in my application I have used advancedDatagrid and
hierarchicalData as davaprovider. When i exapand a node i need that
if any other node is expanded, it should collapse. I have done
googling for that but could not find any solution.
We can collapse all nodes at once by collapseAll(), but there
do not seems any option so that if any node is exapanded at any
time all other nodes which are expanded should get collapse at that
If any one know solution n hv any idea plz reply...
