C#

OrthogonalConnector link = new OrthogonalConnector(rec1.PinPoint, rec2.PinPoint,

MeasureUnits.Pixel);

link.HeadDecorator.DecoratorShape = DecoratorShape.Filled45Arrow;

link.TailDecorator.Load(this.CreateCustomDecorator());

this.diagram1.Model.AppendChild(link);

private GraphicsPath CreateCustomDecorator()

{

GraphicsPath gpPath = new GraphicsPath();

gpPath.AddEllipse(0, 0, 10, 20);

return gpPath;

}

VB

Dim link As OrthogonalConnector = New OrthogonalConnector(rec1.PinPoint, rec2.PinPoint,

MeasureUnits.Pixel)

link.HeadDecorator.DecoratorShape = DecoratorShape.Filled45Arrow

link.TailDecorator.Load(Me.CreateCustomDecorator())

Me.diagram1.Model.AppendChild(link)

Private Function CreateCustomDecorator() As GraphicsPath

Dim gpPath As GraphicsPath = New GraphicsPath()

gpPath.AddEllipse(0, 0, 10, 20)
