Hello Hristo,
Thank you for your reply. I think the point from that topic is that virtualmode with grouping is not supported. I can understand that, although it is very unfortunate for us. We are using this on read-only grids (no editing) and have not noticed any other issues with the grouping functionality, except this scenario when there are only a small number of records to display. If we have at least 1 page of data, we do not see this issue. The grouping functionality is very helpful for our use case, in spite of it naturally only grouping a single page of data at a time.
Is there any chance you would consider fixing this read-only scenario for grouping in combination with virtualmode?
Thank you again.
