Drop down list box selected value at the top

[Former Member]

Hi all,

I am using a drop down list box with 2 possible values in a page fragment. My issue is that when the user selects the 2nd value in the drop down the event is triggered but the dropdown shows the 1st value in the top. I would like to show the value picked by the user in the top of the list. Please let me know if we can achive this functionality.

Thanks in advance.

Below is the code i am using.

<htmlb:dropdownListBox id                = "LIST"
                       nameOfKeyColumn   = "NAME"
                       nameOfValueColumn = "VALUE"
                       width             = "300"
                       selection         = "<%= doc_type %>"
                       onSelect          = "DDLB1Event" >
  <htmlb:listBoxItem key   = "IC"
                     value = "<%= otr(YP_HRPA/DOC_TYPE1) %>" />
  <htmlb:listBoxItem key   = "PM"
                     value = "<%= otr(YP_HRPA/DOC_TYPE2) %>" />
</htmlb:dropdownListBox>
<%

 CALL METHOD REQUEST->GET_FORM_FIELD

            NAME  = 'LIST'

            VALUE = doc_type.

Yes we can achieve this. But you need to use internal table in dropdownlist as show below:

<b>Onintialization</b>

   
         entry-name = 'IC'.   entry-value = 'IC Text'. 
         APPEND entry TO itab.
         entry-name = 'PM'.  entry-value = 'PM Text'.
         APPEND entry TO itab.

<b>Layout</b>

      <htmlb:dropdownListBox id                = "LIST"
                              nameOfKeyColumn   = "NAME"
                               nameOfValueColumn = "VALUE"
                               width             = "300"
                               selection         = "<%= doc_type %>"
                               onSelect          = "DDLB1Event"
                               table             = "<%= itab %>" />

<b>Page attribute:</b>

entry	TYPE	IHTTPNVP
itab	TYPE	TIHTTPNVP

<b>OnINputprocessing:</b>

CALL METHOD REQUEST->GET_FORM_FIELD
          EXPORTING
            NAME  = 'LIST'
          RECEIVING
            VALUE = doc_type.

delete itab where name = doc_type.  " This will remove selected entry from Itab.

if doc_type = 'IC' 
         entry-name = 'IC'.   entry-value = 'IC Text'. 

else.
         entry-name = 'PM'.  entry-value = 'PM Text'.

endif.

insert entry to itab index 1.

Thank you Raja for the help full suggestions.

I am having the code for the drop down in a page gragment layout and i added the itab and entry in the page attributes of the page with flow logic thats calling the page fragmnet. But when i try to use the itab in page fragment i get an error saying that the itab doesnot exist. Cant we use the variables and page attributes of a page with flow logic in a page fragment?

[raja_thangamani · Accepted solution]

The scope of the page attribute is only within the page...So you cant use page attributes in page fragement.

Thanks Raja.

Since i need this functionality in a page fragment which doesnt have the event handler, can i put the code given by you above in a page fragment all at one place?

[raja_thangamani · Accepted solution]

No you cant put the entire code in same place.I believe all evening will be handle in the Page level. So it wont work as per your functionality. why dont you add this code in page itself..

Thanks raja!

I added all the code in the page fragment and its working fine. I caoudnot use the page with flow logic as it was a standard sap delivered BSP and i am just tweaking it a little bit.
