Hello Nilesh,
//Create ISimpleTypeModifiable to fill the dropdownbox
//XXX is your Desc field
                IWDAttributeInfo soAttribInfo= wdContext.getNodeInfo().getAttribute("XXX");
                ISimpleTypeModifiable soType = soAttribInfo.getModifiableSimpleType();
                soType.setFieldLabel("XXXX");
                IModifiableSimpleValueSet soSet= soType.getSVServices().getModifiableSimpleValueSet();
                soSet.clear();
                //To Get desc and key from web services you pass some information to the run the given Webservice do it here
                wdContext.currentRequest_XXXViDocument_getDescnKeyArrayElement().setInfo(infonr);
                wdThis.wdGetXXXController().getDescObjects();
                int size = wdContext.nodeResult_getDescObjectsArray().size();
                if (size != 0)
                     //Filling the desc in the dropdownbykey field
                     for (int i=0; i<wdContext.nodeResult_getDescObjectsArray().size(); i++ )
                          IPrivateXXView.IResult_getDescObjectsArrayElement soElement =
                              wdContext.nodeResult_getDescObjectsArray().getResult_getDescObjectsArrayElementAt(i);
                           soSet.put(soElement.getkey(),
                          soElement.getDesc().trim() + " " + soElement.getkey().trim() );
Implement this code for populating the drowdown when that works I can tell you the next step.
Good Luck,

Subject: Drop Down By index Vs Key

Question: I have domain with Fixed value and i want the drop down in webdynpro screen to pick the domain value automatically
what type of drop down should be used and can you differentiate the two types
kindly reply

Hi,
You should use drop down by key in order to select the domain value automatically.
Map your contxt attribute as a selected key property of the UI element property.
Diff. b/w the two avalable types:
For drop Down by index, You need to build the value table to the node intially and an intial value will be space by default.
For drop Down by key: you have val-nam pair i.e if you can decide to display domain value or description.
Hope this may be helpful.
Thank you

Hi Experts,
I have a drop down by index to which i binded one internal table,but m not able to get the default value

Hi Shan,
As per your requirement,When ur binding the internal table to the drop down by index ,but your are not able to get the default value.
For this please check this code.
In this I hv taken a node - dropdown1 and within this attribute of type Land1 and I hv set the cardinality to 0..n.
Then I hv bind the text property of the dropdownbyidx ui element to the node attribute.
then i hv call this code in the init method of view.
DATA lo_nd_dropdown1 TYPE REF TO if_wd_context_node.
DATA lo_el_dropdown1 TYPE REF TO if_wd_context_element.
DATA lt_dropdown1 TYPE wd_this->elements_dropdown1.
DATA ls_dropdown1 LIKE LINE OF lt_dropdown1.
navigate from <CONTEXT> to <DROPDOWN1> via lead selection
lo_nd_dropdown1 = wd_context->get_child_node( name = wd_this->wdctx_dropdown1 ).
@TODO handle not set lead selection
IF lo_nd_dropdown1 IS INITIAL.
ENDIF.
get all declared attributes
lo_nd_dropdown1->get_static_attributes_table(
    IMPORTING
      table = lt_dropdown1 ).
SELECT land1 FROM t005 INTO CORRESPONDING FIELDS OF TABLE lt_dropdown1.
CALL METHOD lo_nd_dropdown1->bind_table
    EXPORTING
      new_items            = lt_dropdown1

How to hard code values in drop down by index

Hi everyone
I hav a node containing 2 attributes ie value n key. I am using drop down by index. Value attribute is bound to my drop dwn box. In key I am providing key value for the value. I need to hard code 3 value..Can anyone help me how to do so.
Thanks
Jaspreet Kaur

Hi,
Example for Data Binding of the DropDownByIndex UI Element:
Procedure at design time:
       1.      Create a view with the name TestView.
       2.      Insert the DropDownByIndex UI element as a container child of the TestView view. (Step 1)
       3.      Create the context structure, as described in step 2.
Create the context node X with the cardinality 0..n. Insert the value attribute y of the type String into this node. Then perform the data binding of the DropDownByIndex UI element in the Properties window of the View Designer. The texts property must be bound to the value attribute y with the context path description TestView.X.y (step 3).
The context path TestView.X.y describes the attribute y in the context node X of the view context of the TestView view.
You can fill the context with test data using the following controller implementation.
public void wdDoInit()
    //@@begin wdDoInit()
   String[] letters = new String []
   {"A", "B", "C", "D"};
//Create context elements for the node "X"
   List nodeElements = new ArrayList();
   for (int i = 0; i <letters.length; ++i)
      IPrivateTestView.IXElement xElement = wdContext.createXElement();
      xElement.setY(letters<i>);
      nodeElements.add(xElement);
//Bind node element list to the node
   wdContext.nodeX().bind(nodeElements);
//Set nodes lead selection which determines the selected item
   wdContext.nodeX().setLeadSelection(1);
    //@@end

How can I add values on a Drop Down by Index Webdynpro Element?

