I have web dynpor alv tables set up for multiple selections but not working

[Former Member]

Hi ,

I have numerous alv tables within my application and i have following the steps needed to set them up for multiple selection.

The context node selection property is set up as 0..n

I also have the modify method set up with the method call

CALL METHOD lo_value->if_salv_wd_table_settings~set_selection_mode

EXPORTING

value = cl_wd_table=>e_selection_mode-MULTI_NO_LEAD.

I also have the no lead selection option set so initially there is no entry selected

I can select one entry without a problem.

I can also select one entry and then if i use the shift button when selecting another record it will select all the records in between.

However i cant pick numerous individual records at the same time.

I try by selecting a record and the n using the control button to select a second record but it wont work.

Any ideas what i am missing or what i am doing wrong.

Any help is greatly appreciated.

Regards

Hi,

Thanks for all the help with this.

When i enter the code

lr_node = <row_data>-context_element->get_node( ).

or

lr_node = <row_data>-context_element->get_node( 'MY_ACTIVITIES' ).

• MY_ACTIVITIES is the name of the context associated with the alv table

IF i_accesstype = 'TOGGLE' AND "#EC NO_TEXT

( <row_data>-context_element->is_selected( ) = abap_true

*>>>> START OF DELETION <<<<<

OR lr_node->get_lead_selection( ) = <row_data>-context_element )."#

EC NO_TEXT

*>>>> END OF DELETION <<<<<<<

*>>>> START OF INSERTION <<<<

OR <row_data>-context_element = i_lead_selection ).

*>>>> END OF INSERTION <<<<<<

i get the error message

Incorrect arithmetic expression: Instead of

"<ROW_DATA>-CONTEXT_ELEMENT->GET_NODE(", a field, a function or "(" was

expected. expected.

Any idea what i need to resolve this

I tried the code listed above but it throws nothing but error messages

The exact code i have in my modifyview method is as follows

data lo_cmp_usage type ref to if_wd_component_usage.

data lr_config TYPE REF TO cl_salv_wd_config_table.

data lr_column TYPE REF TO cl_salv_wd_column.

data lr_link TYPE REF TO cl_salv_wd_uie_link_to_action.

data lr_column_settings type ref to if_salv_wd_column_settings.

data lr_column_header type ref to cl_salv_wd_column_header.

data lr_table_settings type ref to if_salv_wd_table_settings.

data lr_columns type ref to cl_salv_columns_table.

lo_cmp_usage = wd_this->wd_cpuse_my_act_alv( ).

if lo_cmp_usage->has_active_component( ) is initial.

lo_cmp_usage->create_component( ).

endif.

DATA lo_INTERFACECONTROLLER TYPE REF TO IWCI_SALV_WD_TABLE .

lo_INTERFACECONTROLLER = wd_this->wd_cpifc_my_act_alv( ).

DATA lo_value TYPE ref to cl_salv_wd_config_table.

lo_value = lo_interfacecontroller->get_model(

).

CALL METHOD lo_value->if_salv_wd_table_settings~set_selection_mode

EXPORTING

value = cl_wd_table=>e_selection_mode-MULTI_NO_LEAD.

lo_value->if_salv_wd_std_functions~set_aggregation_allowed( abap_true ).

lo_value->if_salv_wd_std_functions~set_group_aggregation_allowed( abap_true ).

lr_column_settings ?= lo_value.

lr_table_settings ?= lo_value.

lr_column = lr_column_settings->get_column( 'ACTIVITY_NO' ).

CREATE OBJECT lr_link.

lr_link->set_text_fieldname( 'ACTIVITY_NO' ).

lr_column->set_cell_editor( lr_link ).

lr_column = lr_column_settings->get_column( 'ACTIVITY_DESCR' ).

lr_column->set_width( '160' ).

lr_column->delete_header( ).

lr_column_header = lr_column->create_header( ).

lr_column_header->set_text( ls_dashboard_display-ACTIVITY_DESCR ).

• More code to set up individual columns *********************

lr_table_settings->set_visible_row_count( -1 ).

lr_table_settings->set_footer_visible( 0 ).

endmethod.

The code listed in the note looks completely different to what i currently have , i dont read any nodes when setting up the alv table . Am i putting the code in the wrong place?

HI,

In the MODIFYIEW the instance is created everytime when this gets triggered. try to use the FIRST_TIME attribute

such that onlyfor the first time it is called.....

Hi Lekha,

Thanks for the head up , i had a look at the other thread and i found this code

lr_node = <row_data>-context_element->get_node( ).

IF i_accesstype = 'TOGGLE' AND "#EC NO_TEXT

( <row_data>-context_element->is_selected( ) = abap_true

*>>>> START OF DELETION <<<<<

OR lr_node->get_lead_selection( ) = <row_data>-context_element )."#

EC NO_TEXT

*>>>> END OF DELETION <<<<<<<

*>>>> START OF INSERTION <<<<

OR <row_data>-context_element = i_lead_selection ).

*>>>> END OF INSERTION <<<<<<

Where exactly do i put this into my dynpro application

Should it be in the modifiy view somehere when i am setting up the alv table

HI,

I hope you can try in WDDOMODIFY VIEW and let me know if it works else

use the OSS Notes 1306538 will fix your problem.
