i implemented ‘updateRow’ in setInterval to update UI every 20 ms.but when user try to sort the grid.. whole page becomes unresponsive.is this because i am calling ‘updateRow’ while sorting is being under process ?? how can i fix it ??

[jahnvi25Participant]

well. i do have question.when we use in-built sorting, ‘bindingComplete’ does not get called. but when we use custom sorting. it does.. is there a way to avoid this and still use custom sorting ?

[jahnvi25Participant]

i need old rows before sorting on current page.. so that on serverside,i need to process.. and then after sort.. i will have new set of data on same page.. so i will get new visible rows?

how can i get old data (only displayed on current page) before sorting

[jahnvi25Participant]

well.. documentation says following
——-
pager: function (pagenum, pagesize, oldpagenum) {
// callback called when a page or page size is changed.
}
——-

and i dont see console.log when i change page..so according to API it should have oldpagenum

[jahnvi25Participant]

never mind.. ignore this.. i figured out a way

[jahnvi25Participant]

thanks for reply. i got approval from our business manager to use paging.. so that should improve performance.also i am planning to use updaterow method. but do you suggest that i keep collecting data for certain period of time.. and then update grid using ‘updaterow’ method ?
also is there a way i can get visible rows beforesort.. (like old visible rows).. then after sort.. i get new set of rows as a result of sort or filter?

again thanks for help.

[jahnvi25Participant]

thanks for reply. but i do have question about pagination.if we use that pagination, does it only render visible rows on page ? how can i get only visible rows on any given page. and how would this impact when user performs sort or filter ? i still would have to use ‘setcellvalue’ to update data.

[jahnvi25Participant]

this is a big complains from our customers as well.. is there a way we can control.. or may be jqxwidget can make scrolling better on mac >

[jahnvi25Participant]

i am using ‘beginupdate’ and ‘endupdate’ because i am updating multiple cells on same row.. but performance is not good.. i already went to other link that you suggested.but that does not give me solution.

i was thinking of using ‘datatable’.. but i found from forum that this widget does not handle scrolling of large data set. do you think paging would help improving performance..like display 50 rows per page.. the only question i have.. using pageing.. when user sorts.. how would i get latest rows that displays on page (after sort) and would that impact rowId ?

Thanks

[jahnvi25Participant]

one more question on same thing.. do you think by using datatable instead of jqxgrid would make difference ? (performance wise). currently because of too many updates on screen for long time. browser is becoming un-responsive. and i have to ‘force quit’,which is not acceptable at all..

[jahnvi25Participant]

any help please..

[jahnvi25Participant]

thanks.. its working for now.

[jahnvi25Participant]

i tried to call ‘updatebounddata’ after i do

$(“#jqxgrid”).jqxGrid(‘setcellvalue’, rowId, “volume”, obj.accumulatedVolume);

$(“#jqxgrid”).jqxGrid(‘updatebounddata’,’cells’);

but this is not working.. by using just “setcellvalue” it does refreshing grid. but if i use “udatebounddata” then it does not change value on screen at all..

how can i use it correctly so that it can refreshes the cell value as well..

[jahnvi25Participant]

just the example in the list.. meaning. with data table i want to open/close groups just like jqxgrid ?

[jahnvi25Participant]

here is the more info what our users are facing. this is specific to Mac os..

https://github.com/jquery/jquery-mousewheel/issues/36

that describe the issue in details. and looks like ‘wheel delta’ is not set properly in any of the jqx component. i tried jqxgrid and jqxdatatable.. they all behave same way on mac os.. windows os works fine.
