Thank you Shivesh and Chengalarayulu for your response.
Yeah that is what i was looking for dropdown with WDR_SELECT_OPTIONS event handling. But probably not possible.
If anyone can advice on this further.....

Sounak,

Create DropDown on your static View.. and in onSelect action.. you can populate the SELECT-OPTIONS selection screen fields..

try this.. because as per my knowledge select options & dropdown together is not possible..

hope it helps you..

HI Sounak,

     Refer this link for Select Option: http://saptechnical.com/Tutorials/WebDynproABAP/SelectOptions/demo.htm

     For Drop-Down: UseDrop Down UI Element & tht will have a event. You can use it accordingly.

Hi Sounak,

If you want to set the value of your dropdown as selected you can try this:

* create local data variable to access context information

  Data: context_node type ref to if_wd_context_node.

* create table based on context structure

  Data: it_carriers type STANDARD TABLE OF if_view1=>element_DROPDOWN_CARRIERS,

          wa_carriers like line of it_carriers.

  select *

    from scarr

    into table it_carriers.

  context_node = wd_context->get_child_node( name = 'DROPDOWN_CARRIERS').

  context_node->BIND_TABLE( it_carriers ).

* Set displayed value of dropdown by index UI element.

  index = 3. "sets dropdown value to the third entry in the drop down table

  context_node->set_lead_selection_index( index = index ).

Here , this will set the third value of your dropdown as selected one.  I hope you are using dropdown by index here.

Thanks,

Hi Neha,

I am using WDR_SELECT_OPTIONS for creating the dropdown. So, i guess there is no chance of binding the values with such dropdown.
