hi,

Use Set lead selection index method .

lo_nd->set_lead_selection_index( '5' ).

Sample code :

DATA lo_nd_cn_popin TYPE REF TO if_wd_context_node.
DATA itab TYPE wd_this->elements_cn_popin.
DATA last_row type I.
lo_nd_cn_popin = wd_context->get_child_node( name = wd_this->wdctx_cn_popin ).
lo_nd_cn_popin->get_static_attributes_table( IMPORTING table = itab ).
describe table itab lines last_row.
last_Row = last_row + 1.
lo_nd_cn_popin->set_lead_selection_index( last_row )

hi

use set_lead_selection_index for the node to set the lead selection to a particular index

DATA lo_nd_cn_processarea TYPE REF TO if_wd_context_node.
DATA itab TYPE wd_this->elements_cn_processarea.

* navigate from <CONTEXT> to <CN_PROCESSAREA> via lead selection
  lo_nd_cn_processarea = wd_context->get_child_node(
  name = wd_this->wdctx_cn_processarea ).

lo_nd_cn_popin->get_static_attributes_table( IMPORTING table = itab ).

  lo_nd_cn_processarea->set_lead_selection_index( 1 ).

here I am setting it to 1 ,

for ur specific case , u first use get_static_attributes_table to get the data of ur table control into the internal table

thn u can set it to any other index , say i , as Saurav pointed using DESCRIBE ABAP statement

this statement gives the total no of rows in ur internal table

It wud help u solve ur query

rgds,

Hi,

You can either use the SET_FIRST_VIISBLE row property or set_lead_selection of the if_wD_context_node..

Create a context attrbute for ROW and bind to this property...FIRSTVISIBLEROW

Now, on ADD handler you can set this attributes value..
