Highlight the selected Tree Node

Hello Everyone,
Can someone plz tell me how to highlight the selected tree node ?
After selection, user should be able to see which node was last selected.
Thanks

Hello,
for me it is not really clear what you have done. Sorry!
Because I have problems to paste code, I will describe how you can test that function.
Take the BSP application HTMLB_SAMPLES and copy it to ZHTMLB_SAMPLES. Take page "treeviewSample.htm" and add the following node behind node22:
<htmlb:treeNode id   = "node23"
                  text = "Node 2.2, normal text"
                  selection="PRIMARYSELECTION">
Perhaps this will show you how it works and help you.
As far as I can see the attribute "selection" can't be set via table.
Best regads

Af:tree - how do I highlight the selected tree node?

af:tree
I checked the generated CSS file. I found that when a tree node is selected, the related CSS attribute is:
.xj:link{
font-family:Arial,Helvetica,Geneva,sans-serif;
font-size:10pt;
font-weight:normal;
color:#663300
I created a customized CSS attribute, but then all of the links have the customized CSS attributes.
How do I just highlight the selected tree node link?
Thanks,

try doing the onclick javascript method
you have to place it on the node element and id must be made dynamic
for this use 'this.id'
by which the current id of the node is passed
and by capturing the id name in a var
use the same for invoking its selected property and make it true
like this
var currentid = this.id;
this.form.currentid.selected = true;

You should try Franks generic selectionListener http://www.oracle.com/technetwork/developer-tools/adf/learnmore/25-generic-tree-selection-listener-169164.pdf.

Error in Getting Selected Tree node From POPUPMENU

Environment: Forms 9i, 9i AS
The Folowing code is written with in POPUP MENU to get the selected tree node. It always returns 0. The samE code works fine with in any other TRIGGER. Is it Forms BUG?
v_sel_tree := ftree.GET_TREE_SELECTION(v_item,1);

Whether or not it is a bug you need a workaround.
How about getting the when-tree-node-selected to set a package variable and look at its value in the pop-up menu code.

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

ADF Tree 10.1.3.1, not highlighting the selected node.

Hi,
I'm having a problem highlighting the selected node in the ADF CoreTree.
I use the treehandler and model as described in the link: http://technology.amis.nl/blog/2116/much-faster-adf-faces-tree-using-a-pojo-as-cache-based-on-read-only-view-object-showing-proper-leaf-nodes-again
I use this objects because my tree was showing leaf node with the image to collapse.
The tree now looks great, the only problem is that when i click on a node the focusRowKey is set accordingly(debugging the getter and setter) but is not show as the selected node.
The tree jspx code looks the follow:
               
                                 <af:tree value="#{ActosTreeHandler.treemodel}" var="node"

                                           id="treeActos"
                                           varStatus="nodeStatus" binding="#{ActosTreeHandler.jsfTree}">

                                        <af:setActionListener from="#{ActosTreeHandler.jsfTree.rowKey}"
                                                              to="#{ActosTreeHandler.focusRowKey}"/>
                                        <af:setActionListener from="#{node}"
                                                              to="#{ActosTreeHandler.selectedNode}"/>

                                    </f:facet>
                                  </af:tree>Does anyone know how this can be solved?

Select tree node in tree component

hi,
i am developing a web site which has a site map as a tree component, the sitemap is a inserted in a page fragment, users could click tree nodes to go to corresponding pages. also on other pages, i have next and previous buttons which allow users to navigate through pages. the question is how can i update the tree component when users navigate using the next and previous buttons so that the correct tree node is highlighted?
i tried to use the selected property for the tree component, but it does not do anything.

