we want to put a 15k * 20k table in grid. We just virtualize the Row data(we read whole record each time). But it is still very slow. So we suspect the Grid create all the cell for each record even the cell is not displayed on the screen.
Could you give us some advices on how to improve the performance?
Nothing, I have the same problems and the only way to improve a bit the situation is to set a fixed height...
Matt,
I've further increased the number of columns due to business need then the VS profiler shows different hot path, see attached for detail. Please advise whether there is anything we can do to improve it, thanks.
Thanks sgrignola, that does help, although just a little bit, about 10%, which is still far from what we need. Did you set any other property for row height?
Check the FieldSettings or the FieldLayoutSettings, you should find something like CellHeight
Hi sgrignola,
How did you set the row height?
