hi,

This code will set only 5 visible rows .

Bind the visiblerow count property of table with an attribute of type I.

Before binding the table with internal table write this code :

DESCRIBE TABLE t_selected_hcp LINES lv_visiblerow.

• ****** Reduce the no of visible rows *************

IF lv_visiblerow > 5.

lv_visiblerow = 5 .

ENDIF.

• * navigate from <CONTEXT> to <CN_TABLEPROP> via lead selection

lo_nd_cn_tableprop = wd_context->get_child_node( name = wd_this->wdctx_cn_tableprop_pvl ).

• get element via lead selection

lo_el_cn_tableprop = lo_nd_cn_tableprop->get_element( ).

IF lv_visiblerow > 0 .

• get single attribute

lo_el_cn_tableprop->set_attribute(

name = `CA_VISIBLEROW_PVL`

value = lv_visiblerow ).

ELSEIF lv_visiblerow = 0 .

lo_el_cn_tableprop->set_attribute(

name = `CA_VISIBLEROW_PVL`

value = -1 ).

ENDIF.

This will make sure that only 5 rows are visible and rest you have to scroll to see.

Now if you want that out of 6 rows added to the table , last 5 rows should be visible then :

Create a Context Attribute of type I "LEAD_SELECTION" and bind this to firstVisibleRow property of table .

Write this code:

• Get the number of rows in table ****

DESCRIBE TABLE it_selected_hcp1 LINES lv_count.

DATA lo_el_context TYPE REF TO if_wd_context_element.

• Set the lead selection to last row *****

lo_el_context = wd_context->get_element( ).

lo_el_context->set_attribute( name = `LEAD_SELECTION` value = lv_count ).

lo_nd_cn_entertainment->set_lead_selection_index( lv_count ).

This will work.
