pdf.proxyURL String (default: null)

The URL of the server side proxy which will stream the file to the end user.

A proxy will be used when the browser isn't capable of saving files locally. Such browsers are IE version 9 and lower, and Safari.

The developer is responsible for implementing the server-side proxy.

The proxy will receive a POST request with the following parameters in the request body:

  • contentType: The MIME type of the file
  • base64: The base-64 encoded file content
  • fileName: The file name, as requested by the caller.

The proxy should return the decoded file with the "Content-Disposition" header set to attachment; filename="<fileName.pdf>".

Example - set the server proxy URL

<div id="treelist"></div>
    toolbar: ["pdf"],
    columns: [
      { field: "FirstName", title: "First Name" },
      { field: "LastName", title: "Last Name", width: 160 },
      { field: "Position" }
    pdf: {
      proxyURL: "/save"
