Layout

Arrange diagram shapes instantly

Our WinForms Diagram control includes automated tools designed to quickly construct well-organized diagrams. Predefined drawing options (auto layout styles) ensure that all shapes within a diagram are arranged, aligned, and spaced in the best possible manner.

Automatic layout styles include:

• Tree Graph
• Layered (Sugiyama) Graph
• Circular Layout
• Tip-Over Tree Layout
• Mind-Map Tree Layout
• Org Chart Layout

And yes, you can also use our comprehensive API and apply a custom algorithm when necessary.

Connectors & Routing

Shape it and route it automatically

Our WinForms Diagram Connector tool helps you connect any two shapes or points directly on its canvas. You can customize line color, weight, and style, control the look of end points and arrows. You can curve or angle connectors as needed and can manage connection points in a variety of ways. You can also add, edit, or delete text for your connector.

When you use our automatic connector routing option, you don't have to manually rearrange connectors and shapes. The connector will route itself around shapes that are in the way and it will find the best point on which to connect to a shape.

Print. Export

From a screen to the printed page

Turn your diagram into a printed report/file with a simple method call or use our WinForms Diagram control’s Print Dialog. Use built-in dialogs to customize page margins, document orientation, paper size, and relevant page settings. Diagrams can be exported to PDF, SVG, and other common image formats including PNG, JPEG, BMP, and GIF.
