Browser crashes with huge data

[vankin09Participant]

Hi,

I have a treegrid with virtualMode. On expanding a node, a call is made to server to fetch the required data.
I have noticed that when the data size is huge (10000), the browser crashes at the following statement :

callback({
	records : objects
});

Please let me know if there is a workaround which I can.

Regards,
Rajesh

Hi Rajesh,

If you load 10 000 records when you expand a records, then you should expect that it would take time while the data is loaded. Also, for large data sets, turn on paging.

Hi Peter,

I don’t mind the time, but the browser itself crashes.
The load on the browser becomes too much.
Our requires us to show a hierarchy in a single page, so that the user knows the hierarchy he’s operating with.

Is there a way to dynamically load the objects only on scroll action or some kind of lazy loading, such that I won’t have to load all the 10000 records at one shot. ?
Anyways the user will be able to see a max of 20-50 records at any single point of time(without scrolling).

Regards,
Rajesh

Hi Rajesh,

jqxTreeGrid supports lazy loading which is demonstrated in several demos on our jqxTreeGrid Demos page. Example with more than 10 000 records: http://www.jqwidgets.com/jquery-widgets-demo/demos/jqxtreegrid/javascript-tree-grid-virtual-mode.htm?arctic. The jQuery TreeGrid widget loads the data in less than 1 second. I would suggest you to follow that approach in your scenario.
