Hello, I wnat lock nodes in order to prevent acidentally move of node.

var nodestolock = form.Selection.Nodes.Clone();
            foreach (DiagramNode node in nodestolock)
                {
                  node.EnabledHandles = AdjustmentHandles.None;
            
                }      

This work perfect, anyway there is a problem, when use the arrow keys and select multiple nodes, the locked nodes move.
How I can prevent node locked with AdjustmentHandles.None not be moved by arrow keys?

I need some way make if select multipple nodes and one is locked, user cnat move until is unlocked.

To unlock i use:
  foreach (DiagramNode node in nodestounlock)
                {
                    node.EnabledHandles = AdjustmentHandles.All & ~AdjustmentHandles.Rotate;
                }
                foreach (DiagramNode node2 in nodestounlock)
                {
                    node2.HandlesStyle = HandlesStyle.Custom;
                }

All work ok, just need prevent selected nodes are locked cant be moved.

Here the fix, but work some times,

form.CommandBindings.Add(new CommandBinding(Diagram.NavigateRight, (sender, args) =>
{
DiagramNode node = form.ActiveItem as DiagramNode;
if (node != null)
foreach (DiagramNode SelectedNode in form.Selection.Nodes)
{
if (node.EnabledHandles!= AdjustmentHandles.None)
SelectedNode.Move(SelectedNode.Bounds.X + ultrareso, SelectedNode.Bounds.Y);
}
}));



This work ok if i select single nodes, but if select multiple nodes and one is locked and other no, when i presss the key all nodes move.
Some ssugestion?
