Seaching A Tree Node Value

How Do I search for a Node and highlight it using the Node Label?
I want to start searching from any child level and not the root node.

  • How to get a Tree Node Value when a Tree is Expanded

    My reqiurement is when i Expand a Tree i need the Expanded tree Node Value. For Example Consider Parent as a Root Node of a Tree, and Consider its two Children Child1 and Child2.
    When + Parent Expanded
    I will Get the Output as --Parent
    - Child1
    - Child2
    so As when i expand the Tree i must Get the String Value Parent.

  • Read Selected Tree Node value.  Jdeveloper Jdeveloper 11.1.2.1.0 11.1.2.1.0

    Version: Jdeveloper 11.1.2.1.0
    how to get programmatically tree node value.
    i have tried but cann't read value from selected node.
    please help me.
    here is my application creation steps:
    1. New Application
    2. Fusion Web Application (ADF) Template
    3. Create View Object VOTreeMst
    Query:
         Select Department_Name,Department_Id
         From Departments
    4. Create View Object VOTreeChd
    Query:
         Select Last_Name,Employee_Id,Department_Id
         From Employees
    5. Create View Link VLTreeMstChd
         VOTreeMst.DepartmentId=VOTreeChd.DepartmentId
         And Add to Application Module
    6. Create page page1 in ViewController
         New-->Web Tier-->JSF/Facelets-->Page
         Selected Document Type JSP XML
    7. Drag VOTreeMst1 From Data Controls into page1
    and select Tree-->ADF Tree
    8. ADD java Code into selection Listener
    public void nodeSelect(SelectionEvent selectionEvent) {
    //original selection listener set by ADF
    String adfSelectionListener = "#{bindings.VOTreeMst1.treeModel.makeCurrent}";
    //make sure the default selection listener functionality is preserved.

    i need to get value from "Web Tier->JSF\Facelets->page"
    is there any help please?

    You should try Franks generic selectionListener http://www.oracle.com/technetwork/developer-tools/adf/learnmore/25-generic-tree-selection-listener-169164.pdf. For help on hoe to get the selected tree node data check http://www.oracle.com/technetwork/developer-tools/adf/learnmore/26-get-selected-tree-node-data-169165.pdf

  • Assigning Selected Tree Node Value To An Item

    Hi guys,
    I want to assign selected tree node's value to a page item. This item can be a textbox or a label (display only). How can i do that? I tried to use "Selected Node Page Item" property which is available on Tree Attributes. But I couldn't assign the value without refreshing whole page.
    Do you have any idea?
    Thanks.

    Hi ,
    Thank you that was exactly what I was looking for. I couldn't find how to pass database column to javascript as an input parameter. So thanks for your help. I made a couple of correction :
    1) I put additional ' characters to ('''||"NAME"||''') this part because my field is varchar.
    select case when connect_by_isleaf = 1 then 0
    when level = 1 then 1
    else -1
    end as status,
    level,
    NAME as title,
    null as icon,
    "ID" as value,
    null as tooltip,
    'javascript:setFObjName('''||"NAME"||''')' As link
    from "#OWNER#"."TABLE_NAME"
    start with "PID" is null
    connect by prior "ID" = "PID"
    2) In script I have added ' character before and after page item.
    function setFObjName(pobjName){
    $s('P1_OBJ_NAME', pobjName);
    So it works. Thanks tfor your help.

  • Programmatically getting ADF Tree node value(Version 11.1.2.0.0)

    Hi Forum,
    My Jdeveloper version 11.1.2.0.0
    and i am using Fusion Web Application (ADF) Template.
    In my .jspx page i have added ADF Tree.
    Now i want to get node value from backing bean.
    My java code is

    RichTree tree = (RichTree)evt.getSource();
    TreeModel model = (TreeModel)tree.getValue();
    RowKeySet rowKeySet = evt.getAddedSet();
    Object key = rowKeySet.iterator().next();
    model.setRowKey(key);
    JUCtrlValueBinding nodeBinding = (JUCtrlValueBinding)model.getRowData();
    if(model.getDepth()==1){
    int empid = (Integer)nodeBinding.getAttribute("EmployeeId");
    when i click on second node the following error occured.

  • To get  node value in a tree

    I have a tree with 3 level and it is working fine.. In view mode I need the First child value of the 3rd level with out clicking / Selecting from teh Tree node..
    for eg;
    A -- ist level
    Ap -- 2nd level
    Apple -- 3rd level
    So What I need is that I should get a message 'Apple' While landing teh Form itself without clicking on teh Tree
    Thanks in Advance...

    To my knowledge it is not possible to get the value of a node which is not selected.
    What you have to do is to build up a memory structure similar to your tree, then you can access any node at any time.

  • How to modify a node value in a DOM tree?

