Hi,

You put condition like that, if value is select then only process further.

If list box is initial through some message like, no value selected.

In your title you are asking default value?? just by setting/removing lead selection of node which you bind to list box,

you can manage this. try.

Cheers,

Hi

If you use DROPDOWNBY INDEX element, you would have binded the CONTEXT NODE with a table(dropdown values) and these are the values appear in the dropdown.

The lead selected index VALUE will be shown as default in the dropdown and you will have to set the LEAD SELECTION to the REQUIRED INDEX sothat it will be shown as default.

DATA: LD_NODE TYPE REF TO IF_WD_CONTEXT_NODE.
 
      * get the code reference
      LD_NODE = wd_context->get_child_node( 'NODE_NAME' ).
       
     * set the lead selection to make it as default in dropdown
      LD_NODE->SET_LEAD_SELECTION_INDEX( INDEX = 1 ). //where 1s as default

If you are using drop down by key check this...

Cheers,

Kris.
