Hi Saurav,

when using table UI element, you will be binding some internal table to it. Ensure that this internal table

has a column with of type Boolean( lets call this column col_read_flag ).

When you bind the internal table to, UI element table, bind the property READ ONLY with the value in col_read_flag from the node, for all the columns of your table.

By default before displaying your table fill 'X' in columne col_read_flag for all rows in your internal table thus , entire table on UI would appear read-only when applicataion is executed.

Since you have edit button on each row, ONACTION when this button is pressed code to get the TABLE index, modify the col_read_flag value to ABAP_FALSE, thus your table row would become editable.

hi

Thanx for the answer.

Your answer is very much logical and helpful.

Could you tell me the code for the onaction i .e to read the table index and finally set the row editable ?

Hi,

To read the table index:

refer this code:

method ONACTIONONLINKCLICK .
  data: lr_element type ref to if_wd_context_element,
          lv_index type i.
 
  lr_element = wdevent->get_context_element( name = 'CONTEXT_ELEMENT'  ).
  lv_index = lr_element->get_index( ).

Refer this [thread|], look for the reply of shaik shadulla.

I hope it helps.

Hi Saurav,

node_data is the internal table thats binded to your TABLE UI ELEMENT.

data:
    node_data  type ref to if_wd_context_node,
    iindex type i,
    lv_err_count type i,
    lt type table of zst_my_regs,
    ls like line of lt.

  node_data = wd_context->get_child_node( name = if_componentcontroller=>wdctx_data ).
  if ( node_data is initial ).
    return.
  endif.

  call method node_data->get_static_attributes_table
    importing
      table = lt.

  if lines( lt ) lt 1.
    return.
  endif.

  iindex = node_data->get_lead_selection_index( ).
  
  if iindex lt 0.
    return.
  endif.
  
  read table lt index iindex into ls.
  ls-col_read_flag = abap_false.
  modify lt from ls index iindex.

node_data->bind_table ( lt ).

here in i am opening the ROW that has LEAD Selection for EDIT.

Hi Sourav,

Please go thru the code mention below to make a row editable of a table.

For this just take a attribute of type WDY_Boolean in ur node and bind the attribute to the UI Element Enable property.

Call this logic on the Action of ur Edit Button

METHOD onactiononclick .

DATA lo_nd_node TYPE REF TO if_wd_context_node.

DATA lo_el_node TYPE REF TO if_wd_context_element.

DATA lt_node TYPE wd_this->elements_node.

DATA ls_node LIKE LINE OF lt_node.

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

lo_nd_node = wd_context->get_child_node( name = wd_this->wdctx_node ).

• get element via lead selection

lo_el_node = lo_nd_node->get_element( ).

*

• get all declared attributes

lo_nd_node->get_static_attributes_table(

IMPORTING

table = lt_node ).

DATA: lv_index TYPE i.

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

lv_index = lo_el_node->get_index( ).

LOOP AT lt_node INTO ls_node.

IF sy-tabix = lv_index.

ls_node-read_only = abap_true.

ELSE.

ls_node-read_only = abap_false.

ENDIF.

MODIFY lt_node INDEX sy-tabix FROM ls_node TRANSPORTING read_only.

ENDLOOP.

CALL METHOD lo_nd_node->bind_table

EXPORTING

new_items = lt_node

set_initial_elements = abap_true.

ENDMETHOD.

hi,

in the table you have an atribute read only.bind this to an attribute some editable type wdy_boolean.

then for the edit button also you have the read only attribute.for this also bind this to the same attibute editable type wdy_boolean.

now using set_attribute set the editable value to abap_true or abap_false based on your requirement.
