Can I create and new ports to a Symbol at runtime?

Essential® Diagram allows you to create new ports and add them to a symbol at runtime. Creating a new port is simply a matter of instantiating the required port, adding it to your symbol's Symbol.Ports collection, and specifying the port location. The following code should give you an idea:

The Diagram.Windows\Samples\Symbol Design\PortsAhoy sample that ships with the product demonstrates how to create and add new ports to a symbol.

C#

Symbol mysymbol; // Symbol reference
// Center the port on the symbol
PointF pt = new PointF(mysymbol.X + mysymbol.Width / 2, mysymbol.Y + mysymbol.Height / 2);
CirclePort port = new CirclePort(pt);
mysymbol.Ports.Add(port);
port.Location = pt;

VB

Private mysymbol As Symbol ' Symbol reference
' Center the port on the symbol
Private pt As PointF = New PointF(mysymbol.X + mysymbol.Width / 2, mysymbol.Y + mysymbol.Height / 2)
Private port As CirclePort = New CirclePort(pt)
mysymbol.Ports.Add(port)
Private port.Location = pt
