Virtualization issues (19.4.0.56)
Hi
Virtualization on the SfPivotView control is inoperable on large volumes of data.
First, the horizontal scrollbar is no longer displayed when virtualization is active. However, it is when virtualization is inactive. The final user is therefore unable to view the data which is not displayed in the case where the virtualization is active. Not really acceptable by the end customer.
With virtualization active :
With virtualization inactive :
Second, data navigation is often unacceptable. Sometimes data does not display after a scroll. Above all, the are untimely reloads which sometimes bring us back to the data previously displayed when we have just scrolled. Totals do not always display. Not to mention the jerky scroll with incessant jumps that make you want to vomit. This even when trying to scroll slowly. It's very simple, there is data that I can't display. I can't find a precise line as the control jumps in one direction or the other. Impossible to put such a control in an application for an end customer.
Pagination would have minimized the effects and made the control usable. But there is no such option in your control.
All this is very unfortunate because your control is really great (apart from virtualization) and that's one of the reasons that made us choose your controls over the competition.
