Hi,

When I create links for my diagram I set both link.OriginAnchor and link.DestinationAnchor. These "seem" to work for the most part, but not always. Is there some action that I could be taking subsequent to making these settings that would cause them to be ignored?

If you look at the attached screenshot, you'll see that the the link coming out of the bottom of Task 1 is correct.
The link coming out of the right of Task 5 should also be coming out of the bottom of that task.

Any thoughts?

Thanks in advance.

Hi,

First off, we've renewed our license.

I'm still having issues with the anchors I'm setting not being used.
I have set swimLayout.Anchoring = Anchoring.Keep; as well as
diagram.RoutingOptions.Anchoring = Anchoring.Keep;

I'm setting the preferred anchor points for the source and target nodes as follows.
The returned value from this function is assigned to:
link.OriginAnchor or link.DestinationAnchor.

    protected int getTaskAnchor(ShapeNode node, string side)
    {
        if (side == "left")
        {
            if (!node.AnchorPattern.Points[2].AllowIncoming)
            {
                node.AnchorPattern.Points[2].AllowIncoming = true;
                return 2;
            }
            if (!node.AnchorPattern.Points[1].AllowIncoming)
            {
                node.AnchorPattern.Points[1].AllowIncoming = true;
                return 1;
            }
            if (!node.AnchorPattern.Points[3].AllowIncoming)
            {
                node.AnchorPattern.Points[3].AllowIncoming = true;
                return 3;
            }
            if (!node.AnchorPattern.Points[0].AllowIncoming)
            {
                node.AnchorPattern.Points[0].AllowIncoming = true;
                return 0;
            }
            if (!node.AnchorPattern.Points[4].AllowIncoming)
            {
                node.AnchorPattern.Points[4].AllowIncoming = true;
                return 4;
            }
        }
        if (side == "right")
        {
            if (!node.AnchorPattern.Points[7].AllowOutgoing)
            {
                node.AnchorPattern.Points[7].AllowOutgoing = true;
                return 7;
            }
            if (!node.AnchorPattern.Points[6].AllowOutgoing)
            {
                node.AnchorPattern.Points[6].AllowOutgoing = true;
                return 6;
            }
            if (!node.AnchorPattern.Points[8].AllowOutgoing)
            {
                node.AnchorPattern.Points[8].AllowOutgoing = true;
                return 8;
            }
            if (!node.AnchorPattern.Points[5].AllowOutgoing)
            {
                node.AnchorPattern.Points[5].AllowOutgoing = true;
                return 5;
            }
            if (!node.AnchorPattern.Points[9].AllowOutgoing)
            {
                node.AnchorPattern.Points[9].AllowOutgoing = true;
                return 9;
            }
        }
        if (side == "bottom")
        {
            if (!node.AnchorPattern.Points[12].AllowIncoming)
            {
                node.AnchorPattern.Points[12].AllowIncoming = true;
                node.AnchorPattern.Points[12].AllowOutgoing = true;
                return 12;
            }
            if (!node.AnchorPattern.Points[11].AllowIncoming)
            {
                node.AnchorPattern.Points[11].AllowIncoming = true;
                node.AnchorPattern.Points[11].AllowOutgoing = true;
                return 11;
            }
            if (!node.AnchorPattern.Points[13].AllowIncoming)
            {
                node.AnchorPattern.Points[13].AllowIncoming = true;
                node.AnchorPattern.Points[13].AllowOutgoing = true;
                return 13;
            }
            if (!node.AnchorPattern.Points[10].AllowIncoming)
            {
                node.AnchorPattern.Points[10].AllowIncoming = true;
                node.AnchorPattern.Points[10].AllowOutgoing = true;
                return 10;
            }
            if (!node.AnchorPattern.Points[14].AllowIncoming)
            {
                node.AnchorPattern.Points[14].AllowIncoming = true;
                node.AnchorPattern.Points[14].AllowOutgoing = true;
                return 14;
            }
        }
        return 0; // Shouldn't get here, but this makes the compiler happy !
    }
 

The AnchorPattern being used is as follows:

AnchorPattern taskAnchors2 =
            new AnchorPattern(new AnchorPoint[]
                {
                    new AnchorPoint(0, 16, false, false, MarkStyle.Rectangle, Color.Blue),
                    new AnchorPoint(0, 33, false, false, MarkStyle.Rectangle, Color.Blue),
                    new AnchorPoint(0, 50, false, false, MarkStyle.Rectangle, Color.Blue),
                    new AnchorPoint(0, 66, false, false, MarkStyle.Rectangle, Color.Blue),
                    new AnchorPoint(0, 83, false, false, MarkStyle.Rectangle, Color.Blue),
                    new AnchorPoint(100, 16, false, false, MarkStyle.Rectangle, Color.Green),
                    new AnchorPoint(100, 33, false, false, MarkStyle.Rectangle, Color.Green),
                    new AnchorPoint(100, 50, false, false, MarkStyle.Rectangle, Color.Green),
                    new AnchorPoint(100, 66, false, false, MarkStyle.Rectangle, Color.Green),
                    new AnchorPoint(100, 83, false, false, MarkStyle.Rectangle, Color.Green),
                    new AnchorPoint(16, 100, false, false, MarkStyle.Rectangle, Color.Red),
                    new AnchorPoint(33, 100, false, false, MarkStyle.Rectangle, Color.Red),
                    new AnchorPoint(50, 100, false, false, MarkStyle.Rectangle, Color.Red),
                    new AnchorPoint(66, 100, false, false, MarkStyle.Rectangle, Color.Red),
                    new AnchorPoint(83, 100, false, false, MarkStyle.Rectangle, Color.Red)
                }); 

