Chained Dropdown in Tableview?

Hi. I currently have 2 dropdowns in my Tableview. I need to make them chained. I don't know how to trigger an event within the tableview, so that if I select an item in one dropdown, the 2nd dropdown (only for that row) is updated with new values.
I had used a blog, and am able to create the chained behavior outside of tableview (on just a plain html page)...I just can't figure out how to trigger event within tableview. Any help is much appreciated.
Oh, and my application is NOT MVC.
Thanks in advance,
Lisa

Hi Lisa,
when you rendered a column as dropdown in table view it should also have an option to trigger an event when you select one entry in that. like OnSelect of dropdown 1 - trigger a event and then handle this event to refresh the droo down 2. I am not sure if you already tried this.

Dropdown in tableview iterator doesn't show values

Hi everybody;
I'm new to BSP. I'm creating a small BSP MVC application.
I have a table with a few columns; I needed to add an extra column in which a dropdown would be shown.
I created an iterator class and implemented the following in the GET_COLUMN_DEFINITIONS in order to add the extra column:
method IF_HTMLB_TABLEVIEW_ITERATOR~GET_COLUMN_DEFINITIONS .
FIELD-SYMBOLS: <def> LIKE LINE OF p_column_definitions.
*First normal columns
APPEND INITIAL LINE TO p_column_definitions ASSIGNING <def>.
<def>-COLUMNNAME = 'CAMPAIGN_CD'.
APPEND INITIAL LINE TO p_column_definitions ASSIGNING <def>.
<def>-COLUMNNAME = 'CAMPAIGN_NM'.
APPEND INITIAL LINE TO p_column_definitions ASSIGNING <def>.
<def>-COLUMNNAME = 'COMMUNICATION_CD'.
*<def>-EDIT = 'X'.
APPEND INITIAL LINE TO p_column_definitions ASSIGNING <def>.
<def>-COLUMNNAME = 'IDCLIENT'.
*<def>-EDIT = 'X'.
APPEND INITIAL LINE TO p_column_definitions ASSIGNING <def>.
<def>-COLUMNNAME = 'CONTACT_DTTM'.
*<def>-EDIT = 'X'.
*Finally; our defined column for status dropdown
APPEND INITIAL LINE TO p_column_definitions ASSIGNING <def>.
<def>-COLUMNNAME = 'STATUS'.
<def>-TITLE      = 'Status'.
endmethod.
Then I coded the following in the render_cell_start method to create the dropdown itself:
method IF_HTMLB_TABLEVIEW_ITERATOR~RENDER_CELL_START .
DATA: lt_table TYPE TIHTTPNVP,
        ls_table TYPE IHTTPNVP.
CASE p_column_key.
    WHEN 'STATUS'.
      CLEAR: ls_table, lt_table.
      REFRESH lt_table.
      ls_table-name = 'OK'.
      ls_table-value = 'OK'.
      APPEND ls_table TO lt_table.
      ls_table-name = 'KO'.
      ls_table-value = 'KO'.
      APPEND ls_table TO lt_table.
      DATA lt_stat TYPE REF TO DATA.
      GET REFERENCE OF lt_table INTO lt_stat.
      p_replacement_bee = CL_HTMLB_DROPDOWNLISTBOX=>FACTORY(
                            id                = p_cell_id
                            table             = lt_stat
                            nameOfKeyColumn   = 'NAME'
                            nameOfValueColumn = 'VALUE'
ENDCASE.
endmethod.
The strange thing is that the dropdown is shown but no values at all. Can someone help me out?
Thanks
Kind regards,
Allan

Hi,
Yes indeed. I did not know that the table and its reference had to be declared in the attributes of the iterator.
Another question; how to set the selected value of the dropdown after choosing a value which executes an action via the event DO_HANDLE_DATA?
The right value is passed through to DO_HANDLE_DATA, but how do I have to set the dropdown to the selected value? In which event etc?
Thanks
Kind regards

Getting the selected value in tableview.

