Simple Requirement in Tree UI element

Hi All
I have the following requirement which is very simple in webdynpro java but the same changes are not reflecting in Tree UI element.
I have created the context struture as follows and i added this context node to the dataSource property of the Tree UI element.
but at the runtime the tree elements are not displayed as i added the context structure to the dataSource property.
i am getting the blank tree at runtime there is no elements at all.
Can you let us know if any settings are required to change the Tree UI properties.
Context Node Structure
A
A1
A2
B
B1
B2
C
C1
C2
Any pointers on this then it would be great help to me
Thanks

Tutorials and Documentation on Tree UI Element for ABAP

Hi Everyone,
I am having trouble finding documentation or tutorials on creating Tree structures in web dynpro for ABAP.
Basically, I need some tutorials on using the "Tree" UI Element. Also, how would I go about adding Check Boxes to such a control? For example, someone would like to select the lowest item in a Tree using a check box.
Tank you.
Christiaan.

Hi
>a) How to check or how to write the code to check whether the current selected node is first level or second level or third level etc from the above example tree structure
In the context node you have to have attribute level (integer). When you populate context nodes for the tree you have to set correct value 0, 1, 2, ... for the attribute. Then it'll be easy for you to read the value and understand what is the level.
>b) How to insert a node only at the first level , second level and third level i etc from the above example
It slightly depends on whether you use recursive nodes or not. But in general it's simple - just create a new element in the corresponding node
>c) How to delete only leaf node . i have a requirement which says that i can delete only leaf nodes , if i delete a node which having children then it should not allow to me. i can delete a node which is not having any child
IWDNode node;
if (node.getChild("<child node name>").size() <= 0) {
// leaf node
>4) How to rename any node, once user selects any node then on click of any button then popup opens which retrieves the current textvalue of a node and user have an inputfield where he enters then on click of save then that new textvalue needs to be updated to the selected tree element
Just bind the text property of a tree item to some node attribute (let say NAME). The just update a value of the attribute.

Webdynpro tree ui element

hi all,
i want to know from which tables can i pick the skill group and skills related to each skill group. And after getting these details i want to display them in the tree structure in my iView .
it is very urgent can any body help me regarding this issue.
Thanks & Regards,
Sreelatha Gullapalli.

Hi,
for tree UI element look into the below PDF...
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/f0ec6622-8da5-2a10-349b-868b6a553efa
and for binding data to a table... simple way to do it is just right click on your container in LayOut tab and then click on Apply template, from there select Table and then select the corrosponding Context node from which you want to display data into the table....
hope it will be helpful....
Reward points if useful...

Drag and Drop in feature in Tree UI element

Hello All,
The requirement is as following. The webdynpro screen should show two nodes Node1 and Node2. Each node would have some attributes.
Node1
__AAA
__BBB
Node2
   |__XXX
   |__YYY
It should be possible to drag and drop attributes from node to another node(Example , cut YYY from Node2 and add it to Node1).
Now can we achieve this using Tree UI element? Please let me know your inputs?
Regards,
Raghu.

it should be possible according to sap help[http://help.sap.com/saphelp_nw70ehp1/helpdata/en/a5/bf47414eca430794189fbb5919cc2f/content.htm|http://help.sap.com/saphelp_nw70ehp1/helpdata/en/a5/bf47414eca430794189fbb5919cc2f/content.htm]

In tree UI element inserting values from database

hai all,
Iam using tree UI element where I need to load the elements from database in tree.when the root node is selected the selected root node should be given as input to database and the subelements should be loaded to that particular root node.I ha ve alraedy gone thru the links in sdn where only static values are inserted in tree so plz help me to do that dynamically.Any suggesstions and guidance provided with this regard will be greatly appreciated.Its very urgent so plz help me in this .
Thanks n Regards
Sharanya.R

hai armin ,
how to get the selected value and give that as input and get the child nodes of tree loaded.iam not able to get that.also the user selected values need to be stored in database at last.how can this be done?

My code to "select" an element in the Tree UI element is not consistently working

Hi,
I created a Web Dynpro component that does many things. One feature is do display information in a Tree UI element. I use the TreeNodeType and recursive context node to build a nice tree representing what the customer wants. Since this tree could get very large, I implemented a search feature to help users locate items in the tree. When found, I expand the tree, and call call set_lead_selection passing in the element where found. This seems to generally work fine (and highlights the highlights the desired TreeNodeType), but only when going farther down in the tree. If I change the search so that it should find something "higher up" in the tree, the search still works, and it finds the data, but calling the set_lead_selection does not seem to unhighlight a previously located TreeNodeType. I have added code to loop through all elements in the tree and call set_selected( ABAP_FALSE). This didn't seem to help. If I use the mouse and manually click on the root of the tree, it seems deselect previously highlight TreeNodeTypes, and the highlighting works again (but still just going forward).
I implemented a Find Next feature that starts where the last search left off, and looks farther down the tree. This works more consistent, but still occassionaly seems to "forget" to unhighlight a previously located TreeNodeType/element.
What am I doing wrong?
I am attaching a screen shot.

