Reading UI Tables in events

Question

Hi
just a simple question I am sure for most of you.. but could someone tell me how to read data from a Table UI within an event controller method I have created for a button.  I wish to identify which row was selected in a table and from that make further selections on the database prior to populating a new detailed table in the View.
I am populating the header table with data from select-options input from the user OK so I understand about binding contents of an internal table to the View Controller Context Element of the table defined at design time, but I need to be able to read that table in a different event than the one originally called by the selection process (by the user).
Please help.. I think this is so basic, that I cannot find it in help anywhere.
ps. sample code would be nice.
Thanks
Mark

Answer 1

Hi,
you are not receiving a table of your structure but in case of the first option
you receive a table of context elements so lt_component_header type wdr_context_element_set
this way you receive a table with references to the selected elements.
option1
DATA: node_component_header TYPE REF TO if_wd_context_node.
DATA: lt_component_header TYPE TABLE OF zcontract_header_str.
DATA: lo_element TYPE REF TO if_wd_context_node_element.
DATA: lt_selected_elements TYPE wdr_context_element_set.
lt_selected_elements = node_component_header->get_selected_elements(  ).
loop at lt_selected_elements into lo_element.
lo_element->get_static_attributes( importing static_attributes = ls_component_header ).
...perform actions on structure...
endloop.
option 2
DATA: node_component_header TYPE REF TO if_wd_context_node.
DATA: lo_element TYPE REF TO if_wd_context_node_element.
DATA: ls_component_header TYPE zcontract_header_str
lo_element = node_component_header->get_lead_selection( ).
lo_element->get_static_attributes( importing static_attributes = ls_component_header ).
