Multi Line Item Check

Question

This seems like a simple problem but I can't find a good answer.
If I have an item that contains infinite empty records for the
user to fill in. I want to be able to check the entire item to
see if any of the instances of the item are not null. Do I have
to create a function for this or is there something is Developer
that can handle this?
null

Hi Fan,
You can try do it in 2 ways: statically & dynamically.
I will explain both of the ways to you. Suppose you have bound your table to a context node by name SFLIGHT. It contains CARRID, CONNID, FLDATE, PRICE & an attribute by name CHECK of type  WDY_BOOLEAN.
Static Method:
When you right click on your table & say "Create Binding" you select the context node as SFLIGHT & then you get the option to specify the Cell editor of the various table columns. Now go to your column CHECK and select the cell editor as "Checkbox" & name of property to be bound as "Checked". Now this would result in the column CHECK being displayed as a checkbox to you. Also the checked/unchecked values go and get stored in the boolean attribute CHECK that you had created at context level.
Dynamic Method:
Whenever you are working with dynamic ui modification you need to put your coding inside the WDDOMODIFYVIEW method. You need to basically perform the below steps to realise your functionality:
1) You need to first get the reference of the table element.
2) You then use this reference to get the reference of the desired column by specifying the column index. 3) 3) You then create an object of type checkbox & then embed it within the cell editor of the table column
Below is the coding from the method:
method WDDOMODIFYVIEW .
  data: lr_table type ref to cl_wd_table,
        lr_column type ref to cl_wd_table_column,
        lr_check  type ref to cl_wd_checkbox.
  check first_time = abap_true.
  lr_table ?= view->get_element( id = 'TABLE' ).
  lr_column ?= lr_table->get_grouped_column( id = 'TABLE_CHECK' ).
  lr_check = cl_wd_checkbox=>new_checkbox( bind_checked = 'SFLIGHT.CHECK' ).
  lr_column->SET_TABLE_CELL_EDITOR( THE_TABLE_CELL_EDITOR = lr_check ).
endmethod.
