I'm trying to get the Treegrid to automaticly expand the last open node after reloading the data. However I can't seem to get it to work, the expandNode function doesn't open the row.

My code:

$('#grid').expandNode($('#grid').getInd(lastClickedRow));

lastClickedRow is the rowId of the row I want to open. This function does something (the grid reloads), but it doesn't expand the rows. We load all the data at once, so the should be no need to reload the grid (when clicking in the grid on the + it opens fine, without reloading the grid)

What am I doing wrong, any ideas?
