How to create a dropdown in Web Dynpro

Hi,
I just wanted to know how to create a dropdown box.
Actually I am using a webservice and on the view I have to create a dropdown box with 4 values inside it.Also I have to map dat same field with one of the fields in the webservices request node.Is this possible???

Hi,
You can create Dropdown in two ways,
1. Create a simpleType.(DictionariesLocal dictonarysimpleTypes)
2. Go to enumeration , and add the data.
3. Create a context and in the property of the context , choose select and select the local dictionary and select the one which you have created.
4. You can create a DropDownKey and map to the context.
Dropdown by Index.
1.) Take DropDownByIndex UI Element in the Layout Tab.
2.) Take One ValueNode Named "Employee" in the Context.
3.) Take One Value Attribute Named "Id" for the Node "Employee".
4.) Bind "Employee.Id" to the texts Property of the DropDownByIndex.
5.) Set the "Employee" Node Properties in the Context Tab as
a.) Cardinality --> 0..n
b.) Selection --> 1..1
c.) Singleton --> True
6.) Write the Below Code in the Implementation Tab.
IPrivate<View Name>.IEmployeeElement empEle;
for(int i=0;i<3;i++)
empEle = wdContext.createEmployeeElement();
empEle.setId("Emp Id "+i);
wdContext.nodeEmployee().addElement(empEle);

How to Create a DropDown Box in a Selection Screen.

Hi,
I have a question. i.e, How to create a dropdown box in a Selection Screen. Could you please assist me.
Thanks & Regards
Sathish Kumar

hi satish,
The following can assist u to create a drop down ....
Drop down list box can be created in a dialog screen(SE51) as well as selection screen.
The sap list box allows to select a value from the list but we cannot enter our own value in the list box .The value list that will be displayed consists of two
fields TEXT field of TYPE 80(C) and internal KEY field of TYPE 40(C).
In screen painter to create a input/output field into list box we use
'L" as a value for dropdown attribute for the i/o field.
In screen painter to determine the type of method that will be used to fill the value
list we use the attribute value list.
If it is blank the value list will be filled by the first column of the input help assigned to the screen field.This input help can be defined in the ABAP Dictionary, on screen using SELECT,VALUES screen statements or in event POV (PROCESS ON VALUE-REQUEST ) and the input help that will be passed to the field should consists of 2 columns ,the key column is filled automatically by the system.SAP recommends value list field should be blank.
or
The value can be 'A' meaning that the value list will be filled in the event PBO(PROCESS BEFORE OUTPUT) or before the screen is displayed.In this method we use function module VRM_SET_VALUES to fill the values and pass it to the i/o field.
If a function code is attached to the list box the selection of a value triggers a PAI
otherwise PAI will not trigger.
Example
Dropdown list boxes
REPORT DEMO_DYNPRO_DROPDOWN_LISTBOX.

DATA: NAME TYPE VRM_ID,
      LIST TYPE VRM_VALUES,

How to Create adf table from java bean

Hi,
How to Create adf table from java class (Not from ADF BC).
Thanks
Satya

@vlsn -- you have to follow what shay said.
Do the following in Model layer ::
create a table property java class with your columns setters and getters like :
*public class gridProps {*
private int sno;
private String orderNum;
*public void setSno(int sno) {*
this.sno = sno;
*public int getSno() {*
return sno;
*public void setOrderNum(String orderNum) {*
this.orderNum = orderNum;
*public String getOrderNum() {*
return orderNum;
Create another table java class which will populate the values to your column values and return the collection :
*public class gridPopulate {*
private List<gridProps> gridValues ;
*public List<gridProps> setToGrid(ArrayList<ArrayList> valuesToSet) {*
*if (valuesToSet == null) {*
return gridValues;
gridValues = new ArrayList<gridProps>();
if(btnValue.equals("completeBtn"))
return gridValues;
for(ArrayList<String> tempArr:valuesToSet)
gridProps gp = new gridProps();
gp.setSno(Integer.valueOf(tempArr.get(0)));
gp.setOrderNum(tempArr.get(1));
return gridValues;
Right click gridPopulate class and create this as data control.This class will be seen in Data control list.Under this data control,Drag the grid property collection(created earlier) to your page.Then execute your binding(gridPopulate) according to your logic.

You don't do that using Java.

Hi Kumar,
If you are using EP7.0, there is no calendar UI element in webdynpro development. There is only date navigator UI element. This is demonstrated in the below article.

Hi!
I would like to create a DVD menu that offers two languages. So the first page gives two options: Language 1 and Language 2. Then depending on which language you choose, you go to a menu that proposes different videos and a photo slideshow.
Regardless on which language button you click on initially, you get the same content but in different languages.
I've been looking at Premiere's templates, which I can certainly customize, but I really don't see how to create the double menu. Does anybody have an idea?
Put the video with the first language on the timeline followed by the video with the second language. Use chapter markers so you can have each video as a chapter in the menu.
I use Premiere Pro, so I can't give more specific directions. Perhaps somebody like ATR will chime in.
Also, I have another question: can I put videos from different projects in the same DVD with Premiere or must all of the videos that go into the DVD be in the same project?
Thank you very much!!!

They must be in the same project.
