How to Use Tree Structure in Forms (Expand & Collpse)

Hi ,
I need a logic to develop a Custom form which using tree structure fuctionality.It's like same in Indented Bills form (Module Bills of Material).
I have to use the symbol '+' and '-' in column called item_number ( if it has sub componentes, using that symbol i may explode or collopse).
I gone through the base form for that(indented Bill form(Form Name:BOMFQBIN, using BOMFMSTR library function to create Tree Structure)
but i colud not understand the logic.
If any one clarify me then it's fine
Thanks,
Sri

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
Regards

[Forum FAQ] How to use parameter to control the Expand/Collapse drill-down options in SSRS report?

In SQL Server Reporting Services (SSRS), drill-down is an action we can apply to any report item to hide and show other report items. They all are ways that we can organize and display data to help our users understand our report better. In this article,
we are talking about how to use parameter to control the Expand/Collapse drill-down options in SSRS report.
Consider that the report has a dataset (dsSales) with following fields: SalesTerritoryGroup, SalesTerritoryCountry, CalendarYear, SalesAmount.
1. The report has the following group settings:
Parent Group: SalesTerritoryGroup
Child Group: SalesTerritoryCountry
  Child Group: CalendarYear
   Details: SalesAmount
2. Add three parameters in the report:
GroupExpand:
Available Values: “Specify values”
Label: Yes           Value: Yes
Label: No            Value: No
Default Values: “Specify values”
Value: Yes
CountryExpand:
Available Values: “Specify values”
Label: Yes           Value: =IIF(Parameters!GroupExpand.Value="No",Nothing,"Yes")
Label: No            Value: No
Default Values: “Specify values”
Value: =IIF(Parameters!GroupExpand.Value="No","No","Yes")
YearExpand:
Available Values: “Specify values”
Label: Yes
Value: =IIF(Parameters!GroupExpand.Value="No" or Parameters!CountryExpand.Value="No",Nothing,"Yes")
Label: No            Value: No
Default Values: “Specify values”
Value: =IIF(Parameters!GroupExpand.Value="No" or Parameters!CountryExpand.Value="No","No","Yes")
3. Right click SalesTerritoryCountry icon in the Row Groups dialog box, select Group Properties.
4. Click Visibility in the left pane. Select “Show or hide based on an expression” and type with following expression:
=IIF(Parameters!GroupExpand.Value="Yes", False, True)
Select “Display can be toggled by this report item” option, and select “SalesTerritoryGroup” in the drop down list.
5. Use the same method setting CalendarYear, (Details) drill-down with following expression:
=IIF(Parameters!CountryExpand.Value="Yes", False, True)
=IIF(Parameters!YearExpand.Value="Yes", False, True)
6. Click SalesTerritoryGroup text box in the tablix. Select InitialToggleState property in the Properties dialog box, and type following expression:
=IIF(Parameters!GroupExpand.Value="Yes", True, False)
7. Use the same method setting SalesTerritoryCountry, CalendarYear text box with following expression:
=IIF(Parameters!CountryExpand.Value="Yes", True, False)
=IIF(Parameters!YearExpand.Value="Yes", True, False)
After that, when we preview the report, we can use these three parameters to expand/collapse drill-down.
Note:
In our test, we may meet following issue. We can check the expression of InitialToggleState property to troubleshooting the issue.

How to use "Reference Structure" setting in analysis grid item

Hello expert,
in Bex analyzer, how to use "Reference Structure" setting in analysis grid item by example?
Many thanks,

The variable needs assigned a value, that's why you're getting prompted. When you execute the statement, it's not executing the variable and exec lines.
Having script output available in a grid would be an enhancement request.

How to use css in oracle forms

Hello, I am using oracle forms 11g with weblogic server 10.3.5 at windows 7.I have to use CSS in oracle forms.i have tried to search it but no profit.please some one else tell me that how can use css in oracle forms. Thnak You regards aaditya

Hi
As Francois pointed out Oracle forms has nothing to do with html based technology. The way you can get the equivalent effect of creating consistancy in the way your objects are displayed is by creating a set of items you want and alter their apperance and behaviour and place them into object libraries (one library should do the trick). From there you subclass all of you forms items off these libraries.

