Filling drop down list

hi,
i have two questions:
1. i have a drop down list as one of the columns in my table. i have context node having an attribute. how do i fill this drop down list.
2. once this drop down list is filled, i want to pass the value to a method when i select a value from the drop down list.
waiting for reply.
Thanks & Regards,
Ritwik.

Hi Ritwik,
Use method set_attribute_value_set of is used to set dropdown values to an attribute of a node.
DATA: lx_current_controller TYPE REF TO if_wd_controller,
lx_node_info TYPE REF TO if_wd_context_node_info,
lx_element TYPE REF TO if_wd_context_element,
ls_value TYPE wdy_key_value,
lt_value_set TYPE wdy_key_value_table,
lx_current_controller = wd_this->wd_get_api( ).
Get the Values to that need to be set as dropdown,
Build the values set internal table. by doing the below.
CLEAR ls_value.
ls_value-key = ls_t005t-ID.
ls_value-value = ls_t005t-Airine.
APPEND ls_value TO lt_value_set[].
Set the dropdown.
Get Context reference
lx_node_info = wd_context->get_node_info( ).
Get Node 'INPUT_NODE' Reference
lx_node_info = lx_node_node->get_child_node( name = 'INPUT_NODE' ).
Set the Drop down.
lx_node_info->set_attribute_value_set( name = 'CARRID' value_set = lt_value_set ).
This would build the dropdown for the attribute.
Bind this to the column that must be displayed as DD.
Set the column type as 'Drop Down'
Hope this helps.

Fill Drop down list in Interactive form

Hello.
I am trying to display multiple values form the context of an form, so not web dynpro! I am using a valuelist object for that.
When I test the form I am only getting to see the first value of my internal table and the drop down list cannot be expanded.
If I analyse the XML I see that the items are there which I want to display.
What is the cause of this, or is this only possible with Interactive form in an Web dynpro scenario (I hope not)
Regards,
Harrie Prinsen

Hi Harrie,
As per this post, I understand that you are going to use a simple ADOBE PRINT FORM which fetches data from ECC and displays it in the form...Am I right?
See, if it is going to be a Simple PRINT FORM which is NON-INTERACTIVE in nature, I dont see the need of DROP DOWN LIST in this scenario. I think that could be the reason why always the first item of the INTERNAL TABLE is displayed all the time.
If you have an INTERACTIVE SCENARIO where the user can select an option from the drop-down, then you can go with ABAP WD/JAVA WD/ISR Adobe Interactive Forms.

Populate a drop down list with data from Excel and fill in a text field, based on drop down selectio

Hi!
I have a problem with a PDF form: There's a drop down list that I populate with Excel data that I've put in an XML file through an XSD file -- no problem here. The drop down list has a data binding to the XML file, so that a choice in the drop down list can be associated with an object in the XML file. So, when I make a choice in the drop down list, a corresponding object value is fetched from the XML file and put in a text field on the form.
How to do this is described by Stefan Cameron here:
http://forms.stefcameron.com/2006/07/29/dynamic-properties/
There's a snag, though, and to describe it more clearly:
The XML file contains three types of objects: role, role number, and role cost center. Of these I use the first and the third, i.e. the role and the role cost center. The drop down list contains the roles, and when I select a role, the corresponding cost center is filled out in the text field. So far, so good!
But -- if the cost center has the same value for two or more roles, all of these roles "bounce back" into the drop down list, that is, they are all selected in the drop down list. How many of these you can see depend on the height of the drop down list -- if it's low you'll only see the first one.
If I modify Stefan Cameron's data in his example I get the same behavior, so the problem seems to have to do with how XML data are fetched.
I'm sure there's a workaround, but I can't find it! I've spent many hours browsing the web without finding anyone with a similar problem.
Any suggestions appreciated!