Highlight an ADF tree node when it is clicked

Hello every onei ,
Does anybody has any idea how to highlight an ADF tree node when it is clicked ?
Here is my scenario:-
I have a popup which has a tree component on left and when we click on any node in the tree we have to display the corresponding page on right side.
As the tree is common for all pages in the popup, i created an XHTML template with tree. All the treenode pages will use this template to display the tree.This template i am using to implement in rest of the pages.
So when i click any link on this tree will load the corresponding JSP. But i am loosing focus. i mean selected node is not highlighting. Because we are loading the entire target page with template.
Could any let me know how to highlight the tree node ?
The Main problem is we are not using ADF controllers. We are using managed beans, these managed beans attached to the JSPX pages.
Kindly guide me if any one knows solution.
Thanks & Regards,
Sai Sravan.P

Hello Sai,
I am afraid you have posted your question in the wrong forum. This forum is about Oracle On Track Communication, a next-generation social enterprise collaboration product.
Please re-post your question in an ADF related forum and I am sure someone will be able to answer.
Thank you,

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.

How to highlight the selected value in a table

Hi All,
I have list of roles in a table like admin,dba...etc.
i will select the current selected role using
Stgin role =wdCotext.currentElement().getRole();
After getting the role i bind this value in context.
now my requiremnet is i will navigate to other table view containing all roles like admin,dba,networkadmin .
I have to highlight the selected role in previous table to new table containing the all the roles.
means selected role should be highlight in a next table view list of roles.
please help.

Hi mohammad,
To achieve this functionality, use another integer variable to store the index of the currently selected element in the first view. Pass this variable's value to the next view (either as plug parameter or throgh mapping) and set the Lead selection for the table as this index in the second view.
In the first View ....
int n = wdContext.current<your_node>Element().index()
pass this value from first view to second view.
In the second view
wdContext.node<your_node>().setLeadSelection(n)
Hope this helps,
Best Regards,
Nibu.

Clicking on TOC Item Jumps to Previous Identical Entry. How to highlight the selected one?

Win 7, 64 bit
RH 9 (latest patch)
HtmlHelp (CHM) output
I have many TOC pages that are identical.
For example, in our software some toolbar icons are repeated on different screens. In the built CHM help, if I click on a later identical page reference in our TOC, the TOC automatically jumps focus to the first entry. It doesn't stay on the selected entry.
This causes confusion as all of a sudden the user is in an entirely different context. How can I get it to highlight the selected item and not jump to the first reference?

Hi Jared
Note that this issue is generically related to any help system and isn't a "RoboHelp specific thing". When multiple points in a Table of Contents reference the same page, how is the system supposed to determine exactly which TOC node is the correct one?
The way past this is to create multiple distinct nodes from the TOC to the topic.
One way involves never creating an actual link from the TOC to the topic. Instead, create as many distinct topics as you need in the TOC and have them redirect to the desired topic. The bottom line is that the correct page is presented and the correct TOC node is highlighted.
Another way involves a similar approach. Create distinct topics that simply present an inline frame (IFRAME) that has the single "real" topic.
Yet another way involves another variation. Create a Snippet that is essentially the single entire topic. Then create distinct topics that only contain the snippet.
Hope this helps... Rick

How do i write the CTE for count the Binary tree nodes on level basis. Here is the example,
now,what i want to do is if i'm going to calculate the Count of the downline nodes.which means i want to calculate for '1' so the resultset which i'm expecting
count level mode
1 1 L
1 1 R
2 2 L
2 2 R
4 3 L
2 3 R
How do i acheive this,i have tried this
with cte (advId,ReferId,mode,Level)
as
select advId,ReferId,mode,0 as Level from #table where advid=1
union all
select a.advId,a.ReferId,a.mode ,Level+1 from #table as a inner join cte as b on b.advId=a.referId
select *From cte order by Level
i hope its clear. Thank you

