Question

Answer 1

OnLeadSelect - What kind of logic do you want?  There are many different things that you could do inthe OnLeadSelect
onFilter- Generally you use IF_WD_TABLE_METHOD_HNDL~APPLY_FILTER  to perform the filter operation.
In the onFilter itself you probably just have one line of code:
wd_this->table_method_hndl->apply_filter( ).
In your WDDOMODIFYVIEW you probably have this code to capture the table_method_hndl object:
if first_time = abap_true.
  * Get reference of the table view element
  l_table ?= view->get_element( 'TABLE' ).
* Get reference to the Filter & Sorting API
  wd_this->table_method_hndl ?= l_table->_method_handler.
endif.
