                        </ext:Store>

Problems:
I want to load all items in Expanded in RowExpander1 in FileGrid. when i am using

 <Listeners><ViewReady Handler="#{FileGrid}.getRowExpander().expandAll();" ></ViewReady></Listeners>

in FileGrid its working but oerrided (dont know which event(listner)) so it is seen like collapsed mode.

when i am using

 <Listeners><ViewReady Handler="#{FileGrid}.getRowExpander().expandAll();" Delay="1000"></ViewReady></Listeners>

in Store its working fine. but i have to give 1000 ml sec. i dont want to give any specific time.

can anyone suggest me any listner event which is last event (counting Store + GridPanel both) that give assurity of ready. So there i can write

#{FileGrid}.getRowExpander().expandAll();

Thanks in advance

Hi @aditya,

The ViewReady listener without Delay appears to be working in this example. Please provide your full test case.
