Hello,

currently I have the following problem:

I implemented my own ShapeTemplate which holds additional information (like a second Box in a class called Textlabel).

When I paint a diagram, all information is displayed correctly and everything works well. After saving and loading the diagramm, the following occurs:

The ShapeTemplate is in memory (displayed correctly and everything), but the additional information holds no information anymore.

Here is my code, first the shapeTemplate:

    [Serializable()]
    class Shapes3682 : ShapeTemplate
    {
        public Color bgColor;
        public static FillMode fillMode = FillMode.Winding;
        public TextLabel label;

        public Shapes3682(ElementTemplate[] elements, String shortName)
            : base(elements, fillMode, shortName)
        {
        }

        public void createTextLabel(Box icon, String text, int textPosition)
        {
            label = new TextLabel(icon, text, textPosition);
        }
    }
 

and the code for the Textlabel:

    [Serializable()]
    class TextLabel
    {
        private int iTextPosition;
        private Box label;

        public TextLabel(Box icon, String text, int TextPosition)
        {
            iTextPosition = TextPosition;
            label = new Box(icon.Parent);
            label.Text = text;
            label.BoundingRect = new RectangleF(PointF.Empty,
              icon.Parent.MeasureString(label.Text, label.Font, int.MaxValue, label.TextFormat));
            label.Transparent = true;
            label.Locked = true;
            label.PolyTextLayout = true;
            label.FitSizeToText(FitSize.KeepRatio);

            icon.Parent.Add(label);
            //// attach the label to the icon
            RectangleF rc1 = icon.BoundingRect;
            RectangleF rc2 = label.BoundingRect;
            label.BoundingRect = getBoundingRect(ref rc1, ref rc2);
            label.AttachTo(icon, AttachToNode.BottomCenter);
            icon.SubordinateGroup.AutoDeleteItems = true;
        }
}
 

After reloading the diagram, the label from the ShapeTemplate class is set to null .

I can't figure out why the information is not stored.

Can anyone help?

Best regards,

Alex

Ok, thank you for the fast response. Something else is already saved in the Box. Tag so I'll have to figure out a different way.

Thank you very much for saving me a lot of trouble shooting
