Flex tree control expanditem dynamically..?

Hi All.,
 I have using tree control using to display. when i pass the data with folder id dynamically to expanding particular child node of tree.
 How to extarct tree with dynamic...?
Below sample coding.....
<mx:tree id="folderTree" />
folderid=2618;
 callLater(expandTree, [folderid]);
 private function expandTree(folderid: Object) : void
 folderTree.expandChildrenOf(folderTree.getChildAt(0), true);
 folderTree.selectedItem = folderid;
but not extracting tree.
anyone help this problem
With Regards.,

Thanks buddy for the answer.
Unfortunately the answer came after quite long time of posting the message. Anyway I was able to open a tree on demand using HttpService and due to my new requirement I changed it to RemoteObject.
I my latest change I am able to populate tree nodes on demand and also the same solution if getting update from server via JMS using Consumer object.
I kind a like this solution because it took me good amount of effort to find the right solution.
If any one is intersted the he/she can reply to the post and I can provide code here or may at some location so that it can be easily downloaded.
The solution is Flex-Grails combination.
Thanks everybody.

How to Flex tree control using folder click event to pass coldfusion to get data from dynamiclly ?

Hi friends.........
Iam using flex tree control data coming from coldfusion file to display grid. As i click the tree folder to change the data from dynamic from grid.
How to pass the folder id from coldfusion file.. Is it possible ?.. Means give any example please....
Any One Help Me......
With Regards.,
Lingu.......

When you set the dataProvider for your tree control, you actually pass an array or arraycollection or whatever to that property. The array contains objects coming from your server, right? Each object should contain a property with the folder id, something like:
var arr:Array = [{id: 1, folderID: 34, name: "..."}, {id: 2, folderID: 4, name: "..."}, ...];
Now, when you click an item in your tree or your dataGrid, you can access the folder id by:
myTree.selectedItem.folderID
Hope this helps

Populate flex tree control on demand using HTTPService (Flex 3)

First, I am sorry if the same post is already posted here but after spending 30 minutes or may be more I could not find the solution.
By the way I have two problems. 1.) I am new to flex which I know if my own problem and soon I will handle it.
2.) This is major problem for me. I have to populate Tree control from database and I used HTTPService to get the data from database.
I created a object of HTTPService and on load of Tree control I am calling a function which calls the HTTP URL and returns me the first level of node for my Tree.
When I click on any node a function is called again using HTTPService and result is appended to the currently selected node. The same goes until n level and it works fine. I was happy with my results. I am stuck in new problem. The problem is if the tree is already populated on my browser and I make some add/update/delete any node or child node, the flex doesn't make a call to HTTP URL and I am not getting updated data.
The mxml code is below (this code has some extra things too).

Populate Flex tree control from mysql

Hi
I am just learning Flex and I started playing with the Tree
control. I am trying to populate the Tree from Mysql using php and

If you are aware of a clear example of how to use the data

enlighten me. Meanwhile I continue my search but not within the

Change the root of Flex Tree dynamically

I have a Flex Tree constructed dynamically. The dataprovider is xmllistcollection.The user clciks on a button to add an item(node) to the tree.
when user tries to add 2nd item to the tree I want to create root(with a button) at the top automatically.
So a Root need to be created dynamically after 2nd item is added.
Can someone please help me in getting this.
I am using MXTreeItemrender as Itemrender and was able to add nodes. But I could not get the third item(I am taking this xml node as Branch and adding) added to the top of the tree.
Any help is very much appreciated

Or in APEX 4.0 this can be done using a Dynamic Action that executes JavaScript code to change the region title.
Give the region a static region ID for use in a jQuery selector.
As solutions may be dependent on APEX version—among other factors—always specify the following information in your initial post:
<li>APEX version
<li>DB version and edition
<li>Web server architecture (EPG, OHS or APEX listener)
<li>Browser(s) used
<li>Theme
<li>Templates

Flex Using Tree Control in item renderer(Url Navigate)?

HI All.,
Iam Using flex 3 using tree control in item renderer to click haschildren label to be navigate url is possible ?.
Any one help me.....

You can do this by writing the item's tag to the ActiveItemTag property, the column number you're intersted in to the ActiveColNum property and reading the Cell String Property.

Report with Dynamic tree control

I have a report with a TREE CONTROL.

A Tree is referenced to: CL_GUI_ALV_TREE_SIMPLE and is located on the left side of the screen.

See diagram below. The Tree has MULTI-LEVEL nodes and the user can click on any of the nodes which will
trigger a report (rellevant for that node) to appear in the REPORT container.

Everythign is working fine.

I now have a requirement to add a TREE ON/OFF functionality. I have added this by 'Freeing' TREE
container and by initializing when the user Turns ON the TREE. It is working fine, HOWEVER, when
it initilizes the TREE it is COLLAPSED and obviously does not point to the NODE that was clicked.

My goal is to retain the value of the NODE that was pressed and EXPAND the tree to that node and
highlight it... Please note that I have MULTI-LEVEL nodes and the user can double click on NODES
and ITEMS.

I tried using GET_SELECTED_NODES, but it only works if the user selects the LOWEST level node/item.

Any advise will be appreciated.

Also, as an alternative, I was thinking of resizing TREE container to WIDTH of 1 when the user PRESSES
TREE OFF and resizing back to width 200 when the user presses TREE ON. I could not find any methods
that would work with CL_GUI_DOCKING_CONTAINER.
Please help! Thank you in advance.

Items in Tree control move around when data is submitted using custom ItemRenderer

I'm working on a Tree control with an XMLListCollection as
its dataProvider.
The dataProvider has information looking like this :
quote:
<?xml version='1.0' encoding='utf-8'?>
<INFO>
<FIELD label="STR_USER_NAME"
type="text"
value=""
>
</FIELD>
<FIELD label="STR_USER_EMAIL"
type="text"
value=""
>
</FIELD>
<FIELD label="STR_OPTIONAL"
type="branch"
value="0"
>
<FIELD label="STR_USER_ADDRESS"
type="text"
value=""
>
</FIELD>
<FIELD label="STR_USER_POSTAL_CODE"
type="text"
value=""
>
</FIELD>
</FIELD>
</INFO>
So in the Tree control I'd like the information to show up
with a label and
an
editable textbox for each item :
[Label] [textbox]
To do this I made a tree like this :
quote:
<mx:Tree id="userTree"
editable="true"
rendererIsEditor="true"
editorDataField="curVal"
itemRenderer="{new ClassFactory(ItemRendererUser)}"
itemEditEnd="e_ProcessData(event);"
dataDescriptor="{new DataDescriptorUsers()}"
showRoot="false"
verticalScrollPolicy="{ScrollPolicy.AUTO}"
/>
where the e_ProcessData() function looks like this (I used
http://livedocs.adobe.com/flex/201/html/wwhelp/wwhimpl/js/html/wwhelp.htm?href=c
elleditor_073_16.html#202105 as a guide) :
quote:
public function e_ProcessData(event:ListEvent):void
event.preventDefault();
userTree.editedItemRenderer.data.@value =
ItemRendererUsers(event.currentTarget.itemEditorInstance).curVal;
userTree.destroyItemEditor();
userTree.dataProvider.notifyItemUpdate(userTree.editedItemRenderer);
} // END OF e_ProcessData()
I attached the rest of the files because they're a little
bit longer.
When I run the program, the data shows up fine when it is
initialized the
very
first time, and I made a test button that just dumps the
contents of the
dataProvider in a trace statement to verify that the data has
been set
properly.
The problem I've run into is whenever the textfield is
edited, the item
that
I've selected jumps around the list.
For example, if I edit the item "STR_USER_NAME" after I
finish the edit, it
will move from the very first position in the Tree to the
bottom of the
Tree.
I traced the contents of the dataProvider and the
dataProvider structure
stays
the same, with the "STR_USER_NAME" at the top, but if I look
at the flex app
in
the web browser, its position is at the bottom of the Tree.
This happens for every other item I try to edit... I read in
the
documentation
that the ItemRenderers are recycled, so it means I should be
checking to
make
sure the initial states are covered, but I'm not sure how
this affects my
application.
Can anyone help me out with this ? Its very confusing - I've
tried making
an
ItemRenderer using pure actionscript, mxml and the
combination you see in
this
example and I always end up with the same behaviour - So I
must be missing
something critical...
// ItemRendererUsers.mxml
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="
http://www.adobe.com/2006/mxml"
verticalScrollPolicy="{ScrollPolicy.OFF}"
horizontalScrollPolicy="{ScrollPolicy.OFF}"
creationComplete="initItemRendererUsers();"
>
From my FAQ:
Q: I've created a custom itemRenderer component to use in a
List
based component (Datagrid, TileList, HorizontalList, etc.).
When my List
first displays, everything looks fine, but when I scroll it
or change the
dataProvider, some of the itemRenderers show values or
formatting that
aren't right. How do I fix this?
A: List-based components don't draw a renderer for every item
in the
dataProvider. Instead, they create enough to display what is
on screen now,
plus one or two more waiting in the wings. This means they
recycle the
renderers rather than creating new ones when you change
dataProvider or
scroll up and down. When you use a creationComplete event to
set up the
itemRenderer, that event doesn't happen again when the
renderer is used for
a different set of data. The solution to this is to override
the set data
protected function that most components have.

Your set data needs to set a flag that gets picked up in
commitProperties()
and does your thing that you were doing before in
creationComplete. You
should see examples of this in the links I posted. Instead of
this:
_data.@value = inputText.text;
you should look at implementing IDropInListItemRenderer,
which will allow
you to dynamically determine which field to look at, instead
of hardcoding
it. You also might wind up overwriting the stored value with
a null value
when the List passes the stored value in. I'd encourage you
to really go
through those links I posted and make sure you understand
what they're
saying. The itemRenderer life cycle is one of the hardest
things to
understand, but once you understand it, it makes many things
in Flex much
easier. It's worth investing the time.

Not able to get the database data into the Tree Control

Hi Everybody,
I have to populate the tree control with nodes and items, which is to be populated from the database, and the tree control is dynamic. I mean, there is a toolbar, whenever a pushbutton is clicked, depending on that the tree contents has to be changed.
If anybody had worked with CL_GUI_COLUMN_TREE control to get the data from database, depending upon the pushbutton selected in Toolbar, please paste the seudocode for it.

'If we double click on Node Text it is displaying nothing means no Event is triggering.
