[flexcoders] Expand all items of a tree
Hi, in flex2b3, I could open all nodes of my tree by doing this: treeTest.selectedIndex = 0; treeTest.expandChildrenOf(treeTest.selectedItem, true); Unfortunately, this isnt working anymore. I tried treeTest.expandItem(treeData.node[0],true, false); , teeTest.expandChildrenOf(treeTest.firstVisibleItem), but no luck. Who helps?

RE: [flexcoders] Expand all items of a tree
Its working for me. Heres an
example. Im not sure what you are wanting to do, but in this example you
have to select a tree item, then click the Expand All button. You can modify it
as desired.

RE: [flexcoders] Expand all items of a tree
Yes, I have gotten so far too.
The problem is I want to open the items
directly, without a user clicking on something.
Before I could just set myTree.selectedIndex
to 0, and after that myTree.expandChildrenOf(myTree.selectedItem, true);
But after debugging, I found that if you
set the selectedIndex to 0, it doesnt set the selectedItem, it stays
null until a user clicks on a node.
I should be able to trigger it without
doing that, but I cant find it
Help! :-)

Re: [flexcoders] Expand all items of a tree
Seems to work for me. If you change the code for expand() in Martine's example to : private function expand():void { myTree.selectedIndex = 0; myTree.expandChildrenOf(myTree.selectedItem
, true); }It works without clicking on the tree first...-- davidMany people die at twenty five and aren't buried until they are seventy five. - Benjamin Franklin
