Hello,

i create a custom shape node and add this node to a nodelistview. Now i can drag the node to my diagram.
I select the node and copy and paste it. The node will be copied. New position is in the upper left corner of the diagram. I expect the node with some offset from origin position. What's wrong?
This is the code i create the node:

public class LogicGateNot : ShapeNode
    {
        public LogicGateNot()
        {
            InitNode();
        }

        // Required for creating nodes by dragging them from the NodeListView
        public LogicGateNot(LogicGateNot prototype)
            : base(prototype)
        {
            InitNode();
        }

        private void InitNode()
        {
            // comment out the next line and copy/paste will work correctly
            this.SetBounds(new Rect(0, 0, 100, 100), true, true);
        }

        public override void Draw(System.Windows.Media.DrawingContext graphics, RenderOptions options)
        {
            graphics.DrawRectangle(Brushes.Transparent, new Pen(Brushes.Red, 1), new Rect(0, 0, 100, 100));
            //base.Draw(graphics, options);
        }
    }
 

When i set the width/heigth to 100/100 the error (for me ) occurs. When i comment out the SetBounds function the default width/heigth is 75/75, but this is to small.

Thank you

Perfect! It's working!
