Hello,
at the moment the only way to achieve an auto expanding on treegrid load is to do it by hand. The documentation states that it is planned to provide a method called "expandAll"/"collapseAll"... @Tony: can you tell me, if this will be implemented in releases in the nearby future?

Hello Marcel,
collapseAll can be done easy, but I have dificulties on how to process with expandAll. The problem : When we use autolading nodes (load nodes with ajax) how we should process with this when we call expandAll? It is not a trivial task.
Best Regards
Tony

Hi Tony,
I'm using the adjacency model with automatic nodes loading (single ajax calls). You're right... it's not trivial due to the fact that a simple solution would cause an inacceptable amount of ajax calls. So the main target would be to circumvent this problem using one single call but getting all desired information.
A first approach could be to let the expandAll() method send all non-expanded node IDs (or sth. appropriate) via POST to the server which in turn will provide the data as a special crafted JSON array applied to every node ID. All further expandAll()/collapseAll() operations could be done on client-side as the data has to be loaded only once.
Dunno if this is consistent to the current jqgrid infrastructure. 
Greetings from Germany.

Hello again,
Thanks for the suggestion. I will consider this approach too, but this require to have another script to load data at once. Will think instead of this.
Best Regards
Tony
