Hi,

FOR GETTING DROP DOWN GENERALLY WE DO THE FOLLOWING.

1) CHOOSE THE FIELD IN ALV WHERE WE HAVE TO GIVE THE DROP DOWN....

2)TO POPULATE VALUE IN THE DROP DOWN WE MAKE AN ATTRIBUTE value set OF TYPE  WDR_CONTEXT_ATTR_VALUE_LIST

Remember here that this node is simply used because we have to populate value in the drop down it will not  be used for binding it with any other attribute.

You can check the following code:

data: lr_col type ref to CL_SALV_WD_COLUMN,

lr_dropdown type ref to cl_salv_wd_uie_dropdown_by_key.

lo_value = lo_interfacecontroller->get_model( ).

lo_value->if_salv_wd_table_settings~set_read_only( abap_false ).

lr_column = lo_value->if_salv_wd_column_settings~get_column( id = 'Name of the alv column' ).

create object lr_dropdown exporting selected_key_fieldname = 'Name of the alv column' ..

lr_column->set_cell_editor( lr_dropdown ).

data: lt_valueset type table of wdr_context_attr_value,

ls_valueset type wdr_context_attr_value,

lr_node type ref to if_wd_context_node,

lr_nodeinfo type ref to if_wd_context_node_info.

lr_node = wd_context->get_child_node( 'CTX_VN_ALV_TABLE' ).

lr_nodeinfo = lr_node->get_node_info( ).

* navigate from <CONTEXT> to <CTX_VN_ALV_TABLE> via lead selection

  LO_ND_CTX_VN_ALV_TABLE = WD_CONTEXT->GET_CHILD_NODE( NAME = WD_THIS->WDCTX_CTX_VN_ALV_TABLE ).

* get element via lead selection

  LO_EL_CTX_VN_ALV_TABLE = LO_ND_CTX_VN_ALV_TABLE->GET_ELEMENT( ).

* @TODO handle not set lead selection

  IF LO_EL_CTX_VN_ALV_TABLE IS INITIAL.

  ENDIF.

  CALL METHOD LO_ND_CTX_VN_ALV_TABLE->GET_STATIC_ATTRIBUTES_TABLE

    IMPORTING

      TABLE = LT_ALV.

*append ls_valueset to lt_valueset.

ls_valueset-value = 'First value'.

ls_valueset-text = 'First value'.

append ls_valueset to lt_valueset.

ls_valueset-value = 'Second value'.

ls_valueset-text = 'Second value'.

append ls_valueset to lt_valueset.

lr_nodeinfo->set_attribute_value_set(

exporting

name = 'TYPES'

value_set = lt_valueset

).

Vyshnavi, I hope this feature is not yet included.. only thing is after selecting we can do the operation, when we click on dropdown, there is no option / event to trigger..

And just have a look on Suggest Values property of InputField, if suits, you can..

Hi,

Refer to the below code this will highlight the value 2. I am not using the value set property of the context attribute. I have followed the example in my previous reply.

data lo_nd_drop type ref to if_wd_context_node.

  data lt_drop type wd_this->elements_drop.

  data ls_drop type wd_this->element_drop.

  lo_nd_drop = wd_context->get_child_node( name = wd_this->wdctx_drop ).

  ls_drop-index = 'Value 1'.

  append ls_drop to lt_drop.

  clear ls_drop.

  ls_drop-index = 'Value 2'.

  append ls_drop to lt_drop.

  clear ls_drop.

  ls_drop-index = 'Value 3'.

  append ls_drop to lt_drop.

  clear ls_drop.

  lo_nd_drop->bind_table( new_items = lt_drop set_initial_elements = abap_true ).


* Setting the second value as default.

  call method lo_nd_drop->set_lead_selection_index

    exporting

      index  = 2

      .

HI friends thanks for the replies.

for example if i have an drop down contains the values regarding the plant.

drop down : 1000

                   2000

                   3000 etc.

drop down contains those values.

now i will right the select query.

select * from likp into lt_likp where vbeln = ls_likp-vbeln.

now for that particular number i should get the plant in the drop down box along with the drop down list.

suppose for that delivery number if 3000 is the plant i should get the 3000 highlighted and in the down all the remaining values how can i do it?

Step 1: Populate all the values in the 2nd dropdown as required. When you are creating a node for this dropdown, check box 'Set Lead selection' must be iniital ' '. (say : plant )

Step2 : Create an action on the first dropdown.

On action, read the value from Drop1 and get the corresponding plant.

Step3 : Get the plant dropdown table, read the value from step2 to get the index.

Now set the lead selection index .

** reading the plant table.

      context_node->get_static_attributes_table(
      IMPORTING
        table = lt_plant ).

** read the table with the plant above to get the index.

** Set the lead selection index.

  context_node->set_lead_selection_index(  lf_index ).

Hi,

Refer the following link for drop down by index.

http://webdynproabap.wordpress.com/2012/07/08/drop-down-by-index/

And to highlight the value try using method set_selection_index method of the interface if_wd_context_node.
