Binding the new row to the top of the table

[Former Member]

Hi Friends,

i habe a table and a button called Insert Row. If I click on this button, one row will be added to the table after the last row. I didn't find a way to jump to the added row after clicking on the Insert Row button.

I habe read in one thread here in WD Forum that as a work around I can add the new row to the top of the table using BIND_ELEMENT method.

So I tried to use BIND_ELEMENT instead of BIND_TABLE like this:

*  lo_nd_table->bind_table(  new_items = lt_table
*   index = 0 ).

* to add the new line on the top
  lo_nd_table->bind_element(
  new_item = lt_table
  set_initial_elements = abap_false
  index = 0 ).

but now i get this error message:

Dynamic type conflict when assigning references

Does anyone has an Idea?

Thank you

Regards

Hi Haleh,

Give it a try with the below code snippet. I have just given it a try and it works fine:

METHOD onactioninsert .
  DATA: lr_node TYPE REF TO if_wd_context_node,
        lr_element TYPE REF TO if_wd_context_element.

 lr_node = wd_context->get_child_node( name = if_main=>wdctx_sflight ).
 lr_element =  lr_node->bind_element( set_initial_elements = abap_false
                                      new_item             = ls_data 
                                      index                = 1 ).
ENDMETHOD.

Hi Uday, hi Chitrali,

thank you both for the answers. It works now with the index = 1.

I don't know why! Actually The first line has the index 0.

have a nice day

Kind regards

Hi Haleh,

BIND_TABLE is used to add multiple rows to a context node with cardinality o-n or 1-n..

Whereas BIND_ELEMENT is used to add one row at a time to a context node...hence you need to populate a structure ls_table that you pass as an input to BIND_ELEMENT, and not lt_table .

*  lo_nd_table->bind_table(  new_items = lt_table
*   index = 0 ).
 
* to add the new line on the top
  lo_nd_table->bind_element(
  new_item = ls_table
  set_initial_elements = abap_false
  index = 0 ).

This should resolve the error you are getting.

Thanks.

Hi Chitrali,

thank you very much for your answer. This is good I corrected the lt_table to ls_table and I don't get the error message anymore.

But i don't know why, the added row is still after the last row of the table. How can i add the new row as the first row in the table, that it could be visible immediately.

thank you

Hi haleh set the index to 1. It would get displayed as the 1st row of your table.

Hi Uday,

yes I tried above to say that I did this and the new line comes on the top, even though I still don't know why!

thanks again
