Hi,

The standard Behavior.DrawLinks lets you select existing items and draw new links. You can disable resizing by setting nodes' EnabledHandles property to AdjustmentHandles.Move value, or by setting their HandlesStyle property to HandlesStyle.MoveOnly.

If you are still using custom link types, you will also need to replace this factory function with one creating your link class instances -

DrawLinksBehavior.prototype.createLink = function (origin, point)
{
	var link = new mdiag.DiagramLink(this.diagram, origin, point);
	link.originConnection.chooseBestAnchorPoint(point);
	return link;
} 

You could as well create a complete class derived from BehaviorBase. There's not CustomBehavior public API declared as in Silverlight version, but you can still assign your instance to the Diagram.currentBehavior field.

You can assign handles color to diagram.handleBrush from client code. You can specify mark size through AnchorPoint constructor; if you need to change it for a pre-defined pattern, loop over its points array and call AnchorPoint.setSize.
