Hi Prabhat,
Greetings from Syncfusion Support,
We have validated the reported issue on our end. A sample was prepared and
tested using the shared Gantt chart configuration. We were able to replicate
the issue when exporting 200 records to PDF. During export, the Gantt chart
becomes unresponsive and shows a delay message. This occurs because the export
process generates a timeline-based layout across multiple pages, which takes
time to render and export.
Currently, it is not possible to restrict the timeline range
during PDF export. However, to reduce export time, we recommend reducing the
page size. This will decrease the number of pages generated, and as a result,
the export will complete faster.
For example, using a smaller pageSize (like 'A0')
significantly reduces the export time for 200 records to just a few seconds.
Please refer to the following code snippet and the attached sample:
|
<ejs-gantt
#gantt id="SplitTasks" [toolbar]="toolbar" (toolbarClick)="toolbarClick($event)"
...
[allowPdfExport]="true"
>
</ejs-gantt>
toolbarClick(args?: any): void {
if
(args.item.id === "SplitTasks_pdfexport") {
let exportProperties: PdfExportProperties = {
pageSize : 'A0'
};
this.ganttObj.pdfExport(exportProperties);
}
}
