HI Manikandan thanks for replying
i tried this
mx_internal
*function* expandItemHandler(event:TreeEvent):*void*
* *
{
*if* (event.isDefaultPrevented())
*return*;
*if* (event.type == *TreeEvent*.ITEM_OPENING)
{
expandItem(event.item, event.opening, event.animate, event.dispatchEvent,
event.triggerEvent);
this.ValidateNow()
}
}
But still if i manually collpase the branch scroll bar jumps back to top.
