I have handsontable with Header checkbox and each row contain checkbox. when user click on header checkbox, all row level checkbox get selected. we are facing performance issue when more than 3000 or 4000 records in handsontable. It takes time checked. It takes more time when your are using filters.
we are using setDataAtRowProp to check the checkbox.
Handsontable checkbox performance issue
Hi @atj15295
this operation calls renderer many times and that is why you are facing performance issues.
Currently this way is the fastest for checkbox toggle http://jsfiddle.net/8b35uhf4/
