Exporting filtered data in EJ2 TypeScript Treegrid control

27 Apr 20235 minutes to read

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

In the below Pdf exporting demo, We have gotten the filtered data from the filteredResult of Tree Grid filterModule and then defines the resulted data in PdfExportProperties.dataSource and pass it to pdfExport method.

import { TreeGrid, Page, Toolbar, PdfExport, Filter } from "@syncfusion/ej2-treegrid";
import { projectData } from './datasource.ts';
import { ClickEventArgs } from "@syncfusion/ej2-navigations";

TreeGrid.Inject(Page, Filter, Toolbar, PdfExport);

let treegrid: TreeGrid = new TreeGrid({
  dataSource: projectData,
  idMapping: "TaskID",
  parentIdMapping: "parentID",
  treeColumnIndex: 1,
  allowPaging: true,
  allowFiltering: true,
  pageSettings: { pageSize: 5, pageCount: 5 },
  allowExcelExport: true,
  allowPdfExport: true,
  toolbar: ["PdfExport"],
  toolbarClick: toolbarClick,
  columns: [
    { field: "TaskID", headerText: "Task ID", textAlign: "Right", width: 70,
    { field: "TaskName", headerText: "Task Name", width: 100 },
    { field: "StartDate", headerText: "Start Date", textAlign: "Right", width: 100,
      format: { skeleton: "yMd", type: "date" } },
    { field: "EndDate", headerText: "End Date", textAlign: "Right", width: 100,
      format: { skeleton: "yMd", type: "date" } },
    { field: "Duration", headerText: "Duration", textAlign: "Right", width: 90 },
    { field: "Priority", headerText: "Priority", width: 90 }
  ]
});
treegrid.appendTo("#TreeGrid");
function toolbarClick(args: ClickEventArgs) {
  if (treegrid && args.item.text === "PDF Export") {
    let pdfdata;
    pdfdata = treegrid.filterModule.filteredResult;
    const exportProperties = {
      dataSource: pdfdata
    };
    if (treegrid) {
      treegrid.pdfExport(exportProperties);
    }
  }
}
