Usage

Export Listbox/Grid

As you can see the following sample code, export Listbox/Grid to PDF or Excel is quite straightforward. Create a exporter and invoke export API.

PDF

	@Command
	public void exportGrid(@BindingParam("ref") Grid grid) throws Exception {
		ByteArrayOutputStream out = new ByteArrayOutputStream();
		
		PdfExporter exporter = new PdfExporter();
		exporter.export(grid, out);
		
		AMedia amedia = new AMedia("FirstReport.pdf", "pdf", "application/pdf", out.toByteArray());
		Filedownload.save(amedia);		
		out.close();
	}

Excel

	@Command
	public void exportListboxToExcel(@BindingParam("ref") Listbox listbox) throws Exception {
		ByteArrayOutputStream out = new ByteArrayOutputStream();
		
		ExcelExporter exporter = new ExcelExporter();
		exporter.export(listbox, out);
		
		AMedia amedia = new AMedia("FirstReport.xlsx", "xls", "application/file", out.toByteArray());
		Filedownload.save(amedia);
		out.close();
	}

Export data by Renderer

Although export Listbox/Grid to PDF or Excel is quite straightforward. However, it does have some limitation. For instance, it cannot export full contents with Grid/Listbox ROD enabled. In such use case, you can use renderer to render raw data to PDF/Excel directly.
