Hi,

I have attached a sample screenshot of what I am looking to do.
From the documentation, it would appear that I should perhaps be looking at a ContainerNode.  Is this correct?  Am I on the right path?

The main shape (a task) can have zero or more of the child shapes illustrated in the bottom right corner.  I am using ImageMap and the main shape and the child shapes must respond to a NodeClick as well as support a tooltip.  The shapes will all be produced programmatically on code behind.

I searched the latest beta 5 samples for ContainerNode and came up with nothing, and the documentation really doesn't provide a "cookbook" approach - it's more of a reference guide.

Anyway, can you either provide me with an overall approach, or (as you have in the past), some code snippets that would get me going.

We're looking at taking our current diagrams to a new level and this capability will certainly help us out a lot.

Thanks in advance.

Jim

Hi,

Thanks for the tips.
I am having 2 challenges.
If I use AttachTo while I am creating the shapes, I get the result shown in the attached screenshot.
The 3 blue circles should be located at the BottomRight of the shapes to their left.

If I wait until after I have called the "arrange" method, I call the following functions:

protected void getAnnotations(Diagram diagram)
    {
        Factory factory = diagram.Factory;
        DiagramNodeCollection allNodes = diagram.Nodes;
        foreach (ShapeNode node in allNodes)
        {
            if (node.Shape == Shapes.RoundRect) // A task shape
            {
                // Attach an annotation node - POC
                ShapeNode annotationNode = factory.CreateShapeNode(0, 0, 3, 3, Shapes.Ellipse);
                MindFusion.Drawing.SolidBrush annotationShapeFill = new MindFusion.Drawing.SolidBrush(Color.Navy);
                annotationNode.Brush = annotationShapeFill;
                annotationNode.Tag = "annotation";
                annotationNode.ToolTip = "This is an annotation";
                //annotationNode.Transparent = true;
                AttachToParent(diagram, annotationNode, node.Id);
            }
        }
    }

    protected void AttachToParent(Diagram diagram, ShapeNode childNode, Object parentID)
    {
        DiagramNode parent = diagram.FindNodeById(parentID);
        childNode.AttachTo(parent, AttachToNode.BottomRight);
    } 

This results in the following exception:

"Collection was modified; enumeration operation may not execute."

Any suggestions as to how to proceed?  When exactly should I be executing the AttachTo method?

Thanks

Jim

Hi,

Great advice.  I've made some progress, but am still having challenges.

It seems that regardless of the AttachToNode setting, the shape is placed in the TopLeft of the master shape.  See attached screenshot.

I tried both IgnoreLayout and KeepGroupLayout and they work as far as ensuring that the annotation shape "sticks" with the parent, but I can't get it anywhere other than the top left.

I had some other code after the arrange method, but I disabled all of that and the problem persists.

Any suggestions.

Thanks again.

Jim

Stoyan,

This worked great.
Thanks for the advice and code.

Jim
