Actually my angular version was in 9 and I downgraded it to angular 8 then I tried local data binding is working and also your suggestion is also working.
but I want to have it in Angular 9. I want the following features.
1) two data binding
2) lazy loading during virtual scroll
3) If I open excel with 1million rows entire application is loading for 2 to 3 mins and finally one pop up showing unsupported file. instead, it would be better if it shows something like one thousand first and then shows the rest of the record once the entire record is loaded.
4) I want pivot table functionality inside the spreadsheet
5) for now how can I capture the scrolling event
Could you please give me the time frame when will I get these features(all features are a bit urgent for me).