Hi every body
Can anybody help me?
How can I add values on a Drop Down by Index Webdynpro Element?
How can I invoque my element on the Implementation Webdynpro?

Hi Jesus,
You can add elements to your DDbyIndex like this:
//Example: Popular un Dropdown by Index usando Nodos de contexto
// NODE[Card: 1..n, Sele:1..1] Si es obligatorio;            ||    NODE[Card: 0..n, Sele:0..1] Si no es obligatorio y se puede dejar en blanco
//Assuming we created a node called "Source", with a string attribute called "Texto" binded to the dropdownbyindex
for (int i = 1; i <= 101; i++)
     ISourceElement sourceElement = wdContext.createSourceElement();
     sourceElement.setTexto("Text number "+i);
     wdContext.nodeSource().addElement(sourceElement);

How can I add values on a Drop Down by Index Webdynpro Element by a Model?

How can I add values on a Drop Down by Index Webdynpro Element with a Model RFC?

Hi Jesus,
Please use the below code for DropDownByIndex Elements :-
Suppose you have model node ABC and attribute xyz. Now you have created custom node CustNode and attribute CustAtt.
ICustNodeElement ele = null;
if(wdContext.nodeABC().size > 0)
              for(int i=0; i< CustNode< wdContext.nodeABC().size; i++
     ele = wdContext. createCustNode();
                      ele.setCustAtt(wdContext.nodeABC().getABCElementAt(i).getXYZ)
     wdContext.nodeCustNode.add(ele);

How to capture selected value from drop down by index

Dear friends,
i want to capture the value of select value from drop down by index, for eg if select air france, how to capture , could any one please let me know
Thanks
Vijaya

Hi Vijaya,
You can get the value of selected from drop down as below
Check out the event handler method attached to Onselect event of the ui element drop down by index , if no event is associated, then create an event and attach to the drop down list
Now you will be having the CONTEXT_ELEMENT in the WDEVENT parameter
               data lo_element type ref to if_wd_context_element.
               lo_element = wdevent->get_context_element( name = 'CONTEXT_ELEMENT').
Now, you can get the static attribute value of selected drop down value & let us say your drop down list values are populated from context node 'ND_DRP_DOWN'
               data ls_data type wd_this->element_nd_drp_down.
                         lo_element->get_static_attributes(
                                   importing
                                   static_attributes = ls_data ).
Hope this helps you.

Drop Down By Index

Hi Gurus,
I've one problem with the Drop Down By Index in the WEBDYNPRO JAVA.
I'm filling the Drop Down By Index from the node based on some condition.
Based upon the condition the node has only one record.
After adding the node data to my drop down by index i'm getting the data but the problem is i'm getting two rows in the drop down by index.
First one is Empty string and the second is the actual value.
I've written some logic on the "onselectionchange" of the Drop Down By Index.
There if i select the empty string i'm getting the following error
"java.lang.NullPointerException "
How to resolve this issue.
Thanks in advance.
Regards,
Adi.

Hi Guru's,
One more problem...
The solution is working fine for removing the Empty row from the drop down by index, but when i select some thing in the dropdown box it is always pointing to the First row only???
Why it is behaving like that??/
Thanks in adavance.

Adi

How to add customized value to drop down by index binded to model attribute

i have to Ui element Drop down by index to which i have binded model attribute for populating the values, now i want to add a customized value to it like "choose all".
how can i do this ??
Thanks and regards,

Create a value node similar to model node. In value node you can add element at the index wherever you want to:
wdContext.node<nodename>().addElement(<index>,<element>);

Drop Down by Index in Table

Hi
I wish to have a drop down by index field in my table but only in certain cells in one particular row.
Once the value has been chosen I wish to then colour the two cells above the drop down.
Is this possible?
Regards
Ian

Hello Ian,
if the coloring was you only requirement, then there won't be a different between the ALV and the standard table in terms of coding. So this requirement should make the difference. Using ALV vs. standard table is usually decided on additional factors, like if users would like to use the additional options provided by ALV.

