  • How to  create Tree Structure for given data?

    Hi,
    I have to create a tree structure of Folders and the contents in the Folder.
    I have a XML, it contains data for the tree structure to display. How can I create a tree structure which would look like below
    Parent
       Child
         Supporting Views
            Raw eInfotree Table Views
            Background Calculations
            QC Data Views
         Calculation Views
         Unit Operation Views
            Cell Culture Views
            Purification Views
            MFR Views
         Personal Views
    All the nodes should have folder Icon.
    Please find the XML as
    <?xml version="1.0" encoding="UTF-8"?><Rowsets DateCreated="2007-05-02T07:37:37" EndDate="2007-05-02T16:59:53" StartDate="2007-05-02T16:59:53" Version="11.5.3"><Rowset><Columns><Column Description="" MaxRange="1" MinRange="0" Name="TK" SQLDataType="4" SourceColumn="TK"/><Column Description="" MaxRange="1" MinRange="0" Name="NAME" SQLDataType="1" SourceColumn="NAME"/><Column Description="" MaxRange="1" MinRange="0" Name="TYPE" SQLDataType="1" SourceColumn="TYPE"/><Column Description="" MaxRange="1" MinRange="0" Name="PK" SQLDataType="4" SourceColumn="PK"/></Columns>

    Vishal,
    If you structure your data with two columns, the first being the Node name and the second being the Parent node name (see your information below), the iBrowser applet will make a nice data driven tree with all of the SelectionEvent or navigational capabilities you want.

    <Rowset><Columns><Column Description="" MaxRange="1" MinRange="0" Name="NAME" SQLDataType="1" SourceColumn="NAME"/><Column Description="" MaxRange="1" MinRange="0" Name="PARENT" SQLDataType="1" SourceColumn="PARENT"/></Columns>
    <Row><NAME>Parent</NAME><PARENT></PARENT></Row>

    Hi,
    According to your post, my understanding is that you want to custom action for context menu in "Site Content and Structure" in SharePoint 2010.
    In "SiteManager.aspx", SharePoint use MenuItemTemplate class which represent a control that creates an item in a drop-down menu.
    For example, to create or delete the ECB menu for a list item in
    "Site Content and Structure", we can follow the steps below:
    To add the “My Like” menu, we can add the code below:      
    <SharePoint:MenuItemTemplate
    UseShortId=false
    id="OLListItemLike"
    runat="server"
    Text="My Like"
    ImageUrl="/_layouts/images/DelItem.gif"
    ClientOnClickNavigateUrl="https://www.google.com.hk/"
    />
    To remove the “Delete” menu, we can comment the code below:
    <SharePoint:MenuItemTemplate
    UseShortId=false
    id="OLListItemDelete"
    runat="server"
    Text="<%$Resources:cms,SmtDelete%>"
    ImageUrl="/_layouts/images/DelItem.gif"
    ClientOnClickScript="%SmtObjectDeleteScript%"
    />            
    The result is as below:
    More information:
    MenuItemTemplate Class (Microsoft.SharePoint.WebControls)
    MenuItemTemplate.ClientOnClickScript property (Microsoft.SharePoint.WebControls)

  • Org Chart in tree structure

    Hi Friends,
    How to Create a tree structure  for org. unit in  web dynpro ABAP
    and call the tree in F4 Help of a input box.

