ALV doesn't expand/collapse subtotals

Hi everyone,
I have an old ALV program in wich i made some changes. For example, added form USER_COMMAND so that when you double-click on a row, it makes a CALL TRANSACTION to the referenced document.
But a problem emerged, and it didn't happended before. If i ask for subtotals, i can't manage to expand/collapse the rows, by using the icon on the yellow subtotal line(s). The small "finger" icon that appeared (like in hotspot), no longer appears.
What can i do to solve this ? thank you in advance to all.
Nuno Santos

I just realized this happens because i have an editable field on my alv. If i "disconnet" the edit mode, collapse/expand works fine again. Isn't there a way to workaround and make possible edit AND collapse/expand at the same time ?

Outlook 2013 - Online Archive folders do not remember expand / collapse

For our QA group, we have just upgraded them from Office 2010 to Office 2013 SP1. We have one user that noticed something. With Outlook 2010, the client would remember which folders he had expanded or collapsed under his "Archive" (the online archive
generated by the Archiving feature of Exchange server). However, once we upgraded him to Outlook 2013, this is no longer true. Now, the "Online Archive" header is fully collapsed when he open Outlook every time.
To test, I created a small folder structure with some items in my own "Online Archive" section and was able to reproduce this behavior. Outlook 2013 will remember which folders are expanded or collapsed for the folders in my Inbox but not for the
folders in my Archive. Is there a way to have Outlook 2013 remember the expand / collapse settings for the Archive?

Expand/Collapse option in Portal - SP13

Hi everybody!!
We have EP7.0 NetWeaver 2004s and we upgraded the SP from 5 to 13. When SP13 was installed, the icon to expand/collapse doesn't work correctly (Detail Navigation in Navigation Panel in the Light Framework). The icon always send the user to the main and first page. With the SP5 it works well.
Do you have any idea about how can I solve this??
Thanks in advance for any help that you can give me!
Best Regards,
Claudia

Hi Claudia,
Take a look at this thread maybe it gives you some answers...
How to disable automatic loading of iView/Page in detailed navigation?
We have SP13 at this moment and its working "fine":
1. When clicking on the expand/collapse icon (the triangle) the first navigation node in this folder/workset is NOT loaded automatically.
2. When clicking on the text part of the link (the actual url) the first navigation node in this folder/workset IS loaded.
In addition to step 2 you can steer what navigation node is loaded by setting the parameter "Default Entry for Folder" this property is by default set to No.
Also take a look at the property: "Clicking Folder Name Launches First Node" of the Detailed Navigation iView.. Maybe this is by some reason got set properly...
Good Luck,

Expand/Collapse query structure?

Hi all,
I'm working with a structure in a BW query. In this BW query you have the possibility to expand or collapse structure nodes. Is it possible to overwrite this property in Design Studio?
I tried to use the scripting formula DS_1.collapseNode("technical ID structure", "technical ID member structure") but it doesn't work.
Any ideas?
Thanks, Vanessa

Hi Vanessa,
I had the same case on my project(not a real hierarchy, but a structure).
I've implemented it using a button - I have an image of a + and a - that collapses and expands the hierarchy.
try to do it with a button or and image (in the onClick event). and if it works, you can call this event from startup or in background processing.
about your second answer, in design studio:
go to your datasource ->right click->edit initial view
there you will see the query exactly as you defined it in bex.
change the hierarchy expand\collapse state, and click ok.
the data in the crosstab will change accordingly.
hope it helps,
Roman

Expand/Collapse functionality in Survey

Dear Experts,
We have build survey Form using Survey Builder. The survey Form has 4
sections , in each section 5 questions & its relevant answer
options are there.
We are using the standard CSS style sheet : CRM_SVY_OPP_WINLOSS.CSS. Out
put displays standard HTML page with out Expand & Collapse
functionality at section & Questional level.
Client required expand and collapse functionality to view the entire
survey form in one page which allows the user to navigate to required
question .
For that we are tring to change Static Survey XSLT, however system is
not allowed to edit XSLT file .
Please suggest ,how can we enable the expand & Collapse
functionality for our surveys in Survey Buider ?
Regards
Pramod

Hello Aks,
After seeing the ME2ON transaction, what i can suggest you is following:
--> Display a column in your Grid with the hotspot on it
--> You can give the icon as a value in the column
--> Then for the hotspot click you need to display the expanded data i.e. regenerate the grid.
My suggestion to you would be that if you dont need to edit anything in the grid i.e. dont want have any editable field on the grid, then you should opt for an ALV tree using class CL_GUI_ALV_TREE. The expand collapse functionality is already there and you will be saved from a lot of coding.
Hope this helps.

