Show or hide columns on exported PDF

You can show a hidden column or hide a visible column while exporting the Gantt using the toolbarClick and beforePdfExport events.

You can show or hide columns by setting the column.visible property to true or false respectively.

In the following example, there is a hidden column Duration in the Gantt. While exporting, we have changed Duration to visible column and StartDate to hidden column.

Conditional cell formatting

TreeGrid cells in the exported PDF can be customized or formatted using the pdfQueryCellInfo event. In this event, you can format the treegrid cells of exported PDF document based on the column cell value.

In the following sample, the background color is set for Progress column in the exported document by using the args.style and backgroundColor properties.
