Yeah I dont know why it didnt capture that in the screen shot, but basically I am creating the link from anchor 3 to anchor 2 like in the picture.

But in real life in my system, there is a little red circle with a diagonal red line (i.e.: now allowed icon or something like that) the moment I hover over anchor point 2, or any other anchor for that matter.

When I release the mouse the link is not created.

This still happens in the winapp2_debug application.

With lack of better means, I took a picture with my phone.



This was running the winapp2-debug application.

UPDATE:

The versions of the assemblies I am using:

MindFusion.Common 1.2.3951.40403
MindFusion.Diagramming 5.5.0.24531
MindFusion.Diagramming.WinForms 5.5.0.24532

This is expected if the mouse pointer is outside the node, and I suppose it is a couple of pixels above it on this screenshot. If you enable the link's AutoSnap property, it will automatically connect to nearby nodes even if the pointer is not over a node. However the control explicitly excludes the link's origin from the search then, so the pointer must still be inside the origin node to draw a reflexive link.

Aaaahhhh.. well yes, you are correct. That clears things up.

After moving carefully to find the anchor point I got it working.

Is there a way to show the anchor points of the destination node (even if its the same as the origin) when the mouse hovers over it?

It would be very useful so that users are not looking for that anchor point which is just 2 pixels away.

Regarding your suggestion, were is the AutoSnap property? I do not see it on the DiagramLink or Diagram.

UPDATE:

Never mind, I my actual application it works like that. I dont remember how I set it but its already done, so forget it.

Thanks for your help.

Sorry, I was thinking of the AutoSnapLinks and AutoSnapDistance properties we have in the Silverlight and WPF controls, but haven't implemented yet for Windows Forms. We can add them for the next release if that's what you need - connecting a link to the nearest node even if the mouse pointer is outside of the node.
