Expanded tree view by default

I have created a tree and placed it in page 0 using application express 3.1
On the initial page load my tree is not fully expanded and it comes along with "up" link as given below:
Parent node1 (up)
subnode1
subnode2
But the tree should appear in the expanded mode on the initial page load itself with out the "up" hyperlink as below:
Root node+
Parent node1
subnode1
subnode2
Parent node1
subnode1
subnode2
can any one give a suggestion on this?
Thanks in advance

Varad,
I tried doing that
By default the URL will take "::NO::FSP_AFTER_LOGIN_URL:" value.
But i forced my URL with ":up:NO::P0_TREE_ROOT:1000" which gave me an expanded mode.
In my application i am using conditional cache. if the url is changed for expand mode then cache is not enabled.
can you suggest me some other way.
thanks and regards

How to make the APEX tree in the "Expand All" shape by default?

Could anybody please enlighten me on how to make the APEX tree in the "Expand All" shape by default please? I created an APEX tree and by default it's in the "Collapse All" shape. I am using APEX 4.1.0.00.21

Hi,
you can check the view source of html and check the onclick code written on that plus sign(Expand All), just copy that onclick javascript code and put it on page javascript event.

Tree view in collapsed mode by default

Hello Experts,
Could you please explain how to get a tree view collapsed by default?
My scenario:
When looking for a Marketing Segment, the system displays the result with a tree view in expanded mode, containing all the Profile Sets with their profiles and Target Groups.
I would like to have the tree view in collapsed mode by default with only the Profile Sets displayed. Then, if need I would expand a given Profile Set to display its Profiles and Target Groups.
Component: SEGAS_SEG
View: RTSEG
Thank you very much for your answer.
Best Regards.

Hi,
     Have a look at the context node SEG in the view RTSEG. You will see a method REFRESH. The following lines are responsible for the automatic expansion.
        IF search_roundtrip = abap_true AND lv_index < 20.
          lr_root->expand_node( ).
        ENDIF.
Going by what you say, you will want to comment out these lines. If your component/view is not enhanced, enhance it and redefine this method. Copy the standard code and alter it. You need to alter this code to suit your requirement. For enhancing the component/view, you can find wikis in the CRM WebClient UI section.

Expand=false for Tree view control

Hi
I have a placed a tree view control on SharePoint 2010 master page and given sitemap as a datasource.
and my tree view is displaying all the links from sitemap file.
But here the problem is all the node are getting expanded.
Is there any way to disable that.

Assuming you are using SPTreeview control you can set ExpandDepth property. This property gets or sets the number of levels that are expanded when a TreeView control is displayed for the first time.

Nuke default PAN setting when expanding track view in multitrack project

I have not been able to find the following preference to change: When I expand the view of a track in a multitrack project, the default is for VOLUME and PAN to appear. I only want VOLUME. Every time I open a multitrack project after saving it with the PAN unchecked, it shows up again. Anyone know how to change the default settings for this?
Thanks

Thanks for the reply. I guess I did not miss some little option some place. Here is another default question for you: when I open a new multitrack project, SUBMIX 1 is always set to 1-6 SURROUND whereas I would prefer it to be 1-2 STEREO. At least that one seems to stay as STEREO after I have changed it and saved the project, but is there a way to change that default setting to have STEREO 1-2 in SUBMIX 1 from the start?

Display data as a tree view on IE5

Thanks for the backup :-)
A new version of the Tree Tag will be out some time this summer, by the way. It features:
1) The possibility to attach an object to a tree node (getObject(), setObject(...)).
This means you can display more information in the tree than just what is available
on the tree node itself. The information in this attached object can also be displayed.
This attached object can for instance be rendered by Struts's <bean:write ...> tags
2) Client side event listeners.
A new tag will be added that will only evaluate it's body when a node is expanded, collapsed,
selected or unselected. This way you can have a small bit of javascript sent along with the tree html to the browser, when a node is expanded/collapsed or selected/unselected, that for instance reloads the page in another frame in the browser
3) The <tree:tree...> tag will be able to detect selected/unselected nodes by itself, if the select request is sent to the page containing the <tree:tree tag>. In the current version only expands/collapses are detected automatically. This new feature is implemented to support the client side event listeners.
4) Someone asked for no-arg contructors of the TreeNode for use with reflection. They will be added to.
A larger, more detailed manual will probably also be available for a small fee, in addition to the free basic user guide and the free web app. example.
Look out for it ;-)

Hi Anna,
If you want to replace the Quick Launch part with the custom treeview web part in master page, you can comment out or remove the quick launch code block "",
then insert the custom web part snippet code in proper location in seattle master page, then all pages inheriting the seattle master page will have this web part.
Note, please back up the master page before customizing the original master page for recovery.