Although your issue is far beyond mine, I was hoping you can help me out.....
I need to create a drop down list of names which I wish to somehow link to an Excel spreadsheet.
Please let me know the steps I need to do. I've tried several things, but nothing seems to work and I'm not sure what I am doing wrong.
Thank you

Fill-In-The-Blank drop-down list in HTML5 output

I'm working in Captivate 7 (WIN) and developing for both SWF and HTML5 output, viewing courses in IE9 for Windows and Safari on iPad.
I have a quiz containing a fill-in-the-blank question, using a drop-down list to select the correct answer, however it does not display the drop-down button or function correctly in HTML5 output (see screenshot).
The issue began after updating to Captivate 7 version 7.0.1.237. The drop-down list worked prior to the update I installed recently. I'm viewing the published course locally and in the LMS, and it does not work in either.
I've not read in the help documents that drop-down list questions are an unsupported question type in HTML5, and so I'm wondering if this is a bug that needs to be reported. Has anyone encountered this issue?

Do you need scoring? There is a Scrolling Text interaction (more control, you can empty the variable and it will be displayed empty) but it is a non-interactive one, no score possible except by adding other interactive objects.

How can I get a drop-down list selection also be selected in another field with the same list but a different name?

I have a street address and a billing address. A question is posed with a checkbox — "Is the billing address the same as the street address?" If Yes is checked, the street address automatically fills the billing fields. If No is checked, the user must fill in new information. In both the street address and billing addres, the State field is a drop-down list. How can I get the drop-down list selection in the street address State also be selected in drop-down list for the billing address State?

Has anyone done this?

Hi
According to your description, since this is SQL Server forum, as Olaf Helper’s post, could you get the correct result if you execute the following query in SQL Server Manager Studio (SSMS)?
select UserName from aspnet_Users where UserId in(select FreindId from myFreinds where UserId in(select UserId from aspnet_Users where UserName = '<your typed name>'))
If you cannot get the correct result in SSMS, I recommend to check the Transact-SQL statement. Apart from the error message, we also need to know the table structure, data, join relationships between tables for further analysis.
However if there is no problem in SQL Server query, it will be an issue that regards ASP.NET and website deployment. I suggest you to post the question in the ASP.NET forums at
http://forums.asp.net/ . It is appropriate and more experts will assist you.
In addition, there is detail about listbox control in asp.net. You can review the following links:

Is it possible to show first item in a Drop down list

Is it possible to automatically display the first item in a drop down list ?
The reason I ask is ... I am generating pre-filled PDF forms using XML data files.
Whenever there is a certain type of data I am populating a drop down list for the user to review.
Currently, the user must click on the drop down to see if data is there regardless of whether there is no data at all or many data lines of data..
I would like to make it clear to the user whether or not there is any data - right awa.y
I have considered creating a display item next (like a check box or a text field ) next to the drop down and setting it to cindicate if there is data, etc -
but i thougth that I would ask if the drop down could simply be set to automatically display the first item in the list (this is the preferred functionality)
If this is not possible I can always create a check box and set it if there is any data as an indicator for the user ..
Thanks

You can do this way..
Place the code in Inititalize event with Java Script
if(DropDownList1.rawValue == null)
DropDownList1.selectedIndex = 0;
You need to check if the Dropdown has a value selected from the previous save.. If not then set the selected item to 0th index. (which is 1st one in the dropdown values)..
Thanks

Populate drop-down list in table row or repeating subform

I am currently working on an Adobe Interactive Form integrated with web dynpro ABAP. I would like to create a table or repeating subform with a number of drop-down lists populated from SAP.
I am using the Enumerated Drop-down list from the WebDynproNative menu. In my WDDOINIT method, I am populating the attributes using the set_attribute_value_set method. This is working fine when my dropdown is not in a table or repeating subform. The dropdown is populated and the selected value is returned to SAP when submitting the form. However, when I place the dropdown in a table row or a repeating subform, the dropdown is not populated.
Any ideas or suggestions?

