Controlling visibility of ALV columns at runtime

Hi
I have an ALV column which is of type DropdownByKey. I can control the visibility of the dropdown by setting it based on another context node attribute (for e.g., 'CAT_VALUE_I_VISIBLE') which I modify at runtime. But then I want to hide the column itself based on the other context node attribute which I am not able to. Is it possible ?
I have something like this to hide the dropdown
lo_drdn_by_key->set_visible_fieldname( 'CAT_VALUE_I_VISIBLE' ).
But on the column level there is only a method like :
DATA lo_column type ref to cl_salv_wd_column.
lo_column-r_column->set_visible( cl_wd_uielement=>e_visible-none ).
Is there a possibility to control the visibility of an ALV column at runtime ?
Thanks and regards
Sukanya

Hi,
Depending upon another context attribute condition get th ecolumn ref of the alv field which you want to hide and set the visibility property to none.
data : lt_columns type SALV_WD_T_COLUMN_REF.
Get the column ref
  CALL METHOD lo_value->if_salv_wd_column_settings~get_columns
    RECEIVING
      value = lt_columns.
CALL METHOD lr_column->set_visible
        EXPORTING
          value = cl_wd_uielement=>e_visible-none.
Thanks,

  • How do I control a table's column visible in Java

    Using JDeveloper 11.1.1.4.0
    I want to control a rich tree table's column visibility programatically in Java. I've looked for syntax and do not find an example like I need. I need to directly control the column similar to how a panel collection does. The visibility of the column will be set and then the table refreshed (I've got the refresh part working), I just need to correctly reference the column. This logic will be triggered by a rowDisclosureListener that is defined as pageFlowScope. I've tried experimenting on myTable which is a RichTreeTable, but the plethora of syntax choices after "myTable." is enormous. Also, is it possible to allow the panel collection to override this logic or remove the column from its columns list?
    Thanks in advance,
    Troy

    Wow, I wish I could include a screenshot to show what is happening. My bean has somewhat similar logic, only I am trying to have my treetable show an additional column when a node of the treetable is expanded. I thought this problem might be caused by the panel collection so I tried taking it off, but it still behaves the same. I can show the column, but no header shows up for it. The original column headers stay fixed as does the data of node 0, but the subsequent (node 1) data after the first column is shifted to the right with each column added between the first column and the end column. If I do a browser refresh after expanding a node, it refreshes with the column header that was missing--strange.
    from my bean:
        public void onNodeDisclosure(RowDisclosureEvent rowDisclosureEvent) {
            boolean isCloseEvent = false;
            RowKeySet rowKeySet = rowDisclosureEvent.getAddedSet();
            //did disclosure event open a new node ?
            if (rowKeySet.iterator().hasNext()) {
                isCloseEvent = false;
                nodeLevel++;
            } else {
                isCloseEvent = true;
                nodeLevel--;
                //get the previously disclosed set
                rowKeySet = rowDisclosureEvent.getRemovedSet();

  • ALV column displays either button or text ?

    Dear collegues,
    I want to display one column in an ALV table that either displays a button (with a text on it) or displays a text (without button). The decision what of these 2 possibilites is shown should be controlled by the runtime data (eg. the WD context).
    PS: I know how to display one ALV column with only buttons or one ALV column with only text.

    Hi Christian,
    a) Is the command l_cv->set_key( 'TEXT_VIEW' ) still correct to display the icon ?
    yes there is a no show stopper to display icon.since TEXT_VIEW is a string value to populate  text/check box conditionally.
    b) What I fill into the new context field 'CELL_VARIANT' while runtime ? Should it filled with u201CTEXT_VIEWu201D to display the iconand with u201C u201C to display the button ?
    you can give either button or icon to cell_variant.Follow my code as it is .you will get the output.

  • Changing header title of column at runtime

    Hi
    I want to change the column header in an ALV table at runtime. I know how to overwrite a DDIC binding text of the column header with my own static text but I also want to know how to modify this column header text dynamically. I have a separate attribute in my context node to serve as the column header, which I can keep modifying at runtime, but the problem is to bind this attribute  to the header of the column.
    Thanks and regards

  • Controle the WD table column position Sequence

    HI All,
    How to  controle the WD table column position  (not ALV) in webdynpro as per custom requirnment.
    Column1, Column2, Column3, Column4…………
    I looked into CL_WD_TABLE to see any possibility.
    Can anyone suggest me the right one?
    Thanks
    Gopal

    Hi,
    Can we rearrange the existing columns of nodes by passing the index and column name.
    Unfortunately, No! you have to remove the column and add it.
    As I have already have a component with table need to rearrange the columns.
    Is it a standard component or custom component?
    If it is a custom component, you can rearrange by right click on column and move up/down.
    If it is a standard component, consider deleting the table( Remove Element) in enhancement mode and then create a new Table UI with specified order.  Or, create a post exit in wddomodifyview and then get the table reference and use remove_column( ) add_column( ) methods
    code snippet:
    DATA: lr_table    TYPE REF TO cl_wd_table,
           lr_abs_col TYPE REF TO cl_wd_abstr_table_column,
           lr_col     TYPE REF TO cl_wd_table_column.
      IF first_time EQ abap_true.
    * get table reference
          lr_table ?= view->get_element( id = 'TABLE ). " ID of Table UI
         CALL METHOD lr_table->remove_grouped_column
           EXPORTING
             id                = 'COL1' " column
             index             = 1      " index
           RECEIVING
            the_grouped_column = lr_abs_col.
          lr_col ?= lr_abs_col.
         CALL METHOD lr_table->add_column
           EXPORTING
             index              = 20  " new index

  • How to Pre-Select a View for ALV dashboard at runtime

    Hello Experts,
    The requirement is to pre-select 1 view initially (out of several configured) for 'All' users and disable the 'View-selection' dropdown function in a standard ALV dashboard. So whenever the dashboard loads, a particular view has to be set automatically for all users.
    I need your help for the first part, which is to always pre-set a 'View' in a standard dashboard.

  • Show image in Web Dynpro ALV column

    Hello everybody,
    I have a WD component with an ALV table bound to a context node. Works very fine so far.
    Now in the first column of the node I have put an image source (MIME object in my WD component).
    I configured the first ALV column as Link To Action and now would like to link it to the image source. My problem is that the image is not loaded in the ALV.
    This is my coding (INIT method of my view):

    fix settings for test purpose (how must I change it to get the information from the context node??)
      lo_link_to_action->set_image_height( '50px' ).
      lo_link_to_action->set_image_width( '50px' ).
      lo_link_to_action->set_image_source( 'ICE Flottenportal.jpg' ).
      lo_column->set_cell_editor( lo_link_to_action ).
    ENDMETHOD.
    Thanx a lot in advance for any help!!

    Thanks a lot for your helpful advice.
    I now found that method cl_wdr_utilities=>get_mime_path is the best way to get the path.
    But one question is still open:
    How can I retrieve my image source from the context? Do I have to read the context and then write it to the image_source attribute? Or ist there a more elegant solution?
    Thank you for any help!

    Hi Juergen,
    I found Your blog and found it  really interesting... though I was not able to use it: I (like Jun Li is asking, I guess) need to use a dynamic text, containing formatting informations (according the xhtml syntax).
    I tried to pass it to the form by an ABAP-dictionary based interface and by means of the context (in a webdynpro page), but both tries failed.
    Some suggestion will be greatly appreciated.
    Thankyou

    Doubt there is the dynamic you are seeking.
    But you may put a few overlapped columns (diff. length of course) and display/hide by passing parameters.