Drop down by index in table cell

Hello
I need for one column in table to have a drop down.
I have the the following context:
node: Zsi_Profile_TyperdvZish_Available_Timeslots_S_Rfc
subnode: X
value attribute in subnode X: a
Node X is singelton = false, selection: 0-1.
I am defined a drop down by index for one column and I want the data to come from node It_Rnpb2.
The code:
for (int i = 0; i< wdContext.nodeZsi_Profile_TyperdvZish_Available_Timeslots_S_Rfc().size();i++)
wdContext.nodeZsi_Profile_TyperdvZish_Available_Timeslots_S_Rfc().getElementAt(i);
for (int j = 0;j< wdThis.wdGetRendezVousCustomController().wdGetContext().nodeIt_Rnpb2().size();j++)
wdContext.nodeX().addElement(wdContext.createXElement());
wdContext.currentXElement().setA(wdThis.wdGetRendezVousCustomController().wdGetContext().nodeIt_Rnpb2().getIt_Rnpb2ElementAt(j).getOrgid());
The result is: for first table line a drop down with few empty lines and one of the line with the last value from It_Rnpb2, and for the other table lines drop downs just with an empty line.
How can I fix this?
Thank you

Let me change those ugly node names into shorter ones and use an array containing the drop-down items for each row. I think you get the idea.
Table data source node: "Rows"
Non-singleton child node "Items", cardinality 0:N, with attribute "Text".
String TEXTS[][] with TEXT[r][j] = text of item j in row r
/* foreach row in table */
for (int r = 0; r < wdContext.nodeRows().size(); ++r)
IRowsElement row = wdContext.nodeRows().getRowsElementAt(r);
/* foreach drop-down list item */
for (int j = 0; j < TEXTS[r].length; ++j)
    /* create item */
    IItemsElement item = row.nodeItems().createItemsElement();
    row.nodeItems().addElement(item);
    /* set item text */
    item.setText(TEXTS[r][j]);
I typed this code from memory so there might be minor errors.

Thanks...
Edited by: Rakshar on Sep 12, 2011 7:30 AM

Hi Rakshar,
1. Add an onSelect event to the Dropdown 1.
2. In the event handler get the the selected value of Dropdown 1 from the context of the same. Based on the selected value, retrieve the data to be displayed in Dropdown 2 ( for example data from a table)
3. Invalidate the context for Dropdown 2
4. Bind the data retrieved from table to the context for Dropdown 2 by using method BIND_TABLE
Let me know if you face any difficulty.

Drop down by index in webdynpro

I am using a drop down by index element in my webdynpro ABAP screen.
I populate this drop down by fetching values through a remote-enabled function module. How do i set one particular value as default after fetching these values. ?
I am getting the currency keys as the list of values and want to show a particular value when the view is first shown. How is this possible?
regards,
Priyank

Hi Priyank,
    I have the sample code where index is used.
    This code is used for radiobutton group by index.
    You can use same logic in your requirement.
data:
    text    type string,
    element type ref to if_wd_context_element,
    index   type string.
DATA:
    node_check                          TYPE REF TO if_wd_context_node,
    elem_check                          TYPE REF TO if_wd_context_element,
    stru_check                          TYPE if_start_ior=>element_check ,
    item_check_attribute                LIKE stru_check-check_attribute.
element = wd_context->get_lead_selection( ).
index = wdevent->get_string( 'INDEX' ).
Case when Overhead option is selected
navigate from <CONTEXT> to <CHECK> via lead selection
node_check = wd_context->get_child_node( name = if_start_ior=>wdctx_check ).
get element via lead selection
elem_check = node_check->get_element( ).
get single attribute
elem_check->get_attribute(
    EXPORTING
      name = `CHECK_ATTRIBUTE`
    IMPORTING
      value = item_check_attribute ).
if index EQ 2.
elem_check->set_attribute( name = 'CHECK_ATTRIBUTE' value = Abap_true ).
endif.
if index EQ 1.
elem_check->set_attribute( name = 'CHECK_ATTRIBUTE' value = Abap_false ).
endif.
Hope this answer will help you.

Drop down by index not getting set using Set Lead Selection

hi,
I am using drop down by index. The drop down has many values but i want to set index to 5 or something so that value at index 5 appears.
I have my data in dropdown and I am setting the 5th value using set_lead_selection_index in WddoInit but somehow its not working.
ANy inputs ?
or any other method to make a particular element in dropdown to appear as default element.

Hi,
You will have to use the method set_attribute.
l_node->set_attribute( exporting name = 'ATTRIBUTE' " your attribute name
value = 'VALUE' ). and the value that you wish to set
