Unable to expand drop down by index UI element
Hi,
I have got one Drop down by index in my webdynpro form and I want to bind this to backend data. For this purpose, I created one adaptive rfc model and also did all this model binding, context mapping etc.
Now my context in view looks like this :- GetDropDown_Mn (parent node) , this has got child Output_DropDown which again has two value attributes Name and Text.
This is component controller code where you bind and invalidate
__Shell__Ca_Read_Cr_Drbox_Val_Input dropdown = new __Shell__Ca_Read_Cr_Drbox_Val_Input();
wdContext.nodeGetDropDown_Mn().bind(dropdown);
wdContext.currentGetDropDown_MnElement().modelObject().execute();
wdContext.nodeOutput_DropDown().invalidate();
I then tried to bind my UI element in view with Name attribute , but when I try to run my application , the field appears as read only, kind of non editable (blocked) and I am unable to expand my dropdown.
The readonly property of UI element is false. I have hard coded one value like " Please select from drop down list " and I want the backend values to come below this. For this, I have written code to append the backend values with the hardcoded value. Now the problem is my dropdown is blocked and not able to expand ( unable to click the arrow button), and I cannot see the other values in dropdown except the hard coded value.
Can someone please help me on this.
The cardinality of context node is 1..n, selection = 0..1 and I have set Leadselection = -1.
Thanks and regards,
Sai
Hi Sai,
You can use the below code to add the please select in ur drop down in wdInit() method
wdContext.nodeVn_Node().currentVn_NodeElement().setVa_Attribute("-Please Select-");
please use the name of node as u have created in the context.
and after that please check if yoy are getting values from RFC call or not.
if you are getting the values then try to change the selection property of that node to 1..n and comment the lead selection line that you have written.
hope this will help.
Regards
Narendra

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);

Hi all,
I have a "drop down by index" UI element in my webdynpro which is bound to a value node which intern gets values from a model node. Values are visible in the drop down and also are going to the BAPI proprely.
But, I want to show an entry simillar to "Please Select" as the first entry which is visible by default and nothing should happen if user selects this entry. how can this be acheived?
Also, I want to make the selection of the drop down mandatory. I tried chaning the "state" property of the drop down to "required". It did not work.
Any pointers on these?
Thanks,
HariHi Hari,
See this thread for "Please Select":
How to add "please select " Stirng to dropdownbyindex
On action button write code for dropdown validation whether value is selected or not.
Search in SDN for sample validation code.

Drop Down BY Index Vs Drop Down By Key
What is the difference between Drop Down By Index & Drop Down By Key.
How Do we retrive What value is selected in a drop down

NileshHello 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 replyHi,
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

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.

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 KaurHi,
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 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
VijayaHi 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.

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.

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

how can i do this ??
Thanks and regards,
Aditya DeshpandeCreate 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>);

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
IanHello 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 youLet 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.

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