How to select all rows of a table in a view?

[Former Member]

Hi All,

In the web dynpro abap component, there is a view containing a table UI element and this table UI element contains four table columns and one master column(treebykeytablecolumn) which I am not familiar with, so can anyone tell me how to select all rows without manually expand the whole tree structure?

Thanks in advance!

Hello,

Firstly - you'll have to ensure that the node you've bound into the tree allow for multi selection.

Then - you'll need to write some code to iterate down the structure and select everything, fortunately I had one such example just at hand.

Create a method with one input parameter of node type ref to if_wd_context_node.

I'm assuming you have a recursive node with a subnode call "SUB_NODE".

Call this method passing in the top level node:

data: lo_nd type ref to if_wd_context_node.
  lo_nd = wd_context->get_child_node( name = wd_this->wdctx_root_node ).
  select_all( lo_nd ).

method select_all .

  data: lo_subnode type ref to if_wd_context_node,
        lt_elements type wdr_context_element_set,
        lo_element type ref to if_wd_context_element.

* remove lead selection
  node->set_lead_selection_index( if_wd_context_node=>no_selection ).
 
* get any sub nodes

  lt_elements = node->get_elements( ).

  loop at lt_elements into lo_element.
    lo_element->set_selected( abap_true ).
    lo_subnode = lo_element->get_child_node( 'SUB_NODE' ).
    select_all( lo_subnode ).
  endloop.

endmethod.

Good luck.

Hi Chris,

there is no child node for the root node in the view context, and the node structure is as following;

Mynode(type is node)

attribute1_id(type is attribute)

attribute2_id_parent(type is attribute, and it is the parent of attribute1_id)

and there is no recursion node here, could you please give me another suggestion to solve this problem?

Thanks.