Hi There,
I am facing problem in Dropdown lists in Subforms.
I want the region dropdown list values according to country (only for DE) dropdown list value. Both Dropdown lists are in a Subform.
For that, I have used this in EXIT event of Country Dropdown list:
if (this.rawValue == "DE Deutschland")
data.Item.IT_ITEM.DATA.ZZ_REGION.clearItems();
data.Item.IT_ITEM.DATA.ZZ_REGION.addItem("Schleswig-Holstein","1");
data.Item.IT_ITEM.DATA.ZZ_REGION.addItem("Hamburg","2");
data.Item.IT_ITEM.DATA.ZZ_REGION.addItem("Niedersachsen","3);
data.Item.IT_ITEM.DATA.ZZ_REGION.addItem("Bremen","4");
data.Item.IT_ITEM.DATA.ZZ_REGION.addItem("Nordrhein-Westfalen","5");
data.Item.IT_ITEM.DATA.ZZ_REGION.addItem("Hessen","6");
data.Item.IT_ITEM.DATA.ZZ_REGION.addItem("Rheinland-Pfalz","7");
data.Item.IT_ITEM.DATA.ZZ_REGION.addItem("Baden-Württemberg","8");
data.Item.IT_ITEM.DATA.ZZ_REGION.addItem("Bayern","9");
data.Item.IT_ITEM.DATA.ZZ_REGION.addItem("Saarland","10");
data.Item.IT_ITEM.DATA.ZZ_REGION.addItem("Berlin","11");
data.Item.IT_ITEM.DATA.ZZ_REGION.addItem("Brandenburg","12");
data.Item.IT_ITEM.DATA.ZZ_REGION.addItem("Mecklenburg-Vorpomme","13");
data.Item.IT_ITEM.DATA.ZZ_REGION.addItem("Sachsen","14");
data.Item.IT_ITEM.DATA.ZZ_REGION.addItem("Sachsen-Anhalt","15");
data.Item.IT_ITEM.DATA.ZZ_REGION.addItem("Thüringen","16");
else
data.Item.IT_ITEM.DATA.ZZ_REGION.clearItems();
It does only change first region dropdownlist value, not others because both dropdown lists are in a Subform.
Other problem is that it works only when All Country Dropdown lists are "DE". Means, first region dropdown list depends upon not only first country dropdown but also other dropdown.
My requirement is, If first country Dropdown is "DE", only first Region Dropdown list should be fill, not others. And so on.
Please provide solution that How can I change all dropdown lists of a Subform dynamically?
Waiting for reply.
Thank you

Pre-Populating Text fields from a Data drop down list using SQL Server

I'm currently trying to update some of our internal forms which are word based or a basic PDF form you fill in by yourself.
I'm connecting to our SQL server as there are databases stored there for an internal bit of software that hold information
I can use to fill in parts the form.
I have a data drop down list that is dynamically linked to the SQL databass and allows you to select a Project Number from that database, what
I want to do after this is selected is to automatically populate some text fields with the Project name, Account handler and other fields held in the
database.
I've had a look online to see if there is a solution but haven't really found anythig that is similar (although I am new to LC so may have seen it
and not realised) and my Java is non existant.
Has anyone tried this and able to point me in the right directions?
I'm using LiveCycle ES2 version 9.0.0.2 from Creative Suit 5.5 on Windows 7

RE: Using Drop-Down List in Express Application

The easiest way to do this is to define a domain for Gender that maps to
a droplist widget. ForteExpress will then automatically display the
widget in any ArrayWindow or FormWindow in which Gender appears. (I
don't think outlinefields support this widget.) There is a documented
customization for adding SQL to the domain to automatically fill it, but
we've found this to be a performance drag. What we usually do is cache
this type of list information on the client, usually by loading it into
arrays of listelement in a service object at user logon. The list is
then ready to go whenever a window needs it, and you can set the element
list of the droplist in PostOpenInit or wherever it seems appropriate.

Subject: Using Drop-Down List in Express Application
On an Express generated Form window I want to use a drop-down list to
define the list of valid values for a database field. The underlying
database field could have a datatype of either integer or character.
For example, on the database we have a Gender column defined. I want to
use a drop-down list that displays descriptions of "Male" and "Female" for
allowed database values of "M" and "F". The Gender column is updateable on
the window.
Any suggestions on the best way to do this? Would we need to do anything
different on Array windows?

