I need to be able to display a pagination of 200 rows in my table. I have page sizes of 25, 50, 100 and 200.
The performance of the grid is acceptable when it renders only text, even for a page size of 200 rows.
But sometimes, I need to render custom cells... I tried using both approaches of column templates and queryCellInfo method. I find the performance of queryCellInfo acceptable at 25 and maybe 50 rows. But it is slow at 100 rows (3-4 seconds for rendering only) and very slow at 200 rows (+7 seconds for rendering). For column templates it is even worse, it takes like double the time of queryCellInfo.
My custom templates vary between a simple icon and a button with click handler.
Is this performance expected or am I doing something wrong?
I also had a look at virtualization as a solution for this issue, but I need to display the pagination in my table. I don't think both pagination and virtualization can be implemented at the same time. correct?
