Horozontal scrolling performance

[romsinParticipant]

Hello,

We are using jqxGrid for financial application which requires to display hundreds of columns. And we see real slowness. Our investigation showed that most of the time is the browser render since there are thousands of DOM elements there. So we’re looking in the horizontal virtualization similiar that jqxGrid has for vertical scrolling. Did anybody look in the same adjustments, probably jqx team has some plans for its implementation? We’re under the license with jqxGrid soruces and curious whether jqx team see any obstacles if we try to implement it on our own. Looking forward to comments.

Hi romsin,

Horizontal UI Virtualization is unfortunately not supported. At present, the Grid updates only the visible cells horizontally and vertically, but creates all HTML Elements required for Horizontal Scrolling. For vertical scrolling, only existing cells are updated, new elements are not created. If your target is to display hundreds of columns, the horizontal scrolling performance will be affected due to the amount of html elements that should be added to the page. I don’t think that horizontal virtualization would be easy for implementation and for now we do not have plans for such.