Hi friends,

Can anybody pls help me how should i catch the selected value for a particular column in tableview.
Thanks in advance.

in the cell you are rendering a dropdwonlistbox, so to read the content of the same use
data: data type ref to cl_htmlb_dropdownlistbox.
data ?= cl_htmlb_manager=>get_data( request      = runtime->server->request
                                          name         = 'dropdownListBox'
                                          id           = 'DDLB1'
      if data is not initial.
        tab1sel = data->selection.
      endif.
for id use the same id given in the interator-render_cell_start method for this

Work around for $fieldname$ replacement inside tableview

Hello All,
I hope you can help me on an issue I have. I've create a BSP but it doesn't work with any other browser except IE.
So I changed the design to design2003 to work with other browsers but the $fieldname$ replacement inside tableview is not supported.
In the eg. a user would click on 'B10' value in a cell of col. 5 row 1 as a link and this value of 'B10' would be pass as a parameter value to
display contact information for B10.
How do I capture this value in the cell of the tableview to pass to another page for data selection??
Much appreciation for any advise.

Are you using Iterator? If not use iterator. It will allow you to do the way you wanted...

Proving the Input values in a table with a dropdown and save the values

Hi Experts,
I have a requirement to create a table which is empty (in BSP)and I want to enter the values in a table, for eg: Unit , RegNo, Regvalidity date, item categories. are the coulum names.But I have to display the values in the categories column in dropdown.
Finally I enter the values in a table and select the values in a categorie column and save the values in a ztable.
Please provide me solution how to proceed with this requirement?.
Thanks ,

Hi Kiran,
For creating blank tabel in BSP use the iterator. See the beolow link for information on creating balnk lines using iterator,
http://help.sap.com/saphelp_nw04/helpdata/en/2a/31b98a35a111d5992100508b6b8b11/frameset.htm
the code in render_cell_start method of iterator class should be something like,
initially you render all cells as blank so that the blank table is created in page.
when a row is selected you render unit, reg no., reg validity date as inputfield and categories as dropdown listbox.

Between two ViewContainerUIElements want to add RadioButton & Its Events ch

Hi friends,
I have requirement using the WebDynpro JAVA that between the DropdownList and TableView I want to add Radio Button. And want to change the even accordingly.
There is a ViewContainerUIElement_A which contained the Single DropDownList and another ViewContainerUIElement_B which contained the TableView. So based on the selection of dropdown list (ViewContainerUIElement_A) displayed records in the TableView(ViewContainerUIElement_B). Dropdown and tableView are both use the Adaptive RFC Model. Which is working fine.
Now i try to modify like this :
I have created the RadioButton as per requirement, after selection of DropDownList , I am getting the radioButton values and able to select and see the change values while clicking the Radio button which is perfectly working fine but tableView is not refreshing at all.now my question is how to call the TableView(ViewContainerUIElement_B) using the Radiobutton?
So do I need to create the ViewContainerUIElement_C for RadioButton also, currently I am using the simple Radiobuton and Group for this.
Do I need to create ViewContainerUIElement_C for RadioButton also? How to link with inbound plugs with this and how to call the even.
Suggest me plz.
Thanks
Ali

Hi Suresh,
Since TableView is ViewContainerUIElement and creating dynamically so not able to see much codes here. Any Idea how to refresh the TableView using onSelect.
I already assigned one method under the OnSelect of RadioButton using that i can see the selected values as message.
Is there any way to call the Dropdown list event in the Radio Button?
Thanks
Ali

How to display data in tableview based on a dropdown filter selection

Hi All,
I have implemented a flow logic based BSP page to display the SFLIGHTS table when I open this page it displays all records in the table SFLIGHTS. I would like the set a drop down box filter on CARRID and CONNIND. Only once the user selects the CARRID and CONNID and presses on display buttont the data for that selection in the drop down box should be displayed.
Can you kindly share the code how I can put 2 drop down boxes and make the data retrieval on the page occur based on the dropdown box selection. The layout page is as below. Appreciate if you could kindly share the code to implement this.
<%@page language="abap" %>
<%@extension name="htmlb" prefix="htmlb" %>
<htmlb:content design="design2003" >
<htmlb:page>
    <htmlb:form>
      <htmlb:tableView id              = "tv1"
                       visibleRowCount = "10"
                       selectionMode   = "lineEdit"
                       table           = "<%= flights %>"
                       filter = "SERVER"
                       sort = "server"
                       iterator        = "<%= iterator %>" />
    </htmlb:form>
</htmlb:page>
</htmlb:content>
Thanks