To pass the selected data to a variable from the drop down list in abap wd

Hi,
I have already created a drop down list and populated it with data from table by using the node and linking it with the internal table. Now I need to know which element is selected so based on that I need to perform some function. eg. based on the selected data , i need to populate the next drop down list.
A demo code will be really helpful.
Thanks and Regards
Tenzin

Hi,
On selcting the value from the drop down, we have one event ONSELECT.
Write the code in this event.
Get the attribute value to lV_xxxxxx using get attribute.
then using that you can fill the next DDBK attribute.
method wddoinit .
data:
        lo_nd_spfli type ref to if_wd_context_node,
        lo_el_spfli type ref to if_wd_context_element,
        ls_spfli type wd_this->element_spfli.
data:
      lv_carrid LIKE ls_sflight-carrid,
         itab_carrid type wd_this->elements_spfli,
         wa_carrid type wd_this->element_spfli,
         lo_nodeinfo_spfli type ref to if_wd_context_node_info,
         lt_value_set type wdy_key_value_table,
         ls_value_set type wdy_key_value.
lo_nd_spfli = wd_context->get_child_node( name = wd_this->wdctx_spfli ).
lo_nodeinfo_spfli = lo_nd_spfli->get_node_info( ).
select carrid
    from spfli
    into corresponding fields of table itab_carrid.
if sy-subrc = 0.
    sort itab_carrid by carrid.
    delete adjacent duplicates from itab_carrid comparing carrid.
endif.
loop at itab_carrid into wa_carrid.
    ls_value_set-key = wa_carrid-carrid.
    ls_value_set-value = wa_carrid-carrid.
    append ls_value_set to lt_value_set.
endloop.
lo_nodeinfo_spfli->set_attribute_value_set( name = 'CARRID'
value_set = lt_value_set ).
endmethod.
in the event of first DDBK, write the select statement wsing where condition of lv_XXX.
and append the record as above.

Populating Drop down List in Excel Planning Layout

HI!
hopefully somebody can help me.
I have a simple planing function ( copy function: Version1 => Version2 ), Version2 the target version is a BEx Variable and a parameter of the copy planing function.
basicly i want to put a drop down list on a Excel Planing Layout to manipulate the BEx Variable (Version 2 - the target version). So that the user can fill the BEx Variable by selecting the version by the dropdown list.
In BW-BPS is quite simple -but unfortunately i dont know how it works in BW-IP.

Hello Mike,
First you create two Drop Down lists (Dimension Version, Read Mode Masterdata table) in your workbook. Now go to the Visual basic editor (alt+F11) and you will find the following code for each Drop Down list:
Public Sub DROPDOWN_22_LostFocus()
Dim lComboBoxName As String
Dim BEx1 As Object
On Error Resume Next
lComboBoxName = "DROPDOWN_22"
Set BEx1 = Application.Run("BExAnalyzer.xla!GetBEx")
Call BEx1.RaiseComboBoxChange(Parent.Name, lComboBoxName)
End Sub
Comment the last line and add a function to output the chosen value to a cell in the workbook
Public Sub DROPDOWN_22_LostFocus()
Dim lComboBoxName As String
Dim BEx1 As Object
Dim version As String
'Call Dropdown List
On Error Resume Next
lComboBoxName = "DROPDOWN_22"
Set BEx1 = Application.Run("BExAnalyzer.xla!GetBEx")
'Call BEx1.RaiseComboBoxChange(Parent.Name, lComboBoxName)
'get version
version = DROPDOWN_22.Text
'output chosen version to a cell in the workbook
Range("C801").FormulaR1C1 = version
End Sub
Now add a command range to your workbook (VAR_VALUE_1,1, <VERSION>). Thats it.
If you need further information dont hesitate to ask me!
Best regards

Drop-down list in editable ALV

Hello all,
Does anyone know how to display the values instead of the internal values when using the alias table to specify a drop-down list in an editable ALV grid ?
Apparently the BC_ALV* examples have the same problem.
thx
Pieter

Hi,
These links will help you to implement a drop down list...
http://help.sap.com/saphelp_46c/helpdata/en/9f/dbabe435c111d1829f0000e829fbfe/content.htm
Also refer the pgm:
RSDEMO_DROPDOWN_LISTBOX
BCALV_TEST_GRID_F4_HELP
Also take a look the SAP example program BCALV_TEST_GRID_EDITABLE. It has a working Drop Down List Box.
You have to fill a table of type lvc_t_drop. In this you set a handle and value for every item you want to have in a all possible drop down lists. You will later connect a sub set of this data to your grid display data by joining on this handle. You can then send this table to your ALV grid using the method SET_DROP_DOWN_TABLE. You will also want to set the DRDN_FIELD in your field catalog to the field name in your data table that will contain the handle for the values in your drop down table you want to expose. You will need to add this field to your data table.
Best Regards,
Anjali
