Hi Pablo,

If you need to add a hosted control:

Code
Select All
var button = new Button();
var node = new DiagramNodeAdapter(diagram, button);
node.Bounds = new Rect(33, 33, 333, 333);
diagram.Nodes.Add(node);


I hope that helps,
Stoyan

Ups, by error, i delete the original post jijij, sorry

One more question:

Exist some way to lock some kind of node for prevent deletion of that specific node.
I want this node can be only moved not resized, but never deleted, even if run diagram.ClearAll();
I no think this is possible but if possible, please tellme, need lock a specific kind of node for not delete.
Bets regards.

private void form_NodeDeleting(object sender, NodeValidationEventArgs e)
     {

        if (e.Node.UIElement is MyCustomNode)
        {
            e.Cancel = true;
        }
            
     }



This work when i try delete node using delete, but when i run form.ClearAll(); is deleted anyway.
Is possible pskip deletion when use ClearALL ?

You will have to either create the node again, or do something like this:

diagram.Nodes.Remove(theNode);
diagram.ClearAll();
diagram.Nodes.Add(theNode);

Only by removing it from the selection first, or immediately deleting the copy after calling Paste.
