Error in sortBy if grid is not visible

[pguzParticipant]

Hi,

I have experienced an error if attempting to sort a grid that is not visible (e.g. is in a non-visible tab). I am using jqWidgets v3.0.4 with jQuery 1.7

An uncaught exception is thrown at line 1738 of jqxgrid.js, in _updatehiddenrows, where it attempts to access the hiddenboundrows collection, which in this case is undefined.

The quick fix is simply to wrap a try..catch around the call to ‘sortby’ – the sort still seems to happen despite the error. A more correct fix is to ensure the sort only takes place when the grid is visible.

However, I also suggest to those at jqWidgets that a fix is added to _updatehiddenrows in jqxgrid.js to check for hiddenboundrows being undefined, to prevent the error from occurring in the first place.

Hello pguz,

Thank you for your feedback. We will consider improving this functionality, but for now, you can sort a grid successfully only when it is displayed.

This problem also exists in just initializing a grid that is hidden as of v3.9.0. The suggested fix to _updatehiddenrows is not much work and should be implemented.

Hello DennisDupont,

A general rule for jQWidgets controls is that they cannot be initialized when their display is none. A working alternative is visibility: hidden;. More information on this matter is given in the following forum post: http://www.jqwidgets.com/community/topic/jqxgrid-refreshing-while-ng-show-with-filterrow-js-error/#post-81054.
