Hi
Seems like I am able to host the datexport, but FYI you have a typo in code for CSV files. I changed from CVS to CSV for it to work

$mimeTypes = array(‘xls’ => ‘application/vnd.ms-excel’,
‘xml’ => ‘application/xml’,
‘html’ => ‘text/html’,
‘cvs’ => ‘text/plain’,
‘tsv’ => ‘text/plain’, ‘json’ => ‘text/plain’, ‘array’ => ‘text/plain’);

Hello,
I just purchased developer license. I do not understand how I host the exporter. Where is dataexport.php in production download of JQW 9.0. Where are exportsetttings?

Thanks.

Hello,
Still wondering if this issue has been resolved? Still appears to be present. Can you please offer a work-around?
It’s very difficult to offer filterrow option and grouping when users find error almost immediately.
Thanks.

Hello Todor,
I noticed that a new version of of jqwidgets was released – 8.3.2 but still experience this issue in my app. Has this been addressed in any way?

I have updated my fiddle to show the behavior which appears to occur when there are more than eight(8) columns present.

Please let me know.

Thanks.

Hello,
I am stuck for the right answer. When I add a window resize event to refresh any grids when window or splitter resize event occurs, all groups are always collapsed. If I remove the events then the grid does not correctly repaint on resizes. The demo above is ok but please see screen shot for actual behavior.

Please help. Prototypes/demos are failing.

Thanks.

Hi Hristo,
Is there been any more info on this?
Thanks.

Hi Hristo,

I am updating grid
myGridSource.localdata = mynewdata;
$(‘#mygrid’).jqxGrid(‘updatebounddata’, ‘cells’);

Is this not the correct way? Update localdata and then ‘updatebounddata’? I’m not sure I follow what you’re suggesting. I certainly have to refresh localdata first, right?

If you speak to you colleagues about memory please let me know.
Thanks!

Hello Hristo,
Thanks for your response. To further clarify the issue please look at one of your demos here: https://www.jqwidgets.com/jquery-widgets-demo/demos/jqxgrid/index.htm#demos/jqxgrid/loadfromtable.htm

With this page initially open Chrome task manager shows about 60,000K. After several clicks of the “Load jqxgrid from table” button the memory quickly grows. I then added a simple test in the chrome console to mimic a “realtime” app and fire the click event every second, as such:
myinterval = setInterval(function(){ $('#loadButton').click(); }, 1000);

With the page in focus I continue to see memory rise for this simple load operation – 60mb, 70, …200mb. Very rarely releasing memory via GC.

Also keep in mind that the grid I’m using has cell renderers which I assume adds to memory.

In my situation I am updating grid every 10-20 seconds; when leaving the page open for 2+ hours the memory can bloat to 500+mb; overnight and it crashes the browser,

Does this help clarify the situation?

Please let me know if you can shed any more light on this.

Thanks!
Rob

As a follow-up, when trying to GROUP after toggling filter row ON/OFF, the stack trace is

Uncaught TypeError: Cannot read property 'parentNode' of undefined

Hi,
Ran into the same exact issue today and cannot resolve. Error scenario is straight-forward.

1. Create grid widget that is ‘goupable’.
2. Before grouping perform $(“#grid”).jqxGrid({‘showfilterrow’: true});
3. $(“#grid”).jqxGrid({‘showfilterrow’: false});
4. Try to drag and drop a column to ‘groupby’

Error occurs exactly as described above.

I tried to $(“#grid”).jqxGrid(‘updatebounddata’, ‘filter’) and similar with no luck.

Any other ideas show to reset the grid so that groupby will work again?

Thanks
Rob

Nice! Thank you very much!

Hello Todor,
I tried the fiddle, but that would be a usability nightmare. End-users wouldn’t be happy when having to edit even a few cells as it opens and closes constantly. I guess there’s no way to suppress the close event when editing?

Thanks

Hello,
Your example is fine, however in a bootstrap app that contains other elements the grid is does not refresh leaving half-painted columns. The only way I am able to get the grid to properly repaint is attaching window resize event – i.e.

$(window).resize(function() 
	{
		$('#mygrid').jqxGrid('render');
	});

Even, ‘refresh’ does not work – only ‘render’

Again, seems odd that I would need to monitor window resize event for this.