Himanshu

Form - Expand/Collapse sections to simulate website, is this possible?

Hello,
My FLA file is based in CS5 with AS3. I posted this in the AS3 forum but if it can be done without AS3 then I am open to that possibility as well.
I am creating a non-functioning form, meaning I just need it to look like a form but the functionality doesn't need to work. Atleast not in this stage of development.
The functionality I need basically looks like the following:
- http://static.geewax.org/checktree/index.html (What would this be called in the flash world?? my google search terms have not been successful)
Where:
1. Clicking the arrow expands a section.
2. The arrow changes to a different arrow when the section is expanded.
3. It will be inside of a white box, the white box needs to resize to either shrink or get taller when a section is expanded or collapsed.
One section will be checkboxes, and one section will be radio buttons.
Thank you very much in advance . I look forward to exploring into how to accomplish such a thing.

Okay,
I know I may be going at this completely wrong but posting my code here so someone can give me feedback so far and point me in directions where I need improvement.
So far this code:
1. Expands/Collapses the 1st section, and properly moves the 2nd section to the correct position.
My problem so far is:
1. The contents of the 2nd section doesn't update to the correct position when section 1 expands/collapses.

Expand/Collapse feature in table maintenance view

Hello experts,
We have created a custom table and maintenace view. For some table rows, the only key value difference is an EFFECTIVE DATE. The generated table maintenace dialog by default "Collapses" the rows that only differ by Effective Date. Using the Expand <-> Collapse button, we can see the missing detail for individual rows.
Can the maintenace dialog be expanded by default?

Expand/Collapse a block in a selection screen

Hey Folks,
I have a requirement , where I have a selection screen, with 3 selection blocks. I have a requirement that I need to make 2 of these blocks expandible/collapsible on the toggle of a button.. How can this be achieved.
In case of a normal screen, I would have had to create the blocks as subscreens (one type of screen for expanded state...another for collapsed state) and called it from the main screen. But how do I achieve the same using the selection screens?
I was considering creating the blocks as subscreens in the selection screen and calling them in the PBO of the main selection screen. However, I am unsure if thats a wise thing to do since the screen is generated automatically in case of a selection screen and I do believe its not a good idea to manually alter it.
Does anyone has any pointers on this?
Thanks and Best Regards,
Puja.

[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

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”

How do I remove the "TOC" btn in the playbar WITHOUT removing the TOC "Expand/Collapse" icon?

I am working in CP7 on a project with a Table of Contents that is set to 'Overlay'. The client has requested that I remove the "TOC" button in the playbar, without removing the TOC "Expand/Collapse" icon, so that the user can still hide/reveal the TOC when necessary. The only control I can find is the "Show TOC" checkbox under Project > Table of Contents. However, un-checking this option removes both the "TOC" button AND the "Expand/Collapse" icons. Is it possible to remove just the "TOC" button in the playbar?

If you are using SWF output you can always edit the playbar in Flash and remove it.
If HTML5 you can edit the JavaScript out put to remove the button from the playbar.

ALV: how to display only subtotals and total rows in the output

ALV: how to display only subtotals and total rows in the output
i am getting output
i am getting subtotals for respective fields
but i want to display only subtotals and totals rows in the output
i have tried the
totals_only parameter in slis_layout_alv
but it is not working.

hi,
For TOTAL
For the amount field / quantity field in the field catalog give DO_SUM = 'X' for WHOLE total
For SUBTOTAL
For subtotal you will have to create an internal table sort..Let's say you want to do subtotal for each customer..
DATA: lt_sort type SLIS_T_SORTINFO_ALV,
ls_sort type slis_sortinfo_alv.
CLEAR ls_sort.
ls_sort-spos = 1.
ls_sort-fieldname = 'Give the field name that you do the sum'.
ls_sort-up = 'X'.
ls_sort-subtot = 'X'.
APPEND ls_sort TO lt_sort.
fieldcatalog-do_dum = 'X'.
for subtotals
WA_SORT-FIELDNAME = 'ERSDA'.
WA_SORT-SPOS = '2'.
WA_SORT-UP = 'X'.
WA_SORT-SUBTOTAL = 'X'.
APPEND WA_SORT TO IT_SORT.

