I'm trying to make a Flex Tree Component display the children of a sprite in a hierarchical way. Moreover, dragging the items on the FlexTree would resort and reparent the items. I have special Elements set as Folders. This would allow other elements to be added there as a children by dragging an element on the tree and dropping it there. I have a failed attempt which works, but breaks when I try to add folders. Basically, it fails at reparenting the items by dragging and resorting folders and that Does anyone know of a component or something which can do this, has anyone have created any of this or could anyone give me a clue?

View 5 RepliesI've got a couple trees that I allow a user to drag and drop from one to another, works great except one apparent limitation. I'm picking up where they drop it in the list and adding it to the dataProvider manually. The user can drop it everywhere except after the last child of any particular node it seems, since it reads that position as being between the node and it's next sibling.
It seems the best way to deal with this is to add something like a dummy leaf so the user has something to drop the item in front of. I don't want this leaf in the dataProvider, so is it possible to add a leaf (or a folder) to the tree without adding it to the dataProvider?

I have inherited a Flex air project and have not worked with trees before. The tree is displaying an xml file hierarchically. The user can make a change to the data. I need to save the data of the entire tree to a file.I can save the currently selected item to a file, no problem. But I need to save all the data from the root of the tree, forward.I would think I could make a copy of the tree, and set the selected item of my new tree to root, or something. Sort of like this pseudo code:
var treeToSave:Tree = new Tree (editedTree);
treeToSave.selectedIndex = 0;
// now save treeToSave to file...
This creates a compile error, but hopefully you can see what I'm trying to do.

I'm using Flex 3.3.
The tree should have a minimum row count of 4 and a maximum of 10 (beyond which it should display the scroll bars). So, I have a tree with rowCount="4" and I want rowCount to change up to "10" depending on the currently expanded nodes. In debug I can see two of the tree's properties which I could use[code]...
But these are not accessible from outside so I can't find a way to understand if the tree is expanded or not.

i have a Flex tree control and im trying to select a tree node 3 levels down right after the dataProvider is assigned with a collection object like the following.basically treeItem1, treeItem2, treeItem3 are the nodes in the tree and treeitem3 is a child of treeItem2 which is a child of treeItem1. Assume these treeItem(1,2,3) are referenced correctly from the collection items.
my problem is that if i wait for the whole component to load completely then select the nodes, it open/select/scrolltoIndex correctly. However, if i were to select the node right after the dataProvider is assigned, then it doesn't even open or select (basically the this.treeService.selectedItem is always null).
this.treeService.dataProvider = oPricingHelper.getCurrentPricingSercicesTreeSource();
this.treeService.expandItem(treeItem1, true);
this.treeService.expandItem(treeItem2, true);
this.treeService.selectedItem = treeItem3;
this.treeService.scrollToIndex(this.treeService.selectedIndex);

View 1 RepliesI am working on a tree component and I am having a bit of the issue with populating the data-provider for this tree.The data that I get back from my database is a simple array of value objects. Each value object has 2 properties. ObjectID and ParentID. For parents the ParentID is null and for children the ParentID is the ObjectID of the parent.
Essentially the tree should look something like this:
Parent1
Child1
Child1

I have created a custom item renderer for the tree, i have added some children in create children function, my problem is that sometimes i need to show these children and sometimes i don't, depending on clicking on a button which also i have added at create children, the problem is that i had to create the item even if i don't want it to be visible, and removed it by making visible false, and this costs a lot of memory, i have tried to create it at buttons click listener but when scrolling the child disappears, and it may appear again if i keep scrolling up and down.. i am trying to add the child just when i need it to be visible, is this possible or i have to create it on child creation method?
