get_columns() method of the table

[Former Member]

Hello All,

I have a requirement to delete the selected columns.

I tried to get the columns of a table using get_columns() method.

But it is returning nothing.Even the no_of_columns() method is also returnin 0.

I have given my coding below.

Could anybody please tell me where am going wrong?

I have written in my delete action.

Data lr_table_column TYPE REF TO CL_WD_TABLE_COLUMN.

data lr_table type ref to cl_wd_table.

DATA VALUE TYPE WDUI_TABLE_COL_SEL_STATE.

view ?= wd_this->m_view.

lr_table ?= VIEW->GET_ELEMENT( 'TBL_PA002' ).

lt_columns = lr_table->get_columns( ).

data no type i.

no = lr_table->number_of_columns( ).

if lt_columns[] is not initial.

loop at lt_columns into lr_table_column.

CALL METHOD LR_TABLE_COLUMN->GET_COL_SELECTION_STATE

• EXPORTING

• CONTEXT_ELEMENT = lr_elem

• CONTEXT_NODE_PATH_NAME =

RECEIVING

VALUE = VALUE

.

endloop.

endif.

Thanks and Regards,

You have to manipulate the table using cl_salv_wd_config_table. class object., if its alv table

Rohini,

Here is what I had to do to get it to work below.  For some reason the attribute CH_COLUMNS was not populated for the wd_table.  But the CH_GROUPED_COLUMNS attribute was populated.  So I was able to use the grouped columns to get the columns.  Sounds weird, but seems to work.

  DATA wd_grp_cols TYPE cl_wd_abstr_table_column=>tt_abstr_table_column.
  DATA wd_grp_col TYPE REF TO cl_wd_abstr_table_column.

...

  wd_grp_cols = wd_table->get_grouped_columns( ).

  LOOP AT wd_grp_cols INTO wd_grp_col.
    wd_column ?= wd_grp_col.
    APPEND wd_column TO wd_columns.
    CLEAR wd_column.
  ENDLOOP.

Rohini,

I am having the same issue.  wd_table->get_columns( ) is not returning anything.  Did you find an answer to this?

Thanks,

Kenneth

Hi Rohani ,

I looked to your problem but I did not have any solution. Maybe someone help you using these classes.

But what about use ALV component? Is it possible to you to change? The ALV component has the fieldcat button and user can setup visible fields.

Best regards.
