To change the font color in a webdynpro page

[Former Member]

Hi,

My requirement is to change the font color of the input field after an error message is displayed.

I have tried using the setfocus it works but my requiremnt is to change the font color for eg. i entered a invalid date then the cursor should point at that field and the font color should be red.

Thanks,

Nishant

Use this to throw error message :

*   get message manager
  DATA lo_api_controller     TYPE REF TO if_wd_controller.
  DATA lo_message_manager    TYPE REF TO if_wd_message_manager.

  lo_api_controller ?= wd_this->wd_get_api( ).

  CALL METHOD lo_api_controller->get_message_manager
    RECEIVING
      message_manager = lo_message_manager
      .

*   report message
  CALL METHOD lo_message_manager->report_attribute_error_message
    EXPORTING
      message_text              = 'Error message'
      element                   = lo_el_cn_sflight
      attribute_name            = 'CARRID'
*  
      .

CARRID is my Attribute binded to input field.

lo_el_cn_sflight is my element of Node cn_sflight.

You can use Code wizard (control + F7 ) to have this code.

DATA lo_nd_cn_node TYPE REF TO if_wd_context_node.
    DATA lo_el_cn_node TYPE REF TO if_wd_context_element.
    DATA ls_cn_node TYPE wd_this->element_cn_node .
    DATA lv_attr  LIKE ls_city-ca_attr.
*   navigate from <CONTEXT> to <CN_VISIBLE> via lead selection
    lo_nd_node = wd_context->get_child_node( name = wd_this->wdctx_ca_attr).
 
*   get element via lead selection
    lo_el_cn_node = lo_nd_cn_node->get_element(  ).

 
*  set single attribute
    lo_el_cn_node->set_attribute(
      EXPORTING
        name =  `CA_ATTR`
        value = '03 ' ).
// accordingly  set the value emphasized  , header2 or header3 as u wish 

// press CONTROL +F7 , go to code wizard and select the appropriate context attribute which u want to set

when an error message is thrown then you can get attribute in red as highlighted right...

report_attribute_error.. of if_wd_message_manager...shows this right..

Try to throw error message with report_attribute_error_message and see if it works for you.

It will set focus and mark the input box as red .
