I have a large editable grid, with a mix of header filters and footer sums.
The grid has 300 columns and approx 500 rows and is attached within a layout cell. The first 5 columns are fixed so do not scroll.
The scrolling performance of the grid is very slow. It updates once or twice a second when I try to scroll, which makes it very difficult to scroll to a column or row.
Are there any tips or suggestions that could make this faster?
