set lead selection of a dynamic node

[Former Member]

Hi All ,

I am generating a dynamic drop down by index .I want to set the lead selection of the dropdown by index , based on some

value matching from the data base table . I am using

set_lead_selection_index for the same like this :

DATA : lv_index type i .

dyn_node->set_lead_selection_index( lv_index ).

I am not able to select the index properly for my dynamic node . Can any one help me out where , I am missing , I am using the following code :

lr_container ?= wd_this->mr_view->get_element('TC_SYSTEM' ).

DATA : lv_node type string value 'SYS',

lv_sap type string .

• *internal table declaration

DATA : itab_sys TYPE STANDARD TABLE OF z2ts_systems .

• work area declaration

DATA : wa_sys TYPE z2ts_systems .

CONCATENATE lv_node wd_this->count_sys INTO lv_node.

wd_this->count_sys = wd_this->count_sys + 1.

lr_node_info = wd_context->get_node_info( ).

CALL METHOD lr_node_info->add_new_child_node

EXPORTING

name = lv_node

is_mandatory = abap_false

is_multiple = abap_true

is_multiple_selection = abap_true

is_singleton = abap_false

is_initialize_lead_selection = abap_true

is_static = abap_false

RECEIVING

child_node_info = lr_node_info.

• Get instance of new node

DATA: dyn_node TYPE REF TO if_wd_context_node.

dyn_node = wd_context->get_child_node( name = lv_node ).

• Dynamic transparent container and text edit

DATA: lo_container TYPE REF TO cl_wd_uielement_container,

lo_dropdown TYPE REF TO cl_wd_dropdown_by_idx .

• lr_attribute_info TYPE wdr_context_attribute_info,

• lr_element TYPE REF TO if_wd_context_element.

lo_container ?= wd_this->mr_view->get_element( 'TC_SYSTEM' ).

• Prepare properties of attribute & add to context node CHILD

lr_attribute_info-name = 'SYS_ID'.

lr_attribute_info-type_name = 'STRING'.

lr_attribute_info-value_help_mode = '0'.

lr_node_info->add_attribute(

EXPORTING attribute_info = lr_attribute_info ).

lr_element = dyn_node->create_element( ).

dyn_node->bind_element( new_item = lr_element

set_initial_elements = abap_false ).

wd_this->count = wd_this->count + 1.

dd_indx_id = 'DD_1'.

CONCATENATE dd_indx_id wd_this->count INTO dd_indx_id.

CONCATENATE lv_node '.SYS_ID' INTO LV_SAP.

lo_dropdown = cl_wd_dropdown_by_idx=>new_dropdown_by_idx(

bind_texts = LV_SAP

id = dd_indx_id view = wd_this->mr_view ).

• append initial line to internal table

APPEND INITIAL LINE TO itab_sys .

• populating internal table

SELECT *

FROM z2ts_systems

APPENDING TABLE itab_sys.

• bind internal table with dynamic node

dyn_node->bind_table( itab_sys ) .

DATA lv_sysid TYPE Z2TS_SYSID1.

*

select single SYS_ID from z2ts_usersys into

lv_sysid where userid EQ WD_COMP_CONTROLLER->G_EDIT_USERID

AND

role_id EQ wd_comp_controller->G_EDIT_ROLEID

AND site_id EQ wd_comp_controller->G_EDIT_SITEID and

count1 EQ wd_this->count1 .

DATA : lv_index type i .

clear wa_sys.

LOOP AT itab_sys INTO wa_sys.

IF wa_sys-SYS_ID = lv_sysid.

lv_index = sy-tabix.

ENDIF.

clear wa_sys.

ENDLOOP.

dyn_node->set_lead_selection_index( lv_index ).

cl_wd_matrix_head_data=>new_matrix_head_data( element = lo_dropdown ).

lo_container->add_child( lo_dropdown ).

Thanks in advance
