I have a load-on-demand tree (i.e. most nodes have node.ExpandMode = TreeNodeExpandMode.ServerSideCallBack).  In the Page_Load method how can I determine if the postback was caused by a node expand event?

Hi Dave,

You can check first whether it's callback and then the id of the treeview like this:

if(Page.IsCallBack)
{
  String callBackId = Request.Form["__CALLBACKID"].ToString();
}

All the best,
