Remove should work in this version:
https://mindfusion.eu/_beta/DiagramLite.0.9.3.zip

You cannot remove items from a collection while iterating over the collection, so you will have to use a second collection and loop:

Code
Select All
DiagramNodeCollection toRemove = new DiagramNodeCollection();
foreach (ShapeNode node is diagram.Nodes)
{
	if (!node.Selected)
		toRemove.Add(node);
	if (node.Text == "123")
		toRemove.Add(node);
}
foreach (DiagramNode node is toRemove)
{
	diagram.Items.Remove(node);
}


I hope that helps,
Stoyan
