treeview expand client-side attributes

[csabadapp]

i have a treeview
(id="trv")

i would like to do something like this:
trv.Attributes.Add("onexpand", "javascript:alert(this);");

i cannot make this work
i would like to know if this is the way I should do it, or should i
add some event somehow to each node

basically i would like to do some javascript action on each expand -
each (expanded) node
(later on collapse too)

i found this example in articles like this one:
http://p2p.wrox.com/topic.asp?TOPIC_ID=46824

thanks

[Swoosh]

still me

basically i have somthing like this:

nodeSection.NavigateUrl = "javascript:showMenu('Section', " +
rowSection["ContractSectionId"].ToString() + ", " +
rowSection.GetChildRows("SectionToGroup").Length.T oString() + ");";

i would like to add an other feature like this, only this time i'd
like to do it on expand / collapse ...

thanks again
