PDF Export

The Diagram provides a built-in PDF export functionality.

For a runnable example, refer to the demo on exporting the Diagram to PDF.

Getting Started

To enable PDF export in the Diagram:

  1. Introduce a button and handle its click event. Export the Diagram within the handler.

        <button class='export-pdf k-button'>Save as PDF</button>
    
        <script>
            $(".export-pdf").click(function () {
                $("#diagram").getKendoDiagram().saveAsPDF();
            });
        </script>
    
  2. Include the Pako Deflate library in the page to enable compression.

To enable PDF export in the Diagram through code, call the saveAsPdf method.


    <button class='export-pdf k-button'>Save as PDF</button>

    @(Html.Kendo().Diagram()
          .Name("diagram")
          .Pdf(pdf => pdf
              .FileName("Kendo UI Diagram Export.pdf")
              .ProxyURL(Url.Action("Pdf_Export_Save", "Diagram"))
          )
          .DataSource(dataSource => dataSource
              .Read(read => read
                  .Action("Pdf_Export_Read", "Diagram")
              )
              .Model(m => m.Children("Items"))
          )
          .Editable(false)
          .Layout(l => l.Type(DiagramLayoutType.Layered))
          .ShapeDefaults(sd => sd
              .Visual("visualTemplate")
          )
          .ConnectionDefaults(cd => cd
              .Stroke(s => s
                  .Color("#979797")
                  .Width(2)
              )
          )
          .Events(events => events.DataBound("onDataBound"))
    )

    <script>
        $(".export-pdf").click(function () {
            $("#diagram").getKendoDiagram().saveAsPDF();
        });

        function visualTemplate(options) {
            var dataviz = kendo.dataviz;
            var g = new dataviz.diagram.Group();
            var dataItem = options.dataItem;

            g.append(new dataviz.diagram.Rectangle({
                width: 210,
                height: 75,
                stroke: {
                    width: 0
                },
                fill: dataItem.ColorScheme
            }));

            /*

            g.append(new dataviz.diagram.TextBlock({
                text: dataItem.FirstName + " " + dataItem.LastName,
                fontFamily: "DejaVu Sans",

        function onDataBound() {
            this.bringIntoView(this.shapes);
        }
