Collapse groups with endless virtual scrolling

[Alex]

If I use endless scrolling and grouping all seems to work alright, except when I go to collapse the groups. Is this supposed to be supported? When I  try to collapse the group nothing happens.

Hello, Alex,

Thank you for the information.

We have a same issue as the described one when the Grid has locked columns. 

I'm glad to inform you that it is already fixed and it will be available in the next official release:

If the issue is different, please provide an example and we will gladly investigate further.

Regards,
