Exporting Filtered Data Only

You can export the filtered data by defining the resulted data in exportProperties.dataSource before export.

In the below Pdf exporting demo, We have gotten the filtered data by applying filter query to the grid data and then defines the resulted data in exportProperties.dataSource and pass it to pdfExport method.