INSERT INTO Employees VALUES(13, 7 , 'Dan' , $2000.00)
INSERT INTO Employees VALUES(14, 11 , 'James' , $1500.00)
The first request is probably the most common one:
returning an employee (for example, Robert whose empid=7)
and his/her subordinates in all levels.
The following CTE provides a solution to this request:
WITH EmpCTE(empid, empname, mgrid, lvl)
AS
-- Anchor Member (AM)
SELECT empid, empname, mgrid, 0
FROM Employees
WHERE empid = 7
UNION ALL
-- Recursive Member (RM)
SELECT E.empid, E.empname, E.mgrid, M.lvl+1
FROM Employees AS E
JOIN EmpCTE AS M
ON E.mgrid = M.empid
SELECT * FROM EmpCTE
Using this level counter you can limit the number of iterations
in the recursion. For example, the following CTE is used to return
all employees who are two levels below Janet:
WITH EmpCTEJanet(empid, empname, mgrid, lvl)
AS
SELECT empid, empname, mgrid, 0
FROM Employees
WHERE empid = 3
UNION ALL
SELECT E.empid, E.empname, E.mgrid, M.lvl+1
FROM Employees as E
JOIN EmpCTEJanet as M
ON E.mgrid = M.empid
WHERE lvl < 2
SELECT empid, empname
FROM EmpCTEJanet
WHERE lvl = 2
As mentioned earlier, CTEs can refer to
local variables that are defined within the same batch.
For example, to make the query more generic, you can use
variables instead of constants for employee ID and level:
DECLARE @empid AS INT, @lvl AS INT
SET @empid = 3 -- Janet
SET @lvl = 2 -- two levels
WITH EmpCTE(empid, empname, mgrid, lvl)
AS
SELECT empid, empname, mgrid, 0
FROM Employees

Results generated thus far might be returned (but are not guaranteed to be),
and error 530 is generated. You might think of using the MAXRECURSION option
to implement the request to return employees who are two levels below
Janet using the MAXRECURSION hint instead of the filter in the recursive member
WITH EmpCTE(empid, empname, mgrid, lvl)
AS
SELECT empid, empname, mgrid, 0
FROM Employees
WHERE empid = 1
UNION ALL
SELECT E.empid, E.empname, E.mgrid, M.lvl+1
FROM Employees as E
JOIN EmpCTE as M
ON E.mgrid = M.empid
SELECT * FROM EmpCTE
OPTION (MAXRECURSION 2)
WITH EmpCTE(empid, empname, mgrid, lvl, sortcol)
AS
SELECT empid, empname, mgrid, 0,
CAST(empid AS VARBINARY(900))
FROM Employees
WHERE empid = 1
UNION ALL
SELECT E.empid, E.empname, E.mgrid, M.lvl+1,
CAST(sortcol + CAST(E.empid AS BINARY(4)) AS VARBINARY(900))
FROM Employees AS E
JOIN EmpCTE AS M
ON E.mgrid = M.empid
SELECT
REPLICATE(' | ', lvl)
+ '(' + (CAST(empid AS VARCHAR(10))) + ') '
+ empname AS empname
FROM EmpCTE
ORDER BY sortcol

Adding image for the selected Tree leaf???

Hi All,
         I am working with flex tree component in which i have to add
an arrow image for the selected leaf node. I tried to do this using itemclick event
but cant make it. can you help me out in doing this???
Note: I have written custom Tree and TreeItemRenderer...

Thanks for ur reply Grizzzzzzzzz,
                                                is there a way to identify the selected leaf from within MyTreeItemRenderer(Extends TreeItemRenderer)?
                                               If this is possible,i can add the image to the selected leaf of the tree.
Right now i am assigning images to all the leaf nodes of the tree as follows:
public
class MyTreeItemRenderer extends TreeItemRenderer
* Override to draw a line in case current item is a leaf.
override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):
void{
// Call super method
super.updateDisplayList(unscaledWidth, unscaledHeight);
if(super.data){
if(TreeListData(super.listData).hasChildren){
// logic for parent node comes here
else{
//Adding leaf Image
//Logic to add images to leaf
myImage.source = leafImage;
myImage.x =
super.label.x;
//The above code adds images to all leaf nodes. CAN I ADD THIS IMAGE ONLY TO THE SELECTED LEAF NODE???
//HOW TO FIND THE SELECTED LEAF NODE FROM HERE??? SO THAT SELECTED LEAF WILL BE ADDED WITH THE IMAGE???
//The above code adds images to all leaf nodes. CAN I ADD THIS IMAGE ONLY TO THE SELECTED LEAF NODE???
//HOW TO FIND THE SELECTED LEAF NODE FROM HERE??? SO THAT SELECTED LEAF WILL BE ADDED WITH THE IMAGE???
THANKS,
