How to Create Custom Shapes with Custom Connection Points for DiagramDesignerControl

This example illustrates how to create custom shapes and add them to the DiagramDesignerControl.

Show Me

A complete sample project is available in the DevExpress Code Examples database at http://www.devexpress.com/example=T320892.

The Diagram control supports a special language for defining shapes. The main element that contains shape description is ShapeTemplate. This element describes a shape contour and may contain several segments:
- Start. Specifies the start point
- Line. Defines a line with start and end points
- Arc. Defines an arc with start and end points

To specify connection points, use the ShapeTemplate.ConnectionPoints property.
To register custom shapes, create a stencil with the DiagramStencil.Create method and pass it to the DiagramToolboxRegistrator.RegisterStencil method.