Thanks for the reply. I was able to create the tree view. Now I have two requirements related to this.
1. How to have them as collapsible menu structure, which gets expanded as and when user wants.
2. Can we customize it as, Whenever a user add as page in favorites, it will ask for to to put in some folder that is there under my favorites links? I belive it requires some programming customization. Could you guide me, for some solution.

hello pradeep,
for adding icons in the tree, u willhave to look closely to the
data format for the tree.in the data format used for populating
the tree we are supplying 5 fields. the state of the tree node
(expanded or collapsed), the depth of the node w.r.t the parent
node, the node value, the node label(what we see on the tree)
and the node icon which we want to use. for the node icon we
have to provide the entire path of the icon file. that's it.
hope this will solve the problem

Table with tree view on master column

Hi,
I'm trying to generate a table with tree view on the master column and I get the table values from an RFC.
The problem is that I need to control some properties like "expanded" or "isLeaf" and I can't add the value attributes to the model node to control the rows.
Any ideia on how to overcome this (what i think is a) problem?
Thanks for the help.
Pedro Barbosa

Hi Subramanian,
Maybe I didn't explain myself right. I also followed that tutorial with success but in this case i have on my custom controller:
-MyNode (model node)
- Output
- MyTable
- attribute 1 (model attribute)
In my context/view controller the only way i can map that node is by using a model node referecing "MyTable" but this way i can't add any of my attributes to same level of the attributes (is that the ideia right?).
I also tried to recreate the structure in the view with value nodes and value attributes with the same type as the model attributes and then bind them but i always get "Incompatible context element type".
Am i missing something?

SQL editor with tree view

We are working on some extraordiary long SQL stored procedure. Due to the shear size and IF/ELSE nesting it is very tedious to understand the logic .
What I am looking for is an SQL editor with tree view, where we can see IF/ ELSE, LOOP etc block as nodes. For example expand a node and see all blcoks of code within it.
+ IF block 1
expand---
-IF blcok 1
+IF block 1.1
+IF block 1.2
further expand
-IF blcok 1
+IF block 1.1
-IF block 1.2
IF block 1.2.1

Do some Google searches for a text editor that supports "folding".

Issue in Tree View Enhancement

Hello Experts,
I have a Tree View and its related Context Node Class. Due to some requirement I need to enhance the same.
I have done the following steps:
1. Enhance the View which eventually enhanced the CTXT class to Z_CTXT as well.
2. I am trying to enhance the Tree View context node( say IBASE in my example).
When I do the same, it is giving me an error saying that
Method CTXT - CREATE_IBASE does not exist.
Just to recheck I went to the parent class of Z_CTXT which is CTXT and found the method was very much there.
Refer standard component ICCMP_IBASE View: IBTreeResultList Context Node: IBASE. My question is related to this context node.
Thanks in advance.
Best Regards,
Vinamra.

Hi Vinamra,
When you enhance the view by default CTXT class also will be enhanced, when you enhance the context node then only system will create corresponding method create_"context node name" in your Z_CTXT class.
Did you check Z_CTXT class for the create_ibase method, This class should have added this method with code like this
model   = owner->create_model(
     class_name     = 'ZCLICCMP_IB_IBTREERESULTL_CN00' "cl_crm_ic_ibase_constants=>gc_ibtree_firstlevel_class "#EC NOTEXT
      model_id       = cl_crm_ic_ibase_constants=>gc_ibtree_node_name ). "#EC NOTEXT
ibasetree ?= model.

Are workmanagers visible in the jndi tree viewer?

Hi, I'm trying to setup a workmanager, and I'm having a few problems, but I'm just wondering if I'm falling at the first hurdle. I've tried creating workmanagers at the global and application level, but looking in the admin console for my server they never show up in the jndi tree viewer. Should I expect to see my workmanager there? If I look in the deployment then I do see that the workmanager exists, alongside default.
Thanks.

If you create a workmanager at the application level, you'll see the work manager in the console under Deployments -> your app -> Monitoring ->Workload.
If you create a workmanager at the domain / server level and reference it within your app's deployment descriptors ( wl-dispatch-policy ), you can look under Servers ->your app's targeted server -> Deployments -> your app -> Monitoring -> Workload. In this case, you'll see all the workmanagers targeted to that server, but you can confirm your app's usage of the correct wm by submitting a request to your app and seeing an increase in the completed requests column of the display.
A work manager configured at the domain / server level doesn't have a JNDI name attribute that you enter. You just use the same workmanager name in your deployment descriptor <wl-dispatch-policy>someWM</wl-dispatch-policy>.
The handling of stuck threads seems to be a trouble point for application defined workmanagers, so we've decided to stick with individual server level work managers for each app.