How to use a structure at run time....

Hi gurus,
I am confused on how to use the structure in our report..why do we need it...Please help me with that...
Thanks
Cheers:Jim

Or you could simply use a structure in your program to group like fields together. So that you could maybe clear them all at one shot.
For example, say that you have a structure with fields a - z.
data: begin of structure,
        fielda type c,
        fieldb type c,
        fieldc type c,
        fieldz type c,
        end of structure.
So in your program, it is now important for you to clear these fields, if you would have defined them one by one without the structure, you would have to list them all in your CLEAR statement, but instead, since you have them in a structure, you can some say....   CLEAR STRUCTURE.

How to use event structure of event data nodes event filter nodes in programming

hi,
I need manual of how to use 'event structure' events of 'event data nodes' and 'event data filters'...please help me....
Regards
Ravindranath

I'm not really sure what you are looking for here. Did you do a search in the LabVIEW help for Event Structure?
The Event Data Node just returns information about the event, like control data, control reference, what caused the event, etc.
The Event Data Filters are just used in Filter Events. This allows you to discard an event or change the data that the event will recieve.

How to get Tree structure in JSP page?

Hi,
I would like get data from the database and display the data in tree structure with the check boxes at each nodes on a jsp page with out using any third party tools. how can i do that? Do i require any new tags to fulfill this requirement?
can any one help me out by sending any example code?
thanks in advance.
Regards,
Reddy

Once you have the data in a list or something, can't you just use <c:forEach> and then output standard nested <ul> and <li> tags to give the tree structure.
<html>
     <style>
          li
               list-style-type:none;
     </style>
     <body>
          <form>
               <ul>
                    <li>
                         <input type="checkbox">Check 1</input>
                         <ul>
                              <li>
                                   <input type="checkbox">Check 1A</input>
                              </li>
                              <li>
                                   <input type="checkbox">Check 1B</input>
                              </li>
                         </ul>
                    </li>
                    <li>
                         <input type="checkbox">Check 2</input>
                         <ul>
                              <li>
                                   <input type="checkbox">Check 2A</input>
                              </li>
                         </ul>

                    <li>

Heya Waleed,
I use spry to create an autocomplete form that works great across browsers that have javascript enabled. You can store info in a database and parse the info to xml for a dynamic approach. Take a look at the filter examples in spry.

How to use tree tables with CRUD operation for begineers ADF 11g

This is Friday night call for help.
This is only few sample ressources on the web for tree table and only one with CRUD operation.
I used this one http://jobinesh.blogspot.com/2010/05/crud-operations-on-tree-table.html because this is the only one that address CRUD.
And it is shaky. Deletion works fine but insertion not very well. This is working using custom code provided below.
Depending if the user selection in the tree, the code insert from the master node to the children node.
Any other options because it is not working well.
Also where Oracle describes how to use the row, rowset, itorator API? This is really hard to understand like almost if we should not use it.
then if not how can I insert in tree with two nodes and insert in the parent or children depending the users selection.
Lately I 'been posting questions on this forum with no response. This hurts. I understand developers cannot spend their time on this but People from Oracle, please help. We pay licenses...
public void createChildren(RowIterator ri, Key selectedNodeKey) {
final String deptViewDefName = "model.DepartmentsView";
final String empViewDefName = "model.EmployeesView";
if (ri != null && selectedNodeKey != null) {
Row last = ri.last();
Key lastRowKey = last.getKey();
// if the select row is not the last row in the row iterator...
Row[] found = ri.findByKey(selectedNodeKey, 1);
if (found != null && found.length == 1) {
Row foundRow = found[0];
String nodeDefname =
foundRow.getStructureDef().getDefFullName();
if (nodeDefname.equals(deptViewDefName)) {
RowSet parents =
(RowSet)foundRow.getAttribute("EmployeesView");
Row childrow = parents.createRow();
parents.insertRow(childrow);
} else {
RowSet parents =
(RowSet)foundRow.getAttribute("EmployeesView");
Row childrow = parents.createRow();
childrow.setAttribute("DepartmentId",
foundRow.getAttribute("DepartmentId"));
parents.insertRow(childrow);
} else {
System.out.println("Node not Found for " + selectedNodeKey);
}

