Three questions about ContainerNode:
1 Can caption text alignment be set?
2 Can caption brush be set separately?
3 How to set border style?
and another question:
Can mouse cursor be set hand when diagram behavior set 'Behavior.DoNothing',because need raise click node or link event.
Expecting your answer.

1 and 2 are not available out of the box. You could use the onUpdateVisuals custom-draw callback to implement them:

Code
Select All
var Alignment = MindFusion.Diagramming.Alignment;

container.onUpdateVisuals = onUpdateVisuals;

function onUpdateVisuals(node)
{
	node.text.textAlignment = Alignment.Center;

	var captionBar = node.getBounds().clone();
	captionBar.height = node.captionHeight;
	captionBar.brush = "red";
	node.graphicsContainer.content.splice(1, 0, captionBar);
}


You can use the setStroke and setStrokeThickness functions of DiagramItem to customize the border.

I hope that helps,
Stoyan

It's a well-guarded secret Smiley I think our developer added it to let someone add extra icons to nodes, and forgot to document it after that. You can find several examples in the ASP.NET MVC and JavaScript forum boards if you are interested in custom-drawing.
