I am having trouble getting my line ends and arrows to look right. I attached 2 pictures to show. The first one shows how the arrow going into the second node doesn't come in from the side like I want.

The second image shows how the link start and end both start out vertical when they should be horizontal.

A note I do have the diagram.RouteOptions.StartOrientation and EndOrientation set to Horizontal.

What else can I change to make it work?

Thank you for the reply.

I am calling the Route() method whenever a link is created or a node is moved. What you see in the images is the result.

There are no large nodes in the background that I know of and I have not done anything with LinkRouter. Is LinkRouter a good place to affect how things are arranged?

What kinds of settings affect how the routing is done? Specifically I need to know how to make the arrows be horizontal when they are close to the side of a node like you see in the images.

For some reason I am not getting the notification email when you guys post replies to this thread so I just saw this post.

Calling Route doesn't help and nothing else is being done after that so I am still stuck.

One thing interesting is if the destination node is below the source node you get the weird routing as in the image. If, on the other hand, the destination node is above the source node the routing always comes in horizontal and everything is fine.

Does that give any clues about what is happening?

The Mind Fusion guys are WONDERFUL to work with. I ended up sending my project to them and they found a small issue in the grid router that they will fix in the next release, but also gave a solution that works right now.

Basically I already had a method in my project in a file I called LinkConfig that returns the AnchorPattern for a node. They had me change it to define the link orientation when creating the anchor points. This works good and solves the issue I am seeing. Here is the code:

        public AnchorPattern GetAnchorPattern()
        {
            AnchorPattern anchorPattern = new AnchorPattern();

            foreach (AnchorEntry entry in anchorEntries)
            {
				var ap = new AnchorPoint(entry.X, entry.Y, entry.AllowIncoming, entry.AllowOutgoing);
				if (entry.X == 0 || entry.X == 100)
					ap.LinkOrientation = Orientation.Horizontal;
				if (entry.Y == 0 || entry.Y == 100)
					ap.LinkOrientation = Orientation.Vertical;
				anchorPattern.Points.Add(ap);
            }

            return anchorPattern;
        }
 

This works because my nodes are all 100 x 100 in size and the anchor points are arranged around the outside of the nodes, so if X is 0 or 100 we know the anchor point orientation should be horizontal and if Y is 0 or 100 we know the orientation should be vertical.

Very nice solution. I didn't even know anchor points could have an orientation, so this is good learning too.