I am looking for a sample that describe how to design a jsf page with a tree table.
So you have Department and employees. In the tree first comes Department and if you click the node you see the employees assigned to this department.
I need to be able to insert a new department or a new employee from the tree table by clicking on a insert button in the panel collection toolbar depending on user selection in the tree.
I got part of it working but not good enough.
By problem is the get insertion working
I have a createChildren method in my AM implementation that get in input a RowIterator and selected node key.
To goal is to create new records depending of the user selection and the input parameters get populated by the binding like this:
#{backing_treeSampleBean.selectedNodeRowIterator} #{backing_TreeSampleBean.selectedNodeRowkey} via method binding with parameters.
Is it the right approach?
First to be able to insert a parent record, I select nothing in the tree and ri and selectedNodeKey comes to null
we run this code
ViewObjectImpl vo = getSchHolidaySchedExceptionsView1();
//ViewObjectImpl vo = getDepartmentsView1();
Row foundRow = vo.first();
Row childrow = vo.createRow();
vo.insertRow(childrow);
A new blank entry appears in the parent node and we enter a value.
The the problem starts when we want to add a child to this parent.
We select the created parent and press the insert button, this code get executed
if (nodeDefname.equals(deptViewDefName))
//list of the children of the parent and create an new row
RowSet childRows = (RowSet)foundRow.getAttribute("SchHolidayExceptionDatesView");
Row childrow = childRows.createRow();
childRows.insertRow(childrow);
But the new entry does not appear, it is almost like it would be created for a different parent because this is a mandatory field that is not feel in yet and the interface complaints of a missing value. It is created somewhere just not a the right place... This is my guess.
Do you see something wrong with the code?
The full code og my create children method is there below
I am using jdeveloper 11.1.1.3.0 any issues with tree table to know about with this version?
Thanks for your help
public void createChildren(RowIterator ri, Key selectedNodeKey) {
final String deptViewDefName = "com.bcferries.app.pdfroutesched.model.SchHolidaySchedExceptionsView";
final String empViewDefName = "com.bcferries.app.pdfroutesched.model.SchHolidayExceptionDatesView";
if (ri != null && selectedNodeKey != null) {
// last row
Row last = ri.last();
Key lastRowKey = last.getKey();
// if the select row is not the last row in the row iterator...
Row[] found = ri.findByKey(selectedNodeKey, 1);
if (found != null && found.length == 1) {
// foundRow is the row selected
Row foundRow = found[0];
// The row selected can be the parent node or the child node
String nodeDefname = foundRow.getStructureDef().getDefFullName();
// if parent row
if (nodeDefname.equals(deptViewDefName))
//list of the children of the parent and create an new row
//works but we try to resolve the creation of a parent
RowSet childRows = (RowSet)foundRow.getAttribute("SchHolidayExceptionDatesView");
Row childrow = childRows.createRow();
//childrow.setAttribute("HolidayDate", new java.util.Date().getDate());
System.out.println("insert child row from master");
childRows.insertRow(childrow);
} else
//RowSet ParentRow = (RowSet)foundRow.getAttribute("SchHolidaySchedExceptionsView");
//RowSet childRows = (RowSet)ParentRow.first().getAttribute("SchHolidayExceptionDatesView");
Row childrow = ri.createRow();
System.out.println("insert child row from child ");
} else {
System.out.println("Node not Found for " + selectedNodeKey);
} else {
System.out.println(" param null try creating for first row : " +
ri + " * " + selectedNodeKey);
ViewObjectImpl vo = getSchHolidaySchedExceptionsView1();
Row foundRow = vo.first();
Row childrow = vo.createRow();
vo.insertRow(childrow);
}
