How to add a checkbox to an ALV in WDA?

[former_member195355]

Hiya,

I need a table with a column as a checkbox within my web dynpro.

So I created a structure in the context, where the column for the checkbox is setup as type WDY_BOOLEAN:

Unfortunately in the ALV it appears as a non-editable checkbox:

Anyone know what I've done wrong?

Thanks in advance!

Hi,

To make the ALV editable, use the set_read_only( ) and set the value to abap_false.

  lr_component = wd_this->wd_cpifc_alv( ).

  lr_model = lr_component->get_model( ).

lr_model->if_salv_wd_table_settings~set_read_only( value = abap_false ).

Regards,

Kiran

Hiya,

I've added the following code and it seems to work. Could you just check and then I can close this discussion.

DATA:
       lr_alv_usage       TYPE REF TO if_wd_component_usage,
       lr_if_controller   TYPE REF TO iwci_salv_wd_table,
       lr_config          TYPE REF TO cl_salv_wd_config_table,
       lt_columns         TYPE        salv_wd_t_column_ref.

* Instantiate the ALV Component
   lr_alv_usage = wd_this->wd_cpuse_alv_table( ).

* Get reference to model
   lr_if_controller = wd_this->wd_cpifc_alv_table( ).
   lr_config        = lr_if_controller->get_model( ).

*Enable the non-read only fields to be edited.
   lr_config->if_salv_wd_table_settings~set_read_only( value = abap_false ).

Thanks!

Sorry but it wasn't working but I've now added this:

** Instantiate the ALV Component
   lr_alv_usage = wd_this->wd_cpuse_alv_table( ).
   IF lr_alv_usage->has_active_component( ) IS INITIAL.
     lr_alv_usage->create_component( ).
   ENDIF.

And it seems to work fine now.

Do you know why thsi would have been needed? Wouldn't the Web Dynpro have activated the ALV component?

Hi,

Sry, I hadn't noticed it. You need to initialize the component usage of ALV to get the model reference. Else it would return null.

Hi,

You can follow as suggested in these links.

1) you have to create a read only attribute in your table's node.

2)   lo_table_settings->set_read_only( abap_false ).

3) lo_column->set_cell_editor( lr_checkbox ).