Yeh Karen,
What i have written is that only.. ok fine i will tell you in detail ok...
first what you do is if ur wrking with MVC concept in *do request * add the code for the dropdown as
select single connid from sflights into wa_sflights.
this code will give you the coniid in the dropdown ok
if you not wrking with MVC ,if its just a Flow with page login then write the same code in Oninitialization
now if you select the connid from the dropdown and you want to display the details of the that connid in the tableview .. rite?
then in do handle event write the code when i have written before if itsnot MVC add in oninputProcessing
DATA: HTMLB_EVENT TYPE REF TO CL_HTMLB_EVENT,
W_ID TYPE STRING,
W_VARIABLE TYPE STRING,
tvdata TYPE REF TO CL_HTMLB_TABLEVIEW.
IF HTMLB_EVENT IS NOT INITIAL.
W_ID = HTMLB_EVENT->ID.
IF W_ID EQ 'dd_project_name' . ------>this is the name of the dropdown
    DATA ?= CL_HTMLB_MANAGER=>GET_DATA( REQUEST = RUNTIME->SERVER->REQUEST
                         NAME = 'dropdownListBox'
                         ID = 'dd_project_name' ).
    IF DATA IS NOT INITIAL.
      W_variable = DATA->SELECTION.
    ENDIF.
if w_variable is not initial.
select * from sflights into table lt_flights where connid eq w_variable.
endif.
now in the view you should
<htmlb:tableView id = "tv1"
visibleRowCount = "10"
selectionMode = "lineEdit"
table = "<%= lt_flights %>"
filter = "SERVER"
sort = "server" />
Hope it works fine

IC WebClient: Add Dropdown Box to TableView

Has anyone successfully added a dropdown box inside of a CRM IC WebClient table that uses a context node? If so, I would appreciate some advice! I have read Brian's blog about table view iterators, but as usual the application in CRM is slightly different.
I'm working with a custom column in the result list (Customers context) on the BuPaSelectCustomer view. I want my custom column to be editable via a dropdown box. Here's what I've done:
1) Created a custom class that implements the IF_HTMLB_TABLEVIEW_ITERATOR interface
2) Created an attribute of the Customers context class called ITERATOR that is typed as the new class in #1
3) Added the iterator attribute to the crmic:tableView
element in the page which points to the attribute defined in #2: iterator = "<%= customers->iterator %>"
4) Set edit = "TRUE" attribute in the crmic:tableViewColumn element for my new column named 'ZZSLSTATUS'
5) In the controller class SET_MODELS method:
* Create iterator for table
IF NOT iterator IS BOUND.
    CREATE OBJECT iterator TYPE ZCL_CRM_SELCUST_TV_ITERATOR
      EXPORTING
        ir_context_node = typed_context->customers.
ENDIF.
The constructor looks like this:
method CONSTRUCTOR .
gr_context_node = ir_context_node.
endmethod.
6) GET_COLUMN_DEFINITIONS looks like this:
data: wrapper type ref to cl_bsp_wd_collection_wrapper.
gv_current_line = 0.
gv_tableview_id = p_tableview_id.
* get the wrapper of the context node
wrapper = gr_context_node->get_collection_wrapper( ).
* fill the local iterator
gr_iterator = wrapper->get_iterator( ).
7) RENDER_ROW_START looks like this:
* Position on correct index
gr_iterator->get_by_index( iv_index = p_row_index ).
8) RENDER_CELL_START looks like this:
DATA: LT_RECSTAT      TYPE TABLE OF IHTTPNVP,
      LS_RECSTAT      TYPE IHTTPNVP,
      LR_COL_DROPDOWN TYPE REF TO CL_HTMLB_DROPDOWNLISTBOX.
FIELD-SYMBOLS: <TABLE> TYPE TIHTTPNVP.
* Simple 1 record table for now
LS_RECSTAT-NAME = '1'.
LS_RECSTAT-VALUE = 'Not Called'.
APPEND LS_RECSTAT TO LT_RECSTAT.
CASE P_COLUMN_KEY.
    WHEN 'ZZSLSTATUS'.
      IF NOT P_EDIT_MODE IS INITIAL.
*       Create replacement bee to show a dropdown listbox in the
*       table cell
        CREATE OBJECT LR_COL_DROPDOWN.
        LR_COL_DROPDOWN->ID                = P_CELL_ID.
        LR_COL_DROPDOWN->NAMEOFKEYCOLUMN   = 'NAME'.
        LR_COL_DROPDOWN->NAMEOFVALUECOLUMN = 'VALUE'.
        TRY.
            CREATE DATA LR_COL_DROPDOWN->TABLE TYPE TIHTTPNVP.
          CATCH CX_SY_CREATE_DATA_ERROR.
            RETURN.
        ENDTRY.
        ASSIGN LR_COL_DROPDOWN->TABLE->* TO <TABLE>.
        IF SY-SUBRC = 0.
          <TABLE> = LT_RECSTAT.
        ENDIF.
        LR_COL_DROPDOWN->SELECTION = GR_CONTEXT_NODE->GET_ZZSLSTATUS(
                                            ATTRIBUTE_PATH = ''
                                            ITERATOR = GR_ITERATOR ).
        P_REPLACEMENT_BEE = LR_COL_DROPDOWN.
      ENDIF.
ENDCASE.
Nothing happens to the cells in my column (they still appear as uneditable with their initial values) and my breakpoints aren't hit in the custom iterator class methods when the table is rendered. Any ideas?
Thanks,
Brad

