Hello,
When you have lots of columns (over 2000) each with a summary calculation, it is very slow to display. I have determined this is because the control seems to try to calculate every summary value even if the column hasn't been shown on the screen yet (using the scrollbars).
Is there a way to stop the summary calculator from calculating the values in the column until the column is actually scrolled to by the user?
Thanks,
Doug
Thanks for that. I should have spotted it I guess.
On testing it works apart from when the summary is initially set to SummaryDisplayAreas.None and then changes to SummaryDisplayAreas.BottomFixed.
When we set it to the BottomFixed value it does not display automatically. Do I need to do something extra here?
THanks,Doug
You can set the SummaryCellContainerGenerationMode on the control. By default the summary cells are preloaded.