    I have following code; it parses a XML file from a file and builds a in-memory DOM tree, but when I tries to modify one of the node value, it keeps telling me: oracle.xml.parser.v2.XMLDOMException: Node cannot be modified. How do I do it?
    // ==================================
    DOMParser theParser = new DOMParser();
    theParser.setValidationMode(false);
    InputStream theInputStream = myApp.class.getResourceAsStream("/test.xml");
    theParser.parse(theInputStream);
    XMLDocument theXMLDoc = theParser.getDocument();
    NodeList theNodeList = theXMLDoc.selectNodes("/root/child");
    for (int i = 0; i < theNodeList.getLength(); i++)
    theNodeList.item(i).setNodeValue("test");
    null

    You're trying to set the node value of an element, which cannot have a node value.
    You need to set the node value of the text-node child of the element instead.
    Or remove the current text-node child and append a new text-node child with the new value.

  • Formatting multiple values in ADF tree node

    JDeveloper 11.1.2.2.0 -- WinXP
    I have an ADF tree component that is bound to a table with two values per node level.
    The results look like:
    Fruit 1234
        -- VineGrown 5678
           -- Grapes 4567
               -- Red 1234
               -- Green 56
    Veggie 4567
       -- Root 45
          -- Carrot 34
          -- Potato 987What I want to be able to do is format the outputText so that it will end up looking more like "Fruit :: Total 1234"
    The issue is that the EL of #{node} displays both the node level value and the number as one item. This is in the facet nodeStamp.
    If I try and get more specific with the EL, I can separate out the Uses number by doing #{node.Uses} but I can't get the node name to still be dynamic for each level.
    My binding options for node are shown as:
    node.Type
    node.GrownLocation
    node.Group
    node.Value
    node.Uses
    Of course setting the first #{node} to any of these more specific values doesn't display at all for the node levels that don't correspond to just that one level.
    Ideally the EL line would look something like:
    <af:outputText value="#{node.name} ::  Total: #{node.Uses}" id="ot3"/>where node.name could be any one of the levels: Type, GrownLocation, Group, etc.
    Is this something that pathStamp would be used for? I couldn't really figure out how pathStamp worked from the docs.
    Thanks for any help. Hopefully this makes some sense.

    You can try something like this:
    <af:column id="c1">
    <af:outputText value="#{node.name} ::  Total: #{node.Uses}" id="ot3" rendered="#{node.name != null}"/>
    <af:outputText value="#{node.Type} ::  Total: #{node.Uses}" id="ot3" rendered="#{node.Type!= null}"/>
    <af:outputText value="#{node.GrownLocation} ::  Total: #{node.Uses}" id="ot3" rendered="#{node.GrownLocation!= null}"/>
    <af:outputText value="#{node.Group} ::  Total: #{node.Uses}" id="ot3" rendered="#{node.Group!= null}"/>
    </af:column>So the rendered property will make sure that the correct node is displayed according to each level.
    Hope this helps.

  • Value of currently selected tree node

    Hi there,
    I'm new to Apex(4.1.1) and i'm having a little problem.
    I got 2 Pages. The frist one consists of a treeregion and a submit button.
    The Second one is a Report.
    I want to create a workflow, that the user selects a treenode and presses submit. Then he'll be redirected to the reportspage,
    wich will show him a report depending on the treenode he selected on the first Page.
    Problem:
    I have no idea how i can read the value of the selected treenode.
    I hope you can help me.
    thanks,
    Frederic

    Hi Frederic,
    To obtain the value of the selected tree node, you can make use of the "Selected Page Node Item" attribute on the Tree Attributes page. Just create an item on your page, and set the "Selected Page Node Item" to that new page item. Then populate that item via the LINK parameter of your tree query. For an example, take a look at the following: http://apex.oracle.com/pls/apex/f?p=36648:6 , where I'm setting my page item P6_SELECTED_NODE to the value of the node selected on the first tree i.e. empno. Your report query would need to reference the "Selected Page Node Item", to ensure that it displays information related to the selected tree node.
    I hope this helps.
    Regards,
    Hilary

  • Click on the searched  hierachical tree node

    Hi,
    when i search the hierarchical tree for a string then all the matching nodes come selected.Then when i click on any of the search result nodes it does not work and otherwise i have to click on a non selected node and then click on the desired node .
    For example i have created a tree for material used for manufacturing purpose.i want to display the related suppliers names in an adjacent grid by clicking on the node in the tree. how can i do that directly after getting the search node.??

  • How to resize a custom tree node like you would a JFrame window?

    Hello,
    I am trying to resize a custom tree node like you would a JFrame window.
    As with a JFrame, when your mouse crosses the Border, the cursor should change and you are able to drag the edge to resize the node.
    However, I am faced with a problem. Border cannot detect this and I dont want to use a mouse motion listener (with a large number of nodes, I fear it will be inefficient, calculating every node's position constantly).

    the node on the tree is only painted on using the
    renderer to do the painting work. A mouse listener
    has to be added to the tree, and when moved over an
    area, you have to determine if you are over the
    border and which direction to update the cursor and
    to know which way to resize when dragged. One of the
    BasicRootPaneUI has some code that can help determine
    that.Thanks for replying. What is your opinion on this alternative idea that I just had?
    I am wondering if it might be easier to have a toggle button in the node that you click when you want to resize the node. Then a mouse-down and dragging the mouse will resize the node. Mouse-up will reset the toggle button, and so will mouse down in an invalid area.
