ALV Tree with checked checkboxes

Former Member — Mon, 21 Jul 2008 22:14:17 GMT

Hello colleagues,

I have built a ALV Tree with checkboxes.While running the ALV Tree it is no problem to retrieve all checked items from the object "CL_GUI_ALV_TREE".

(With the method GET_CHECKED_ITEMS)

But no I have the situation that some items have to checked when you START the ALV Tree. Unfortunately I do not find a method like "SET_CHECKED_ITEMS"...

Can you please help me?

Thanks a lot.

Best regards,

Rick

There are some sample programs provided by SAP on OOPS ALV.

Check it in SE38:BCALV_EDIT_05.

if it is helpful to you,then reward...

Hello colleagues,

Thanks a lot for your help, but unfortunately I have not solved the problem :-(.

It is no problem to get the information if a checkbox is check or which item is checked.

The issue is, that I do not find out how to check a checkbox at the beginning of starting a report.

If I take you example report BCALV_EDIT_05, it is not possible to check a checkbox before running this report. It is only possible to check the checkboxes during running.

Best regards,

Rick

Hi,

Try this..

there is a proctected method UPDATE_CHECKED_ITEMS..using which you can use set the check box..

To call this method in your program..do the following..

Create a z class in your program by Inheriting the ALV TREE class CL_GUI_ALV_TREE..

Then create a method in your Z class and then call the UPDATE_CHECKED_ITEMS method in that method..

Hope I am clear..

Thanks

Hello Rick

To create an entire new class for such a simple problem is an overkill. Take the sample report BCALV_TREE_DEMO. Routine ADD_COMPLETE_LINE adds the lines to the ALV tree containing the checkbox. Here you have to add a single statement:


*&---------------------------------------------------------------------*
*&      Form  add_cmplete_line
*&---------------------------------------------------------------------*
*       add hierarchy-level 3 to tree
*----------------------------------------------------------------------*
*      -->P_LS_SFLIGHT  sflight
*      -->P_RELEATKEY   relatkey
*     <-->p_node_key    new node-key
*----------------------------------------------------------------------*
form add_complete_line using   ps_sflight type sflight
                               p_relat_key type lvc_nkey
                     changing  p_node_key type lvc_nkey.

  data: l_node_text type lvc_value.

* set item-layout
  data: lt_item_layout type lvc_t_layi,
        ls_item_layout type lvc_s_layi.
  ls_item_layout-fieldname = tree1->c_hierarchy_column_name.
  ls_item_layout-class   = cl_gui_column_tree=>item_class_checkbox.
  ls_item_layout-editable = 'X'.
  ls_item_layout-chosen   = 'X'.  " <<<< That's all.
  append ls_item_layout to lt_item_layout.

  clear ls_item_layout.
  ls_item_layout-fieldname = 'PLANETYPE'.
  ls_item_layout-alignment = cl_gui_column_tree=>align_right.
  append ls_item_layout to lt_item_layout.

  l_node_text =  ps_sflight-fldate.

  data: ls_node type lvc_s_layn.
  ls_node-n_image   = space.
  ls_node-exp_image = space.

  call method tree1->add_node
    exporting
      i_relat_node_key = p_relat_key
      i_relationship   = cl_gui_column_tree=>relat_last_child
      is_outtab_line   = ps_sflight
      i_node_text      = l_node_text
      is_node_layout   = ls_node
      it_item_layout   = lt_item_layout
    importing
      e_new_node_key   = p_node_key.
endform.                               " add_complete_line

Of course you need to add your logic which nodes should be marked and which not.

Uwe