Expand/Collapse all the Bookmarks in a PDF file

Hi,
This is my first message on the board :-)
I work with very large PDF files (i.e 2000 pages, 700 bookmarks on 5 or 6 levels!) and I'm looking for a script (Acrobat 9 Pro) allowing to expand/collapse all the bookmarks in a PDF file.
Thanks in advance for your valuable help,
Cheers
Antonella

The Acrobat Javascript Scripting reference (http://partners.adobe.com/public/developer/en/acrobat/sdk/AcroJS.pdf) describes how to use scripting to access bookmarks and how to open and close them, which is what you're looking for.
I suggest you read the reference and make a function that will do the job for you.
That's the way I would do it.
I don't think you can access the keyboard shortcuts "/" and "Shift + *" via scripting.

JTree with XML content expand/collapse problem

Hello all,
I'm having this very weird problem with a JTree I use to display the contents of an XML file. I use the DOM parser (and not JDOM since I want the application to run as an applet as well, and don't want to have any external libraries for the user to download) and have a custom TreeModel and TreeNode implementations to wrap the DOM nodes so that they are displayed by the JTree.
I have also added a popup menu in the tree, for the user to be able to expand/collapse all nodes under the selected one (i.e. a recursive method).
When expandAll is run, everything works fine and the children of the selected node are expanded (and their children and so on).
However, after the expansion when I run the collapseAll function, even though the selected node collapses, when I re-expand it (manually not by expandAll) all of it's children are still fully open! Even if I collapse sub-elements of the node manually and then collapse this node and re-expand it, it "forgets" the state of it's children and shows them fully expanded.
In other words once I use expandAll no matter what I do, the children of this node will be expanded (once I close it and re-open it).
Also after running expandAll the behaviour(!) of the expanded nodes change: i have tree.setToggleClickCount(1); but on the expanded nodes I need to double-click to collapse them.
I believe the problem is related to my implementations of TreeModel and TreeNode but after many-many hours of trying to figure out what's happening I'm desperate... Please help!
Here's my code:
public class XMLTreeNode implements TreeNode
     //This class wraps a DOM node

The collapseAll, expandAll code (even though I m pretty sure that's not the problem since they work fine on a normal JTree):
    private void collapseAll(TreePath tp){
         if (tp==null) return;
         Object node=tp.getLastPathComponent();
         TreeModel model=tree.getModel();
         if (!model.isLeaf(node)){
              tree.collapsePath(tp);
              for (int i=0;i<model.getChildCount(node);i++){
              //for (int i = node.childCount()-4;i>=0;i--){
                   collapseAll(tp.pathByAddingChild(model.getChild(node,i)));
              tree.collapsePath(tp);
    private void expandAll(TreePath tp){
         if (tp==null) return;
         Object node=tp.getLastPathComponent();
         TreeModel model=tree.getModel();
         if (!model.isLeaf(node)){
              tree.expandPath(tp);
              for (int i=0;i<model.getChildCount(node);i++){
              //for (int i = node.childCount()-4;i>=0;i--){
                   expandAll(tp.pathByAddingChild(model.getChild(node,i)));

Hi,
Iam not facing this problem. To CollapseAll, I do a tree.getModel().reload() which causes all nodes to get collapsed and remain so even if I reopen them manually.
Hope this helps.
cheers,

ADF TreeTable: selective expand/collapse of rows

Hi
I have a query. How can i selectively expand or collapse nodes in a Tree Table. I have got the tree model but i need to expand even further so that the nodes can be expanded/collapsed initially based on some logic.
It would be of great hhelp if any1 has some solution to it

This doesnt work
What i am doing:
1. I have a TreeTable
2. Its value is a TreeModel whose each node is my customized Object : MyObject
So if i use this kinda code which is in ur tutorial
CollectionModel model = (CollectionModel)tree1.getValue();
treeBinding = (JUCtrlHierBinding)model.getWrappedData();
I get a classcastexception:
MyObject cannot be cast to oracle.jbo.uicli.binding.JUCtrlHierBinding
since model.getWrappedData(); returns the root node of the tree which should be of my customized Object type

ALV doesn't expand/collapse subtotals
