After removing row by context menu, all red highlights changes positions rather than being on duplicate rows

please suggest how can i achieve validation after delete row also

Hey @shanksachan

you can try to load this logic into a function and call it via afterRemoveRow and afterCreateRow hook. If you enable row moving you should also consider adding afterRowMove.

Hey @aleksandra_budnik could you please give a fiddle demo using afterRowMove

I do not have any demo I can use and rebuilding your demo will take some time. You need to create an external method that you can call in all the hooks: afterChange, afterCreateRow, afterRemoveRow. Now it is impossible as you refer to the data via afterChange parameter. You need to keep it global.

So you don’t use

var changeLen = changes.length;

but you iterate the rows

var changeLen = hot.countRows()

As you’re making it global you just use hot and skip this var hotInstance = this;
