I need to be able to get a list of rows (client side) that have been expanded, so that when a user reloads the page, I can then expand them.

I've seen code to get the expanded rows, but trying to expand them again, doesn't seem to work. I'm missing something obvious I'm sure.

This is the code that I found (on the forum) to get all the expanded rows:

 arrExpandedRows = $("#gridRRA").igHierarchicalGrid("allChildren");

This is what I was using to expand the rows (found in the forum):

for (i = 0; i < arrExpandedRows.length; i++){
var rowDom = $("#" + arrExpandedRows[i].id);
$("#gridRRA").igHierarchicalGrid("expand",rowDom);
}
