Inputfield values while using tableview & iterator


I'm using the MVC pattern for my BSP application.

I'm displaying data obtained from a DB table in a tableview. 2 columns need to have editable fields for user input which will then be saved in a custom table.

I managed to display the table data and get the 2 columns as editable using an iterator and overwriting the IF_HTMLB_TABLEVIEW_ITERATOR~GET_COLUMN_DEFINITIONS method.

I'm also able to get data about which row that was selected in the tableview event on do_handle_event.

However, I'm unable to access the data that is entered in the 2 editable fields.

I have gone through Brian's blog on tableview but couldn't find info on how to read data from the editable columns (especially in the MVC scenario).

I have tried every possible way I could think of but I guess I'm missing something very basic.

Could someone please help?

    This is a bit tricky the first time around.

    1 of the easiest ways is to read the form field value like a normal form field on your page, the key is to know how the field is called.

    [controller name]_[tableview name]_[row index]_[cell]

    I have a View called data and in that view I have a tableview called flighttab and I want to read the value for the selected row which 5 and the cell 7 and 8

      data: lt_1 type string,
            lt_2 type string.
      lt_1 = request->get_form_field( name = 'data_flighttab_5_7' ).
      lt_2 = request->get_form_field( name = 'data_flighttab_5_8' ).

    So a quick CONCATENATE command with the selectedRowIndex value and you are all set to go 😊

    Hi Vivek,

    as you are using MVC you might also consider using <b>Data Binding</b>, this simplifies your life a lot!

    Have a look at the documentation, try it, if you have questions left come back again 😊

    Model" target="_blank">">Model View Controller (MVC)

    Data" target="_blank">">Data Binding

    Thanks Craig for your answer, I was able to get that working. Maximilian, I agree using a model might simplify things but unfortunately I'm at a point where there's no going back 😊

    Thanks a lot for the quick response, it was a great help!

    I have another logic issue here that I could use some help with. My tableview is a MULTILINEEDIT and finally on submitting the form, I insert details of only those rows that were selected in the tableview.

    The user can select each row, making the 2 fields editable, enter values and move on either to the next row or click the submit.

    Using the code below, i can read the 2 inputfields for all previously selected rows. Even if I get the currently selected row, the user has not yet entered values for the inputfields. Hence, I am unable to get values from the last selected row.

    IF htmlb_event IS BOUND AND htmlb_event->name = 'tableView'.

    table_event ?= htmlb_event.

    IF table_event->selectedrowindex IS NOT INITIAL.

    rowselection = table_event->selectedrowindex.

    srit = table_event->prevselectedrowindextable.

    • Append current row to selection if previously not included

    READ TABLE srit WITH TABLE KEY TABLE_LINE = rowselection


    IF sy-subrc <> 0.

    APPEND rowselection TO srit.


    LOOP AT srit INTO ls_row.

    READ TABLE salineitem INDEX ls_row INTO wa_salineitem.

    ...concatenate row no.

    ...get data

    ...and process





    Could you please let me know if you'll have any other suggestion for this. Thanks once again!

    I finally got that done as well.

    I read the values for tableview fields using the form field only during submit of my form. That way, even if just one line was edited by the user, I get the data even after tableview event was called.
