enableVirtualization + allowGrouping

Asked On March 21, 2019 01:51 PM UTC


I am trying to allow grouping for my Grid.
Without enableVirtualization  set to true, the column grouping works pretty well. But when I'm having more than 1000 data, it starts to be very slow..
So I set the enableVirtualization  to true and the performances are good again but when I group my column, the scroll inside groups fails. I cannot close a grouping and then scroll down to the other regroupment.

Cant you help me?

Here is an example you can group by the column name "Designation", close the first group and then scroll down.

Thank you in advance,

Hi Bernard, 

Thanks for contacting Syncfusion support. 

The grouping feature with virtualization support has been enhanced in our Volume 1, 2019 beta release. We have modified the CDN link for the EJ2 Script to the 17.1.32-beta version in the sample. Please refer to the below sample and give it a try.
