Re: [flexcoders] Event to detect data was loaded in a tree
Hello,
what worked for me was this:
_tree.addEventListener(FlexEvent.UPDATE_COMPLETE, _treeDataChanged);_tree.dataProvider = _data_xml;
private function _treeDataChanged(e:FlexEvent):void{
//remove the listener so the user canopen and close items _tree.removeEventListener(FlexEvent.UPDATE_COMPLETE, _treeDataChanged); _tree.expandChildrenOf(_tree.firstVisibleItem, true);};

RE: [flexcoders] Event to detect data was loaded in a tree
Footree.dataProvider would be a good
place. Im not sure if it will fire events as you expand nodes, but its
my best guess. Adding onto myDP would let you know when the actual source data
is loaded from the server for example.

so if I have mx:Tree id=footree
dataprovider={ myDP } .
Where do I add the event listener for this CollectionEvent.CHANGE?
to the tree itself? Or to footree.dataProvider? Or to myDP
some how?

Hi,
I have run into this issue before and I swear I couldn't find an answer for it.
There are many events you can listen for for a Tree changing it's state and
data changing.
But... As far as granular control dealing with when particular nodes are loaded
AND rendered is a completely different issue.
I am writing a CheckBoxTree component right now and have got into the
dataDescriptor and dataProvider algorithms heavily. This is tempting me to
create another type of tree that would give you control with such features.
The tree is a very powerful component, it's just that there are so many
directions you can take with it that it's no wonder Adobe hasn't had time to
get to stuff like this.
Adobe, Is there a way to do this, if I am wrong it would be a welcome correction.
Peace, Mike

looked all through the docs, but I can't find a data loaded event.
Please point me in the right direction!

Re: [flexcoders] Event to detect data was loaded in a tree
footree.dataProvider? Yeah,This still doesn't solve some precise loading scenarios though. This just means it changed somewhere, you can get locations of indexes BUT finding out when that particular node is rendered is what needs to be implemented.
