Description

How can I include the hidden columns in the exported PDF file of the Grid?

Solution

1. Show the hidden columns by using the showColumn method within the pdfExport event handler.
2. When the PDF export is done, hide the columns that are not intended to be visible by using the hideColumn method.

      <div id="example">
      <div id="grid"></div>
      <script type="x/kendo-template" id="page-template">
      <div class="page-template">
        <div class="header">
          <div style="float: right">Page #: pageNum # of #: totalPages #</div>
          Multi-page grid with automatic page breaking
        </div>
        <div class="watermark">KENDO UI</div>
        <div class="footer">
          Page #: pageNum # of #: totalPages #
        </div>
        </div>
      </script>
