jqxGrid hiding rows with virtualmode and expanded groups

[aheileParticipant]

I am using the Angular 5 jqxGrid and have come across an issue with virtualmode in combination with expanded groups. If I only have a small set of data – not even enough to make one visible page – some of the data rows are hidden. It seems as though I only get enough visible rows in the grid for the amount of totalrecords, and it doesn’t leave enough visible rows when I also have groups expanded.

I worked up a small fiddle which I think demonstrates the problem with jqxGrid:

Hello aheile,

I would like to suggest you look at this forum topic:

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.

Or if you have suggestions for workarounds, that would also be appreciated. Thank you!

Hello aheile,

This question is more a philosophically.
Because how to group items that do not exist.
The all data in virtual mode is loaded on demand.
That I would like to suggest you try without ‘virtual-mode’.
We have a demo with 30k records without this feature:
