Deleting nodes in tree structure
Hi All,
I have created a classical tree strcuture. Now I need to implement a delete functionality. This should delete all the nodes that are selected. If the node is a parent node, then, when I press the delete button, I should find both the parent and the child nodes deleted. How do I build a logic for this. Any help
you can read the table node_table with nody key value which imports when docubble click the the tree node (Double clifk event).

Gopi .

Help on Deleting Node in Tree?
I'm trying to delete a node on a tree and some weird stuff is
occurring. Here is my code:
<?xml version="1.0" encoding="utf-8"?>

<mx:Button click="click();" x="141" y="557" label="Delete
Selected Node"/>
</mx:Application>
For some reason when I expand all the nodes and try to delete
one of the great grand children all of the great grand children
shift over as if they are siblings of the node that I deleted the
great grand children from.
Anyone have some good ideas? I sure wish deletion of nodes
was as easy as in actionscript 2.0There a quite a few posts about this problem here already -
it seems to be a tree rendering bug (seems to come in various
different flavours).
The safest work around after fiddling with the nodes in the
tree is to get the axe out and reassign the data provider. To be
nice to the user, you might want to keep the expansion state (this
may not work if you made big "structural" changes to the tree).
The following works for me (after your changed the tree data
model):
var openItems:Object = treeopenItems;
tree.dataProvider = tree.dataProvider;
this.openItems = openItems;
Hope this helps.

How can i add and delete node in tree in run time
i want to know the method that let me select tree node to delete it and another to input upon user inputs
Hello,
why don't you just enter "add tree node" in the Search Forum search box ?
There are plenty of samples.

Adding Node and Deleting Node in Tree
Hi,
I am building a tree dynamically.
I have a class which has set of properties.I am constructing as follows.
public class TreeNode
public function TreeNode()
public var friendlyName:String;
public var icon:Class;
[Bindable]
public var children : Array;
public var logicalName:String;
public var neType:String;
[Bindable]
public var arrayColl:ArrayCollection = new ArrayCollection();
public function addChild(node:TopoTreeNode):void
if (this.children == null){
this.children = new Array();
children.push(node);
arrayColl.source = children;
public function clearChild():void
children = null;
public function removeChild(arrayIndex:int):void
if(children != null)
children.splice(arrayIndex,1);
arrayColl.source = children;
Then I set the dataProvider as follows where treeModel is object that is injected.
<mx:Tree id="tree"
dataProvider="{treeModel.rootNode.arrayColl}"
labelFunction="{treeModel.getDisplayName}"
iconFunction="{treeModel.setIcon}"
width="100%"
height="95%"
rowCount="6"
showScrollTips="true" showDataTips="true" dataTipFunction="{treeModel.getDisplayName}" allowMultipleSelection="true" click="treeModel.displayItemInWorkingView(tree.selectedItems);"/>
TreeModel has the following variables
[Bindable]
public var rootNode:TopoTreeNode = new TopoTreeNode(); // this is the rootNode.
[Bindable]
public var rootChild:TopoTreeNode = new TopoTreeNode(); // this is the child of the root node..
While constructing the tree, it is working fine.
But after this when i try to add a node (ie adding a node as child to rootNode), it is getting added to my rootNode object but it is not getting displayed
When i click on the items in the tree or click on the drop menu in the tree it is getting displayed.
But i want it to be shown in the tree without clicking anything.
Could anyone help on this?
Regards
SriniOff the top of my head, you need to call a refresh of some sort, or executeBindings()... something like that.
You will also need to start at the root node and expand any parent branches down to the new leaf.
If you are still having trouble after looking into that, I can try and dig through some of old code and find my solution. -
Program to add node / delete node in the tree control via abap object
Hi all,
i am new to abap objects.
Can anyone help me out to give program about add node , delete node at
a particular point in tree hierarchy.
folder1 -- level 1
subfolder1 -- level 2
*********subfolder1 -- level 3
*********subfolder2 -- level 3
subfolder2 -- level 2
folder2 -- level 1
if i select level3 and click on ADD button .....i get a facility to add new node
at level 3 and and same thing can happen at level1 and level2 ............ if i select
and folder at level3 and click on delete button ....it should delete that folder...
if you do not have such program ........then guide me how to achieve this target via object oriented because i have to split the screen also and have to show some alve display in that.
just guide me how to add and delete node at a particular level in tree structure....
thanks in advance........Hello Ravi,
Try this demo program:

To change Font of a Particular Node in a tree structure
IS there any way to set Visual attribute property to a particular node_lable on Heirachical tree Structure.
e.g.
Main Office has Two Branch Offices(Office1 and Office2). and Office1 has Three Sub Branches(sub1,sub2 and sub3).If I am working from Office1, and I want to print Organisation Structure with Office1 with font_weight as Bold.Enhancements IF applied they will be available only in new releases of Forms, which probably be 11i. It's not possible to have it in Forms 6i.
Froms 6i it's already out of support (has minimum support I think).

How to get the folder name of selected subitem in tree structure?
Hi All,
I created a tree structure like below.
->Folder1-- 1
2
3
->Folder2-----1
2
3
i.e i have two folders & each folder having the values like above.Now i want to perform some action by clicking on the any of the values.Suppose if i click value 2,i want to do some action.the actions need to perform is varies from floder to to folder.
So How can i get the folder name of clicked Value?
Regards,
RaviHi Kumar ,
the below code should help you.
Register the below action for the leaf node for which u need the subfolder's name above it.
Worked fine in my system ...hope it does in ur scenario too
method ONACTIONGET_PATH .
data : lr_element TYPE REF TO if_wd_context_element,
lr_node TYPE REF TO if_wd_context_node,
ls_path type string,
ls_path_node TYPE string,
lt_string type TABLE OF string,
l_lines type i,
l_lines_1 TYPE i.
lr_element = wdevent->get_context_element( 'CONTEXT_ELEMENT' ).
**-> getting the path of the node/leaf
*which u had clicked and from that getting the node above it
ls_path = lr_element->get_path( ).
SPLIT ls_path at '.' into table lt_string.
-> remove the first 2 entries as they will contain the view name
DELETE lt_string FROM 1 to 2.
l_lines = LINES( lt_String ).
l_lines_1 = l_lines - 1.
-> remove the last 2 entries as they will contain the element in the path
DELETE lt_string from l_lines_1 to l_lines.
LOOP AT lt_string into ls_path.
CONCATENATE LINES OF LT_STRING into ls_path_node SEPARATED BY '.'.
ENDLOOP.
**-> getting access to the node above the leaf element
LR_NODE = WD_CONTEXT->PATH_GET_NODE( path = ls_path_node ).
lr_element = lr_node->get_element( ).
**-> Getting the name of the folder...
*here path is the attribute in my context which stores the name of the folder
lr_element->get_attribute( EXPORTING name = 'PATH' IMPORTING value = ls_path ).

How to populate Tree structure from BAPI while tree grows or shrinks
Hi All
Currently I am populating the tree structure from BAPI based on the HLevel (Hierarchy Level) parameter, but when ever insertion and deletion happens in the tree at any level in the UI and at the same time i am updating these tree node values with HLevel value(example : 1 is first level , 2 is second level, 3 is third level etc) updating successfully& correctly into the BAPI, no issues.
Once it is updated into the BAPI, next time when i refreshed the UI then i am not populating the tree structure correctly from BAPI with updated new nodes based on the HLevel. when tree struture grows or shrinks in the BAPI after updating into BAPI from UI then i am not populating the tree sturcture correctly based on the HLevel value from the BAPI.
Please let me know any sample code how to populate tree structure correctly when tree structure grows or shrinks based on the HLevel value ( Hierarchy Level , for example : 1 is level , 2 is 2nd level , 3 is third level nodes etc)
anybody helps in this regard with sample code on the populating tree tructure then it would be great help to me.
Thanks in advance

Hi experts,
can any one give me sample code for providing tree structure in f4help. like object part field have in iw21 transaction
Regards
reddyHi Muttukundu,
SAP has provided a lot of sample programs for developing tree structures. Just go to SE38, type BCALVTREE and hit F4. You'll get different sample programs with a range of operations on trees
Go through the link,
http://www.sapdevelopment.co.uk/reporting/alv/alvtree.htm
Slowly check this code..you will get idea of how to develop tree structure.

Refresh functionality of a tree structure......
Hi Friends,
In my application i have a Tree structure and when i click on the root node i get the sub-elements under this and when i select an element and execute this element gets deleted/removed.
Now the problem is such that the element is getting deleted in the backend(R/3),but i am able to see the element in the structure still.
When i click on Refresh icon i cannot view the element.
I have tried to used invalidate method,reset method but still the problem remains the same.
Is there any solution to refresh the application manually without clicking on Refresh.
Please help me out to proceed further.
Thanks and regards,
Chandrashekar.go to view properties and set Life span as when_visible.
or each time you need to call the RFC execute method whenever you delete or change tree elements

Tree structure automation via the tool
Hi All,
We test a tool called as Service Implementation Workbench (SIW). We have started to automate this tool and we are facing few issues while recording the u2018Tree Structureu2019 in the transaction u2018SIWu2019. eCatt is not able to recognize the sub nodes within the main nodes in the tree structure that we record, and the recorded script fails when a new node is created or deleted manually from the tree structure after the recording of the script.
example i have a node say kanchan within this node i have sub node implementation
then again say i have another node ZSIW with in this node i have sub node again implementation
so during recording i am able to locate the main node but it fails to locate the sub node implementation as soon as i add any node manually in the project the script fails.
Can anybody helpHello,
Let me know which driver are you using for recording of the Tree structure, are you using TCD then TCD doesnt recognize the tress structure well, instead use SAPGUI.
If your problem is that since the position of the subnode changes when you add some more parent nodes then the recording should be like clicking on the find button then search for the sub node by entering its name and then you do the procedure required.
Thanks,
