Thanks Tony.

I must admit, I overlooked this optional id you can set when creating these buttons.

(just for future reference, like this:

.jqGrid(“navButtonAdd”,”#tree_pager”,{

ah, I see.

I'm using JSON, and my data is like this:

{"total":"1","rows":[{"level":"0","isLeaf":"false","expanded":"false","description":" group description" ,"name":"groupname01","parent":"null","id":"groupname01"},{"level":"1","isLeaf":"true","expanded":"true" ,"name":"name02","parent":"groupname01","id":"name02"} ....

So the level is sent first.

I don't have “info” in my JSON, this is an extra column in the view, that I map to the name (with jsonmap:”name”) because i need that to construct the url.

So I think i have everything for option 2, or do i need to do something else? I'm not sure I understand “named conventions”, do you mean i need to explicitly define in my jsonReader to use “level”?

Thanks already,

Stefan
