make title header with image in wd-alv

[Former Member]

hello,

the code

DATA: l_ref_cmp_usage TYPE REF TO if_wd_component_usage.

    l_ref_cmp_usage =   wd_this->wd_cpuse_usage_alv( ).
    IF l_ref_cmp_usage->has_active_component( ) IS INITIAL.
      l_ref_cmp_usage->create_component( ).
    ENDIF.

* Holen des ALV Configuration Model

 DATA: l_ref_interfacecontroller TYPE REF TO iwci_salv_wd_table .

* referenz auf alv component interface
 l_ref_interfacecontroller =   wd_this->wd_cpifc_usage_alv( ).
   DATA:
     l_value TYPE REF TO cl_salv_wd_config_table.

* get ConfigurationModel from ALV Component
   l_value = l_ref_interfacecontroller->get_model(
   ).
DATA: myHEADER type ref to CL_SALV_WD_HEADER.

CALL METHOD l_value->if_salv_wd_table_settings~delete_header( ).

CALL METHOD l_value->if_salv_wd_table_settings~CREATE_HEADER
  receiving
    value  = myHEADER
    .

CALL METHOD myHEADER->set_image_source( 
      value  =  '/sap/public/xy/logo.png' ).

myHEADER->set_text( 'test' ).

doesn´t show the image and my set text in the title when I test my application.

whats wrong?

I found my fault. I started the set_data-method (binding context node to alv) at last and so the settings and changes of my alv-configuration-model become deleted.

Hello,

The same code works for me as is. Can you just debug and see whether the control comes to the statements provided by you?

thanks for your answers.

DATA: myHEADER type ref to CL_SALV_WD_HEADER.

CALL METHOD l_value->if_salv_wd_table_settings~get_header
       receiving
        value = myHEADER .

CALL METHOD myHEADER->set_image_source( 
      value  =  '/sap/public/xy/logo.png' ).

myHEADER->set_text( 'test' ).

I debugged it. the text is written in myHEADER and the graphic is set but it´s not shown in internet explorer.

should I enable my changed header or something? what´s my fault?

Hello,

Just try this. Sometimes its a problem for me too. Just create a new Z-application and see if it works in that. It might not, but it is worth a try (sometimes this actualy works for me 😛 )

Neha that doesn´t reach my aim.

hmm I try additionally

CALL METHOD l_value->if_salv_wd_table_settings~set_visible_row_count
  EXPORTING
    value  = 4.

but it´s ignored too. All my settings are ignored.

I placed my code in the wddoinit of my componentcontroller and not in a view method. could this be a fault?

Hi,

try pasting it in your wdmodifyview method of the correct view

or at least but it in the wddoinit of your view

grtz,

I made it but nothing changes...the output is like pasting the code in a method of my componentcontroller

[Former Member]

Hi,

could you try to use the function get_header instead of delete_header

and use that instance to set text and image?

grtz,
