Hi Yuri,
Thanks for contacting Syncfusion support. Please find the response below.
We have checked your query. And, currently we don’t have support “To provide event for exporting by toolbar”. And, we logged this as feature in our features database. This will be included in our Essential Studio Volume 3 SP1 release which will be estimated to be available by the end of October, 2019.
Please let us know if you have any concerns.
Regards,
Scintilla A
