TreeGrid dynamic load of children

[jbambroughParticipant]

Hello all,

We have a tree grid set up 3 levels deep, set up as a hierarchy. There is a massive amount of data (over 10,000 rows total) so for the sake of conserving bandwidth and performance, we want to set it up so that ONLY the top level entries will get pulled back initially – then when a user drills down into one of those parent entries, at this point there would be an ‘on-demand’ request to the server to pull back the related level 2 entries; then the same thing for level 3. So the data will be truly dynamic requests upon drill-down (vs. loading up all 10,000 rows initially). Is this possible? If so, how do we set this up?

Thanks,
-Jim

Hi Jim,

I would suggest you to look at the widget’s examples. It’s shown there how to implement loading of records on demand. Also make sure to turn on Paging for such amount of data.

Ok, thanks Peter – I will revisit this; in that example does this truly load the data on demand? One of my developers was under the impression that the all of the data needed to get loaded upon initialization. If so, then I think this will be a good solution for us

Hi jbambrough,

In this example: http://www.jqwidgets.com/jquery-widgets-demo/demos/jqxtreegrid/javascript-tree-grid-load-on-demand.htm?arctic and in this one: http://www.jqwidgets.com/jquery-widgets-demo/demos/jqxtreegrid/javascript-tree-grid-virtual-mode.htm?arctic, data is loaded on demand. Examples are Virtual Mode with Ajax and Virtual Mode.
