How to display wait image while expanding node to display many child records ?

Thanks a lot !
It helped solving my probleem.

The solution above seems not to be working for me. I have already loaded my grid from an xml.
Then I want to expand a certain node where there are a lot of child items inside. I want a loading message/image that will appear until expand node is completed.

I am using dhtmlxtreegrid 1.6 with enterprise license.

If you are using dynamical loading - the both events - “onXLE” and “onXLS” will be generated
If you are using static loading - you can use “onOpenStart” and “onOpenEnd” events, but , because all processing done in same thread in sync. mode, browser will not update view until rendering finished ( so while event  occurs it not possible to show loading message in such case )
