How to handle 'ENTER' Key on ALV Editable Grid on sub screen (Tabstrips)

[ravindranath_arusam]

Hello Experts ,

I have 2 questions with ALV Editable grid;

please help me if you have answers.

I created ALV grid on one of sub screens on a Tab Strip,

As soon as user types one of the columns of the ALV grid and press u2018ENTERu2019 key, it has to return corresponding details for that line.

I tried to implement this logic in ALV grid event u2018handle_data_changedu2019, but ALV internal table is not getting populated with new entry entered in the grid. but u2018double_clicku2019 event working my purpose, but user might need enter key.

and I thought I would do implement that logic in PAI event of the sub screen, u2018ENTERu2019 key not getting trigger on PAI event of the screen until cursor is on grid.

Another question 2: How do I control and not to be deleted a line on the grid (based on validation), where do I validate and by pass the delete function for a particular line, or suggest me to gray out only one line on the grid .

I would like to have delete function to work as it is ,except for some validations..

Can I implement using PAI event of the sub screen or any by ALV event.

Please suggest me..

In DATA_CHANGED event, you will get the modified row into the attribute MP_MOD_ROWS of the impoerting object ER_DATA_CHANGED. Since this MP_MOD_ROWS is the Object reference to Data, you need to have the field symbol to get the value.

  FIELD-SYMBOLS:  <lft_mod_output>  TYPE t_t_output.
  ASSIGN  er_data_changed->mp_mod_rows->* TO <lft_mod_output>.

You can get the Value of the Cell by using the method GET_CELL_VALUE of the same ER_DATA_CHANGED object and use the method MODIFY_CELL To update the value back to ALV.

To Restrict the row deletion:

When the row is deleted it is being added to Attribute mt_deleted_rows of the object ER_DATA_CHANGED. You can put the data back to the table in the DATA_CHANGE_FINISHED event. Visit this post http://help-abap.blogspot.com/2008/10/alv-disable-delete-key-on-keyboard-in.html for more information.

.... and also, the events must be registered:

ro_grid->register_edit_event( cl_gui_alv_grid=>mc_evt_enter ).
ro_grid->register_edit_event( cl_gui_alv_grid=>mc_evt_modified ).
