Set_first_visible_row on Table using TreeByKeyTableColumn

[Former Member]

Hi All,

I'm using a Table with a TreeBYKeyTableColumn in order to display a tree.

I have coded a search function in order to find a specifc item in the tree.

and i want that once the item found , that the tree shows the item i just found.

So to do that, i search in the context , and find the item.

Put the lead selection of the item using set_lead_selection.

then , i get the lead_selection_index using : get_lead_selection_index( ) .

Then i try to position the visible row of the table on that index using : Set_first_visible_row

It seems to work , except that the visible row showed is not the right one.

For instance , get_lead_selection_index returns 4 . the lead selection is well on the 4 , but Then i call Set_first_visible_row( 4 ) . the effective visible row see in the tree could be 6 . (the lead selection staying well on 4 )

I thought it was because the way my context was filled. But i changed my code to fill the context in exactly the same order the tree is shown , but no difference.

Would you have an idea? Or somebody could explain me how Set_first_visible_row works when there is a TreeByKeyTableColum in the table.

Note, that my tree is also full expanded.

thanks in advance.

Ok, i found a solution , for whom interrested :

You have to use if_wd_tavle_method_hdnl interface.

data lwd_table type ref to cl_wd_table.

lwd_table ?= wd_this->mo_view->get_element( iv_table_name ).

data: mh type ref to if_wd_table_method_hndl.

mh ?= lwd_table->_method_handler.

mh->expand_into_element( element = io_el_tree ).

mh->make_element_visible( element = io_el_tree ).
