Hi Oleg,
Even I have the similar problem. I am using local data. In my case…When I click on expand/collapse icon, first I need to send a request to server, then refresh treegrid dataset with the server's response and then call treeGrid's expandRow.
How can I call a method(I mean override treeGrid's expandRow method) which does the abve things before calling treeGrid's expandRow method?
Thanks in advance,
Chaitu
