Ok so when we set SummaryCellContainerGenerationMode to LazyLoad (because too many columns to do in preload), the problem is that the grid does not calculate how many summary definitions have been added per column, so it only shows the first row of the definitions, even if they have been added in the XAML.
This is definitely a bug in 12.2. Has it been resolved in a patch or new version?
Thanks,Doug
HI Andrew,
Im not at my computer now but it is easy to replicate the group by issue. Just create a custom Summary Calculator and put a breakpoint on the begin calculation method and you will see that if you are not using a group by, only the visible fields are calculated. If you use a group by, all fields are calculated.
I was trying to do a solution myself to this by stopping the aggregate method if the field is not visible, but I havent yet managed to find a way to tell if a field is visible or not (as in within the scrollable viewing window) from the summary result/source field object (I posted another query about that). So if you are able to help with that query I may be able to do a workaround to the LazyLoad group by issue.
The part about the height of the record not updating seems like a bug. I mean we're essentially treating the element as virtualized in which case we don't really consider the height of the element but in the case of the summaries we should probably consider the element we have there because we have no template element to fall back to. The part about summary cells within the group by not virtualizing I'm not sure. You could probably create a sample we can review it and write up an issue about it if needed. Perhaps we're considering the wrong fields when dealing with a summary - e.g. we're looking at the list of fields that are available for data virtualization.
Sorry, should have checked the options tab.
When you reply to the post you can go to the options tab and add the attachment.
I have a sample project that shows the issue Im having. How can I upload it to you?
