View 1 RepliesFlex :: Add A Node To Tree Without Adding It To DataProvider?
Feb 23, 2010I'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?
Flex :: Select Tree Node Right After The DataProvider Is Been Assigned / Updated / Replace?
Jan 26, 2011i 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);

Flash :: Flex 4.5: Tree - Make A Flex Tree Component Display The Children Of A Sprite In A Hierarchical Way
Nov 19, 2011I'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.

View 1 RepliesActionScript 3.0 :: Setting Up Expanding XML Tree Menu And Linking Button Listeners?
Dec 19, 2011I'm making an application that uses a branching tree type structure, and need to get the buttons to refer to and be able to manipulate individual XML nodes. I tried putting a button reference directly in the XML and setting the reference to that node with the event data, but it didn't work, because the XML didn't recognize the event.currentTarget as an actual button, so couldn't find the node that contained the click target. I assume there is a standard way to do this, since it's so common. Just for clarity, the tree will basically look like this:
PrimaryNode1
Subnode1
Subnode1a
[code]....
I need to be able to keep track of which subnode goes where for determining other data as well as graphically positioning the node and subnode data); PrimaryNode2 etc., with add and expand buttons. I can't set static references, since all of the nodes are added through the program depending on if they're needed. I tried doing this with multidimensional arrays, but since I want each level to be theoretically (but not practically) infinite with infinite subnodes, checking through the arrays got kind of messy. I just figured there has to be a standard way to set this up, since it's so common.

Flex - Add Row To Flex DataGrid Without Changing DataProvider
Sep 30, 2010I am creating the standard "Click to add row" control but I really don't want to dirty the dataProvider with a "placeholder" since it is bound to the model and could end up in the database. Is there a way to add a row that isn't represented in the dataProvider? I started down the road of adding an item directly to listItems but then that needed an item in rowInfo and then that need a reference in rowMap.

Adobe Flex Combobox DataProvider?
Jun 9, 2010I have a project that was compiled with the Flex 3.2 SDK. One of my components is a combobox, which is bound to a property (called products) in the Cairngorm model. If I insert a new value into model.products, then the combobox immediately shows the new value. Works perfectly.
I then moved to the 3.5 SDK, and running the identical operation causes a problem. Even though the model has been updated (I have verified that this is definately the case), the combobox does not show the new value correctly - it seems to be aware that there is a new item because there is a new row in the combo, but the new row is blank and unselectable. The existing items in the combo are there and selectable (as they should be). If I re-initialising the form (i.e. close and re-open the TitleWindow on which the combo is located), then all the correct values (including the new one) are shown in the combo.
I have swapped back and forth a few times between 3.2 and 3.5 to verify that this is indeed the root cause.

I'm getting results in batches of 10, and I need to add each batch to the dataProvider when it's received. I also tried to to do...

Flex :: Cache Variables In Dataprovider?
Jan 5, 2012I've got a model class with a bunch of Number variables that change frequently. They all dispatch their custom events, thus are bindable. In my UI, a couple of those class instances are bundled into an ArrayList that serves as the dataprovider for a Spark DataGrid. The class variables change perfectly fine, so problem there.
What I'd like to do now is to change the color formatting of those numbers (the corresponding labels in the gridcoloums to be exact) depending on the data that comes in, so to say change in green when the new value is bigger, change to red when the new value is smaller than the old one.
