[Elements] Moving cell editing focus by holding down the Tab key is slow in grid with 300+ cells in view. #16300
Description
Description
When the data view has many cells the change detection cycles are slow.
The exact number of cells needed to reproduce the delay depends on the machine and its performance, but for me it was somewhat noticeable with 300+ cells in view.
- igniteui-angular version:
- browser: any
Steps to reproduce
- Run the attached sample:
e2196946-f8d1-4c65-aec6-9225b61ac85f.zip
- Zoom out so that you see as many cells as possible. Around the first 10 rows should suffice (33cols x 10rows).
- Enter edit mode for the second cell and hit and hold tab to trigger navigation.
Note: Same happens in the angular grid, when there is many cells in the data view. For example, if you enable editing in the dev demo's performance sample and try tabbing, there will also be a noticeable lag.
Result
Navigation is a bit slow to respond. Also when you stop holding tab, it does not stop immediately.
Expected result
It should respond faster (if possible).
