deleting a row in a table control

[Former Member]

HI all,

I've table control with option as "delete row".

if i create 3 rows and i want to delete the third record but first record is getting deleted.

pls have look on the code... and suggest me...

method ONACTIONA_DELETE_ROW .

• Deleting a empty line from the node

DATA lo_nd_n_material TYPE REF TO if_wd_context_node.

DATA lo_el_n_material TYPE REF TO if_wd_context_element.

DATA ls_n_material TYPE wd_this->element_n_material.

DATA item_no TYPE zmatreq-zitem.

DATA lt_n_material TYPE wd_this->elements_n_material.

• navigate from <CONTEXT> to <N_MATERIAL> via lead selection

lo_nd_n_material = wd_context->get_child_node( name = wd_this->wdctx_n_material ).

• get element via lead selection

lo_el_n_material = lo_nd_n_material->get_element( ).

• get all declared attributes

lo_nd_n_material->get_static_attributes_table(

importing

table = lt_n_material ).

loop at lt_n_material into ls_n_material.

• if ls_n_material-a_req_type eq space or ls_n_material-a_matgrp eq space

• or ls_n_material-a_dev_centre eq space.

item_no = ls_n_material-itemno.

DELETE TABLE lt_n_material from ls_n_material.

exit.

endif.

endloop.

lo_nd_n_material->bind_table( lt_n_material ).

• Deleting a empty line from the node

endmethod.

Hi,

Try to use remove_element( ) method.

Refer the following threads:

Hi Suprith,

Following the way you can delete the selected row in table control. Here Node_Sumit is reference to Node bound to table control.

data:

Node_Sumit type ref to If_Wd_Context_Node,

Elem_Sumit type ref to If_Wd_Context_Element,

Stru_Sumit type If_V_Main=>Element_Sumit .

• navigate from <CONTEXT> to <SUMIT> via lead selection

Node_Sumit = wd_Context->get_Child_Node( Name = IF_V_MAIN=>wdctx_Sumit ).

• @TODO handle not set lead selection

if ( Node_Sumit is initial ).

endif.

• get element via lead selection

Elem_Sumit = Node_Sumit->get_Element( ).

• @TODO handle not set lead selection

if ( Elem_Sumit is initial ).

endif.

• alternative access via index

• Elem_Sumit = Node_Sumit->get_Element( Index = 1 ).

• @TODO handle non existant child

• if ( Elem_Sumit is initial ).

• endif.

• get all declared attributes

Elem_Sumit->get_Static_Attributes(

importing

Static_Attributes = Stru_Sumit ).

node_sumit->get_lead_selection( receiving element = elem_sumit ).

node_sumit->remove_element( exporting element = elem_sumit ) .

I hope, this will help your cause.

hi,

On the click of Del button do the following :

1.Use below code to get the index of row selected in table.

2. Further delete the records from internal table before binding.

3. Bind the node with the table.

DATA: lv_index TYPE i.

lo_el_cn_node = wdevent->get_context_element( name = 'CONTEXT_ELEMENT' ).

lv_index = lo_el_cn_node->get_index( ).

Thanx.

Hi,

after selected your row try as follows:

data node type ref to if_wd_context_node.

data elem_part type ref to if_wd_context_element.

data table_data type if_tab_second=>elements_part_func.

data table_line type if_tab_second=>element_part_func.

data line_index type i.

data line_index_str type string.

node = wd_context->get_child_node( 'PART_FUNC' ).

elem_part = node->get_element( ).

if ( elem_part is initial ).

exit.

endif.

call method elem_part->get_index

receiving

my_index = line_index.

• Delete selected record

call method node->get_static_attributes_table

importing

table = table_data.

delete table_data index line_index.

node->bind_table(

new_items = table_data

set_initial_elements = abap_true ).