As you can see I have disabled all anchor points, and only enable them as I need them.

I get the same incorrect results whether I use diagram.RouteAllLinks(); or not.

Here's my diagram settings:

diagram.DrawLink += OnDrawLink; // Add an event handler to draw images on links if they exist
        diagram.EnableShadowEffects = true;
        diagram.ShowGrid = false;
        diagram.GridColor = Color.LightGray;
        diagram.GridStyle = GridStyle.Lines;
        diagram.AlignToGrid = true;
        diagram.MeasureUnit = GraphicsUnit.Millimeter;
        diagram.LinkStyle = LinkStyle.Cascading;
        diagram.LinkCascadeOrientation = Orientation.Auto;
        diagram.DynamicLinks = true;
        diagram.EnableLanes = true;
        diagram.GridOffsetX = 4;
        diagram.GridOffsetY = 4;
        //diagram.Bounds = new RectangleF(0, 0, 500, 400);
        diagram.LinkCrossings = LinkCrossings.Arcs;
        diagram.EnableStyledText = true;
        diagram.PolygonalTextLayout = true;
        diagram.LinkSegments = 2;
        diagram.SnapToAnchor = SnapToAnchor.OnCreateOrModify;
        diagram.LinkEndsMovable = true;
        diagram.DefaultShape = Shapes.RoundRect;
        diagram.LinkTextStyle = LinkTextStyle.OverLongestSegment;
        diagram.RoundedLinks = true;
        diagram.ShowAnchors = ShowAnchors.Selected;
        diagram.AutoResize = AutoResize.RightAndDown;
        diagram.ContainersFoldable = true;
        diagram.LinkCascadeOrientation = Orientation.Auto;
        diagram.LinkRouter = new GridRouter();
        //diagram.LinkRouter = new QuickRouter();
        diagram.RouteLinks = true;
        diagram.RoutingOptions.Anchoring = Anchoring.Keep;
        diagram.RoutingOptions.CrossingCost = 50;
        diagram.RoutingOptions.LengthCost = 10;
        diagram.RoutingOptions.NodeVicinityCost = 5;
        diagram.RoutingOptions.TurnCost = 10;

        diagram.EnableLanes = true;
        diagram.LinkHeadShape = ArrowHeads.Triangle;
        diagram.LinkHeadShapeSize = 4;
        diagram.BackBrush = new MindFusion.Drawing.SolidBrush(Color.White); 

Any suggestions on what to try next?
Thanks again for all your help.

Jim

Hi,

I have set diagram.DynamicLinks = false; but with the same results.
Any other ideas?
Is there anything else I can provide you that would help?

Jim

Hi,

Creating a test project is next to impossible, but I have attached the class that renders the diagram.
It's big (and probably ugly), and it's database driven.
The method that creates the links is called "createConnector" and you can see where the origin and destination anchors are being set at lines 1512 and 1513.
The anchor points that are not working are for "task shapes" and are provided by method "getTaskAnchor". The AnchorPattern for these shapes is "taskAnchors2".
I have verified that this method is in fact returning the desired values.

The swimlane layout is applied at line 297 and the mainline code ends at line 346.

I hope your developer can gleam something from this.

Thanks in advance.

Jim

Hi,

Yes, I thought about that and commented the call to that method out, but with the same incorrect results.

I have attached a copy of the XML file as requested.
Please note this is for a different diagram  than I originally reported in this post (that one has since been deleted).
So, I've attached a screenshot of part of the diagram showing the origin anchorpoint numbers that were assigned to the shape titled "5.1 CT1".

Jim

Hi,

Great news.
Any idea when I could expect to see the release?
We're in a bit of a crunch right now and would like to get our app ready for system testing by Sep 27th.  Getting the code before then would be great.

Thanks

Jim

Hi,

I would prefer if your developer compiled it.
According to the properties, my MindFusion.Common.dll is at 1.3.0.20523 dated 3/13/2012 5:24 PM, and MindFusion.Diagramming.dll is at 5.8.0.17138 3/13/2012 5:24 PM.

Jim

Hi,

Looks like 4.2.
The WebForms.dll shows 4.2.0.30899.
