Hi jqwidgetsdev,
this feature isn’t officially supported for multiple reasons. One of them is because an error might be thrown when you initiate an update operation before another one has completed (due to asynchronicity). Although it could be possible to make it work if you are wiling to try. You should be able to load the data that you receive to a dataAdapter and then load it as a source to the treegrid or save the received data to a local file and add the data to the treegrid(addRow) and then refresh it. Overall it’s not a good idea to load streamed data to a treegrid, because there’s no way of knowing when and what updated, not to menton that this will seriously affect the operation of the widget.
Best Regards,