    Good advice there guys.
    I myself just finished such an implementation at one of my customers. It took 2 days to complete. I can't give you the solution as the customer retains the immaterial rights for the solution but I thought I would tell you the steps involved to get you on the right track.
    1. Context. Build a context node that on the top level has the orgunit, it's attributes (such as otype, objid, stext, etc) and the recursive node that points to the orgunit node. Inside the orgunit create a node for the position. Inside the node place the attributes for the position (like before) and a recursive node that points to the position node. Finally inside the position node place a node for the person and it's attributes (like before), but no recursion node this time.
    2. Layout: Place a tree element in your view. Inside the tree element insert two node types and one item type. First node is for orgunit, second one is for position. The only item is for the person. You might want to add respective icons, to get nicer UI. Add the load children action for orgunit and position. Depending on what you want to select from the tree, add a select action for either orgunit, position or person.
    3. Code #1: as Chris points out, use RH_STRUC_GET to get the organization tree. I myself used O_S_P. You might want to create a FM that returns all 3 itabs returned by RH_STRUC_GET to the WDA. Create a freely programmed value help as suggested in many threads, it's pretty straight forward. In the WDA utilizing the VH, mark one or more items in the context as freely programmed VH and connect to your implementation.
    4. Code #2: At start up, for example in the WDDOINIT method, create only the root node and call it for example "All organization units". Then create one action that is called when children nodes have to be loaded, one method for figuring out what do when a child is being requested (and what kind of child: orgunit, position or person) and finally a method for actually creating the node.
    5. Code #3: The magic comes from RH_STRUC_GET. Use the STRUC itab at runtime to find the objects at certain levels and to determine their parent(s) and children. The most important values in the STRUC itab in this case are LEVEL, OTYPE, OBJID and PUP.
    Pretty straight forward and the solution is quite nice indeed. I'm sorry if I forgot something, I wrote this without access to the system.

  • Tree Structure Implementation in Java.

    1>
    How should i implement a "Tree Structure" in Java Based application.?How would i map the entries to the database table?how many tables will i require for this implementation.?
    List records<String> = new ArrayList<String>();
    records.add("null");
    records.add("Product");
    records.add("Category");
    records.add("P1");
    records.add("P2");
    records.add("P3");
    records.add("C1");
    records.add("C2");
    records.add("C3");
    so how should i implement a Tree Structure for the above record set.
    //P1,P2,P3 belong to Parent {Product}
    //C1,C2,C3 belong to Parent {Category}
    Sample code provided will be helpful

    How should i implement a "Tree Structure" in Java Based application.?The quotes suggest you don't know what a tree structure is, regardless of the development language. Fix that first (your understanding of what a tree structure is). [url http://en.wikipedia.org/wiki/Tree_structure]Here is probably a good start.
    How would i map the entries to the database table?how many tables will i require for this implementation.?It depends on what your tree structure represents, in particular it depends on whether the leaves and intermediate nodes of the trees have are homogeneous (e.g. have a common interface). There is no general rule.
    I suggest you start by looking in the Java API at all the classes whose names start with 'Tree' (TreeSet and TreeMap are probably the best ones to start with) and read the documentation carefully. Then try to write some code that uses one and come back if/when you have any problems.(sorry Winston) I think this is a very bad advice.
    These classes are particular implementations, respectively of a set (in the mathematical sense) and of a map (associative table), which happen to use a "tree structure" for their internal business. Their API doesn't help building a custom "tree structure" (they may be used that way, but it's certainly not the easiest nor even a particular handy way to build tree structures).
    Maybe their implementation may be a good example of how to build a Tree structure, but they use a particular type of tree (+red-black tree), not a general one. This may or may not be the OP's case, I wouldn't bet on it.
    OP you're welcome to come back with more specific questions and details. Good luck with Java.

    After checking the Javadoc: indeed TreeSet only uses a TreeMap for its implementation, so the only one out of the two which does directly uses a tree structure in its implementation is TreeMap.
    Edited by: jduprez on Oct 16, 2010 2:51 PM
    And, to reiterate, I stand by my claim that TreeMap is not a good example of a general Tree structure: in particular it uses a tree to map keys to values, its main business is the "mapping" part, not the tree as a storage medium. Neither the keys nor the values know anything about their "children".

  • Tree structure like in win explorer?

    Hello everybody,
    I need in my program a structure like the tree structure in the windows explorer. Is is possible to program something like this in LabWindows/CVI 6.0 ?
    The program have to simulate an equipment. The tree is for a better finding of the "events", the equipment can do.
    The last "file" in the tree should I took to some buttons to simulate the event. But this I think is not the problem.
    thx for solving my problem ;-)

    Check AL S's response here for how to do this. CVI 6.0 does not have a native Tree control. This was introduced with CVI 7.0.

