when I set the diagram.AllowSelfLoops=true;Then, node connects its own anchorPoint. The result is not ideal.Please see the attached screenshot.It is normal for me to connect different Nodes.

Hi,

You can handle the Diagram.SetSelfLoopShape event and adjust the link origin and destination anchors. For example:
Code
Select All
void diagram_SetSelfLoopShape(object sender, LinkShapeEventArgs e)
{
    var link = e.Link;
    link.Shape = LinkShape.Cascading;

    link.OriginAnchor = 1;
    link.DestinationAnchor = 2;
    link.Route();

    e.Handled = true;
}


The above code produces the result in the attached image.

Regards,
Lyubo
