Working with 2 list boxes in a tableview

17 Views

Hai Friends,

I have a table view in which the first column is a dropdown listbox and second column is also another dropdown list box.

Case1: I am working with first row of the tableview

I am selecting a value say 'Q' in the the first dropdown and its corresponding values say (Q1,Q2,Q3.....) which has to be populated in the second dropdown of the same row.

Case2: I am working with second row of the tableview.

I am selecting another value say 'D' in the the first dropdown and its corresponding values say (D1,D2,D3.....) which has to be populated in the second dropdown of the same row.

I am now coming to the problem that i am facing now.

Note: i have selected Q in the first row and its corresponding values is Q1,Q2....!

When i am selecting 'D' in the second row ( D1,D2,D3...) i am getting D1,D2,D3 in the second dropdown <b>in both rows</b>.

Actually i have to keep Q and corresponding values Q1,Q2... in the first row as i have selected 'Q' in the first row allready. when i am selecting another value value D in second row , first row values should be kept as such with Q and corresponding values Q1,Q2....., and second row should be D with D1,D2,D3.....

Now i am getting

Q D1,D2,D3

D D1,D2,D3

Actually it should be

Q Q1,Q2,Q3

D D1,D2,D3

Problem i am facing is in the iterator class method IF_HTMLB_TABLEVIEW_ITERATOR~RENDER_CELL_START

when 'secondfield'.

Here i am getting values from cookie that i have set in the do_handle_event of the controller.

Given, code that i have written in iterator class method.

WHEN 'ETYSHT'.

**************dropdownlist box**************************************

IF p_edit_mode IS not INITIAL.

DATA: etysht TYPE string.

etysht = m_row_ref->etysht.

p_replacement_bee = cl_htmlb_textview=>factory( text = etysht ).

dropdownlistbox = cl_htmlb_dropdownlistbox=>factory( id = p_cell_id ).

CALL METHOD cl_bsp_server_side_cookie=>get_server_cookie

EXPORTING

name = 'COURSEGROUP_TO_COURSETYPE'

application_namespace = application_namespace

application_name = application_name

username = sy-uname

session_id = session_id

data_name = 'COURSEGROUP_TO_COURSETYPE'

CHANGING

data_value = itl_cstypenew.

GET REFERENCE OF itl_cstypenew INTO m_locid_ref.

dropdownlistbox->table = m_locid_ref.

dropdownlistbox->nameofkeycolumn = 'ETYID'.

dropdownlistbox->nameofvaluecolumn = 'ETYSHT'.

dropdownlistbox->selection = m_row_ref->etyid.

dropdownlistbox->onselect = 'click'.

p_replacement_bee = dropdownlistbox.

ENDIF.

Looking forward for your valuable suggestion.

Thanks & Regards,

Renju.