    2 GNR 10 9 678
    2 BNR 11 9 456

    Hi,
    Thanks for providing the CREATE TABLE and INSERT statements; that helps a lot.
    You want featureids that meet three criteria:
    (1) there is a GID attribute
    (2) the GID attribute has a GNR child with intvalue=123
    (3) the GID attribute has a BNR child with intvalue=456
    Since you're looking for immediate children, not distant descendants, it's easiest to do this with a non-hierarrchical query that finds one of these criteria, and does EXISTS sub-queries to test for the other two.
    For example:
    WITH aat AS
    ( -- Begin aat: join of attribute and attributetype
         SELECT     a.featureid
         ,     a.id
         ,     a.parentid
         ,     a.intvalue
         ,     t.name
         FROM     attribute     a
         JOIN     attributetype     t     ON     a.atttypeid     = t.id
    ) -- End aat: join of attribute and attributetype
    SELECT DISTINCT     featureid
    FROM     aat     m     -- m for main
    WHERE     name     = 'GID'
    AND     EXISTS     (     -- Begin EXISTS sub-query for GNR=123
              SELECT     NULL
              FROM     aat
              WHERE     parentid     = m.id
              AND     name          = 'GNR'
              AND     intvalue     = 123
              )     -- End EXISTS sub-query for GNR=123
    AND     EXISTS     (     -- Begin EXISTS sub-query for BNR=456
              SELECT     NULL
              FROM     aat
              WHERE     parentid     = m.id
              AND     name          = 'BNR'
              AND     intvalue     = 456
              )     -- End EXISTS sub-query for BNR=456
    ;Alternatively, you could do a three-way self join, and skip the EXISTS sub-queries.
    If you were looking for GNR and BNR descendants, any number of levels below the same GID node, it's easy to modify the query above. Just re-write the EXISTS sub-queries to CONNECT BY queries that "START WITH parentid = m.id".
    It looks like this application will have a lot of use for a view like aat, above. If you don't already have a permanent view like that, you should create one.

  • WDA:  Tree structure in web dynpro for ABAP

    Hi,
    I am trying to build a tree structure with information something like the following:
    Country
    State
    City
    I used the UI Element "Tree" and I was successful in building it. The only problem is that it supports only one column in each row like name.
    I need multiple columns in each row like Name and population.
    1) Is there any solution for this using UI element "Tree" only?
    2)I checked that there is Table tree UI element, but I could not figure out how I could use it for hierarchial structure like that of my requirement? Can I use it? Is there any example application with hierarchial structure?
    3)For tree UI element, any node that is not directly below context node has to be non-singleton. It will lead to adverse performance. Is there any solution for this?
    Thanks in advance.
    Regards,
    Srini.

    Hi Srinivasa,
    In the context, please create a node DATA with the following fields:
    KEY type string
    PARENT type string
    LOCATION type string
    POPULATION type string (or "I" if you happen to have numbers only without a unit like "k" for "thousand").
    Then please create a table with a TreeByKeyTableColumn namde LOCATION and an additional TableColumn called POPULATION. Now please add a TextView cell editor to both and bind the text value of each of them to the attributes LOCATION and POPULATION of the context node DATA. Last step is to bind the attribtues rowKey and parentRowKey(?) to the KEY and the PARENT attributes. This concludes the design time part.
    Next step is to fill the node DATA with actual data. Just use a supply function and do it like this:
    First entry:
    KEY = 'WORLD'.
    PARENT = ''.
    LOCATION = 'World'.
    POPULATION = '4 billion'.
    Second entry:
    KEY = 'DE'.
    PARENT = 'WORLD'.
    LOCATION = 'Germany'.
    POPULATION = '80 million'.
    You should now see a table with a tree at the left column that looks like:
    <pre>
      World        4 billion
       ->Germany   80 million
    </pre>
    Kind regards,

    As soon as you open a node in the ALV tree the report will stop at the break-point.
    Now you need to check if there are still children nodes to be displayed.
    If not then trigger your special coding.

  • Creating a tree structure like Windows file explorer using Jdev

    Hi All,
    Is it possible to develop a tree structure like windows in JDEV and then same page I want to move to oracle apps.

    Yes. This possible with ADF Faces RC, which provides an af:tree component. Have a look at the Fusion Order Demo, which uses the tree to implement a similar usecase to the one you describe.
