Hi Prabhu,
I saw the picture. I'll give you a solution similar to that using buttons.
While creating the node for the table, just add one more attribute for the button (i used boolean type). While binding make this field as button and bind the attribute to some unused property of button (I bound it to tooltip property of the button). Now on WDDOINIT I put the following code to initialize the data
method WDDOINIT .
  data: begin of stru,
          kunnr type kunnr,
          name1 type name1,
          butid type boolean,
        end of stru,
        itab like standard table of stru with key kunnr,
        node type ref to if_wd_context_node.
        node = wd_context->get_child_node( name = 'KNA1_NODE' ).
        select kunnr name1 from kna1 into corresponding fields of table itab.
        loop at itab into stru.
          stru-butid = 1.
          modify itab from stru.
        endloop.
        node->bind_table( itab ).
endmethod.
Now on the action of the button on the table. Add a code similar to the following one. Include your code for deleting from the database.
method ONACTIONDELETE_ROW .
  data: ind type i,
        itab type standard table of if_main=>element_kna1_node,
        node type ref to if_wd_context_node,
        elem type ref to if_wd_context_element.
  wdevent->get_context_element( exporting name ='CONTEXT_ELEMENT' receiving value = elem ).
  elem->get_index( receiving my_index = ind ).
  node = wd_context->get_child_node( 'KNA1_NODE' ).
  node->get_static_attributes_table( importing table = itab ).
  delete itab index ind.
  node->bind_table( itab ).
endmethod.
Now this will delete the corresponding row of which the delete button is pressed. And for delete all my previous post will work I suppose.
Hope it ll be useful for you. If you got the answer, please dont forget to close the thread.