Hi Perry,
Before setting the lead selection of found result, try to clear all the selected elements from context node.
Sample:
               data lo_node type ref to if_wd_context_node.
               lo_node = wd_context->get_child_node ( name = 'MY_NODE' ).
               "Clear the current selection
               lo_node->clear_selection( ).
               " now, set the lead selection
                lo_node->set_lead_selection( .... )
Hope this helps you.

Rama

Accessing BAPI through Tree UI Element

Hi,
I have one Tree Structure where i have to populate one BAPI and display the data on the browser .I have created two tree node elements and finished the binding .The tree is getting diaplayed in the browser.
But i am facing difficulty in populating data from the BAPI into the tree .
I tried to search in web dynpro tutorials regarding this but the exmples for tree are not much useful .
They are populating manually created data and not the data from BAPI .
Can anybody suggest me how to do this.If anybody can suggest some other tutorials for this then it will be very much useful for me .
Thanks.

Hi,
take a look at this:
http://help.sap.com/saphelp_nw04/helpdata/en/13/4cde139306304480e89d815ffcf891/content.htm
here you will find links to create recursive as well as non-recursive tree.
Though the example is of value node, you can extend that to be done from BAPI node. Simply replace the loop of value node by loop which iterate through the BAPI model class' output node.

Urgent support by two simple requirements

Hello,
i need support by two simple requirements.
Can someone tell me, whether it is possible to realize these in context of SAP XI /SAP Web AS
Graph showing relationships between Tables, DB Spaces & OS File system?
(Yes/No)
Can all jobs and/or scripts be re-run after failure without risk to production data (i.e. stepwise recovery)?
(Yes/No)
Thank you very much!
Regards
A. Henke

Hi Axel,
As far as your first requirement is concerned we can do that in SAP WAS very well with the help of WebDynpro. You need to use Business Graphics for that purpose, see the following link for details,
/people/sap.user72/blog/2005/03/23/business-graphics-in-webdynpro
Well for the other one you need to use job scheduling in JAVA with the help of say Quartz or something like that so that you can run timely jobs.
I hope it helps you.
Best regards,
Guru.

B11
B12
B13
B2
B3
C
C1
C2

C4
Can you please let me know How to rename of nodes A,A1,B,B1,B11, and C21??
my requirement is once i select any node either parent or child node or any node then popup opens where current value of a node can be retrieved and user can enter new name where he/she enters new name then that new name could be renamed to the selected node on click of an action.
If any body helps for sample code on this requirement then it would be great help to me.
Thanks
Kalki Reddy

In release >= 7.1 I would do that using a context menu. In earlier releases you could use a static menu at the TreeNodeType or TreeItemType. But I would not open the renaming dialog on selection of a tree node.
How to do that with a static menu?
- Add menus to the TreeNodeType/TreeItemType instances of your tree.
- Create an action "RenameTreeNode" with a parameter "treeNodeContextElement" of type IWDNodeElement.
- Add MenuActionItem to the menu, assign above action and define event parameter mapping "nodeElement" -> "treeNodeContextElement"
Then you will know the context element that represents the tree node where the menu is opened in the action handler of the menu item. In the action handler, open a popup window with an input field to enter the new name for the tree node. Use context mapping to pass the inout field value to the view controller that opens the popup. In the close action of the dialog, assign the edited value to the context element representing the tree node.

Unable to set state to 'required' for RadioButtonGroupByKey UI element

Hi all,
I'm using RadioButtonGroupByKey UI element that is bounded to a simple type.
Simple type looks like this:
0 -- Sunday
1 -- Monday
2 -- ...
The selectedKey property is bounded to the simple type.
The state property is set to 'required'
Although I'm using a radio button I don't want to set default selection.
I cannot set label for RadioButtonGroupByKey (unlike inputField).
I'm expecting to see a red asterisk near the radio button but I don't.
What else do I need to set in order to see the red asterisk?
I'm using 7.00.14

Is There A Way To Create A Simple File/Folder Tree...

Hi,
Please forgive me if this has already been covered but I have searched and found no answer...
I am trying to create a web page to run on my local network, through iweb and apache, and have got everything I need working except this. I aim to be able to access my work files (masses of word documents and power-points) through the website but I can see no obvious way of doing this through iweb (short of adding individual hyperlinks to each file). Is there a tool or process I can use to create a simple folder tree in html that I can add to my site that lists all my files and allows my to "save target as" in windows (our college techie is still devoted to windows) ?
Thanks in advance for any help...

If you wanted to send a video as an mms from a mobile phone, the best option for exporting would be 3G in the quicktime export menu ( File > Export and it's in the drop down list).
Keep it short and small and you shouldn't have any probs. There are some miserly operators out there who block MMSs bigger than 100K

Check box in Tree ui element.

Hi All
I am using org.eclipse.swt.widgets.TreeItem for creating tree structure. Now I am trying to incorporate check box for last tree element. For example if I am preparing tree structure for files the check box should appear only for text file not for directory. User would select the file by checking the box. Here is my code..
for (int i = 0; i < files.length; i++) {
TreeItem item2 = new TreeItem(item1, 0);
item2.setText(files.getName());
item2.setData(files[i]);
if (!files[i].isDirectory())
//here i have to do some thing so that i can select the file in check box
if (files[i].isDirectory()) {
new TreeItem(item2, 0);
I cant use java script here. So pls help me out without using js.
Thanks a lot.