Brad or anyone who could help:
I found this article very useful and tried to follow the samples. I am not very experienced in BSP and I only need to add a column to BuPaSelectCPforCustomer IC webclient tableview.
Step 1 - done.
step 2 - I am not sure I did it right. I created a custom class ZCL_CRM_IC_BUPASELCP_CN02 for CONTACTRELATION and added an attribute ITERATOR to the class.
step 3 I add this to crmic:tableView
   iterator = "<%= CONTACTRELATION->iterator %>"
   but I go compile errors like "Field iterator is unknown".
Step 4 - skip
Step 5 - I assume the controller class is the top controller which in my case is ZL_CRM_IC_BUPASELECTCPFOR_IMPL->SET_MODELS. I added this code:
     IF NOT iterator IS BOUND.
     ENDIF.
I got the same compile errors like "Field iterator is unknown".
I think I missed something somewhere. I would really appreciate it if you could shed more light on this.
Thank you so much.

TableView- bug in dropdown-Filter?

Hi @all,
maybe i am wrong but is there a bug in the dropdownFilter-Functionality for TableView?
Yesterday we installed SP49 since then my dropdown-filter doesnt filters. I check the sbspext_table ->tableviewfilter.bsp and here is the same behaviour.
Has someone similar experiences?

Hi Rainer,
you are great! This solves my problem in 100%.
By the way comes this system behaviour with SP49?
I am pretty sure that <filter>-selection = "*" works in SP48.
Thank you very much.
Thorsten
PS I tried to give you the points but i am not able to do that. There is no radiobutton, only the "solved it on my own"

Dropdown Selection : Populate Tableview

Hi all,
           We have a requirement, in which we have to make a component which is divided into 2 sections.
Section 1: Tableview is populated based on user login
(done)
Section 2: Dropdown which has 2 values
                i. My opportunities
on selecting this, a tableview should be populated displaying all oppts which are owned by the log in user
               ii. Reportee Names
on selecting this, it displays all the people reporting to the login user, and on selecting any of them should again display opportunities of that user.
If anyone has worked upon populating tableview in a component depending upon dropdown values, please help.
     Posting Example code would be of greater help.
thanks in advance,
Rohit
