CustomNodeId

Node.CustomNodeId property

Specifies custom node identifier.

public int CustomNodeId { get; set; }

Remarks

Default is zero.

This identifier can be set and used arbitrarily. For example, as a key to get external data.

Important note, specified value is not saved to an output file and exists only during the node lifetime.

Examples

Shows how to traverse through a composite node’s collection of child nodes.

Document doc = new Document();

// Add two runs and one shape as child nodes to the first paragraph of this document.
Paragraph paragraph = (Paragraph)doc.GetChild(NodeType.Paragraph, 0, true);
paragraph.AppendChild(new Run(doc, "Hello world! "));

Shape shape = new Shape(doc, ShapeType.Rectangle);
shape.Width = 200;
shape.Height = 200;
// Note that the 'CustomNodeId' is not saved to an output file and exists only during the node lifetime.
shape.CustomNodeId = 100;
shape.WrapType = WrapType.Inline;
paragraph.AppendChild(shape);

paragraph.AppendChild(new Run(doc, "Hello again!"));

// Iterate through the paragraph's collection of immediate children,
// and print any runs or shapes that we find within.
NodeCollection children = paragraph.GetChildNodes(NodeType.Any, false);

Assert.AreEqual(3, paragraph.GetChildNodes(NodeType.Any, false).Count);

foreach (Node child in children)
    switch (child.NodeType)
    {
        case NodeType.Run:
            Console.WriteLine("Run contents:");
            Console.WriteLine($"\t\"{child.GetText().Trim()}\"");
            break;
        case NodeType.Shape:
            Shape childShape = (Shape)child;
            Console.WriteLine("Shape:");
            Console.WriteLine($"\t{childShape.ShapeType}, {childShape.Width}x{childShape.Height}");
            break;
    }
