Highlighting Nodes Attached to Links

How do I highlight a node attached to a link?

The nodes attached to the link are ControlNode and CompositeNode.

---
Tried and tested method:
When the link is selected, set the property (Selected) of the node attached to the link to true.
However, the LinkModifying event does not occur and I cannot move the destination or source of the connection.

Once you select multiple items, you get SelectionMoving event when they are moved, and links' origin / destination cannot change through a multiple-selection. You could draw highlights from DrawForeground event handler instead of selecting attached nodes:

Code
Select All
void OnDrawForeground(object sender, DiagramEventArgs e)
{
	foreach (var link in diagram.Selection.Links)
	{
		if (link.SubordinateGroup != null)
		{
			foreach (var attached in link.SubordinateGroup.AttachedNodes)
			{
				var rect = attached.Bounds;
				rect.Inflate(2, 2);
				e.Graphics.DrawRectangle(Pens.Green, rect);
				//or attached.DrawHandles()
			}
		}
	}
}

I tried it as soon as possible.
It works as expected.
