Thank you Peter

Currently I’m using rather nasty workaround, where on every checkChange allItems are retrieved, looped over and counter is incremented until match with currently clicked item is found. But there must be a better way

[PeterZParticipant]

thank you!

but how do I know by what number should I increment the index?

E.g.: https://jsfiddle.net/3hkoyLn9/

I want to update the checked item with “hello”. Try to click on any item in second group – it will rename the group

Hello,
thanks a lot! Good idea.

I ended up using combination of getfilterinformation and addfilter. It was 7 times faster than getstate and loadstate

Also applying filters this way caused grid to scroll to the top (first row), so I also saved the scroll position (scrollposition) and then after applying filters scrolled to previous position scrolloffset

By slower I meant performance-wise, not by typing code

Consider this example:
http://jsfiddle.net/myzd78o2/

Press the button and see console for how many milliseconds it took to execute the code.

Updating 100 rows using loop over individual row takes ~1500ms

Updating the same 100 rows using one call of updaterow with array takes 20ms, but has the bug that prevents it to use it together with filter.

So the question is if there is workaround that will allow to updaterows with filter applied and it won’t be that much slower. 1500ms is huge performance hit, especially when it is called regularly.

Thank you!

Hello,
is there any workaround?

What works is to use
$("#grid").jqxGrid('updaterow', "C", newRowC);
$("#grid").jqxGrid('updaterow', "D", newRowD);

instead of

$("#grid").jqxGrid('updaterow', ["C", "D"], [newRowC, newRowD]);

But it is much slower (e.g. I try to update 100 rows at once).

Thanks!
