Check Box Validations in ABAP WebDynpro

[Former Member]

Hi All,

I am new to ABAP WebDynpro Coding, i have new requirement, in that one i have two check boxes, if i am selecting those two check boxes after that if i am clicking on SAVE button after that message need to display "Invalid Selection" and it won't save in the back end.

If i am selecting either one, i need to display message like" DATA WAS SAVED SUCCESSFULLY"

If any have any idea about this one, please help me.

Really i appreciate.

Thanks in Advance.

Thanks and Regards,

Abhiram.

Hi,

in the event handler of SAVE write the below code.

Hi,

You can get the value of the check boxes and then compare..

lo_el_resume_info->get_attribute(

EXPORTING

name = `chkbx1`

IMPORTING

value = lv_chkb1 ).

lo_el_resume_info->get_attribute(

EXPORTING

name = `chkb2`

IMPORTING

value = lv_chb2 ).

If lv_chkb1 IS NOT INITIAL AND LV_CHKB2 IS NOT INITIAL.

CALL METHOD lo_message_manager->report_error_message

EXPORTING

message_text = 'INVALID SELECTION'.

ENDIF.

IF lv_chkb1 IS NOT INITIAL OR LV_CHKB2 IS NOT INITIAL.

CALL METHOD lo_message_manager->report_success_message

EXPORTING

message_text = 'DATA SAVED SUCCUSFULLY'.

ENDIF.

if you want to add any condition of both check boxes are not checked you can write in similar way.

hi,

Follow these steps :

1. make the onAction of SAVE button.

2. In OnAction , Read both the attributes binded to checkbox : Att1 , Att2.

   DATA lo_nd_np4_number TYPE REF TO if_wd_context_node.
   DATA lo_el_np4_number TYPE REF TO if_wd_context_element.
   DATA ls_np4_number TYPE wd_this->element_np4_number.
   DATA lv_np4_checkbox LIKE ls_np4_number-np4_checkbox.
  navigate from <CONTEXT> to <NP4_NUMBER> via lead selection
    lo_nd_np4_number = wd_context->get_child_node( name = wd_this->wdctx_np4_number ).
  get element via lead selection
    lo_el_np4_number = lo_nd_np4_number->get_element( ).
Fetch the Value of Np4 Relevant checkbox *********************************
  lo_el_np4_number->get_attribute(
    EXPORTING
      name =  `NP4_CHECKBOX`
    IMPORTING
      value = lv_np4_checkbox ).

You can genereate the above code by code wizard ( control + F7 ).

Here NP4_CHECKBOX is my first att binded to checkbox.

4. Similarly read the second attribute.

5. NOw check the values of both the attributes .

 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
    .
if lv_np4_checkbox = 'X' and lv_np4_checkbox1 = 'X'.<Report message>
report message
CALL METHOD lo_message_manager->report_error_message
  EXPORTING
    message_text             = 'Invalid Selcteion'.
else.
if if lv_np4_checkbox = 'X'  or lv_np4_checkbox1 = 'X'
CALL METHOD lo_message_manager->report_success
  EXPORTING
    message_text             = 'DAta saved succesfully.
endif.
endif.

For messages , Use Code wizard ->Generate Message.

Hi,

At which part of these you are facing problem?

1. You need to do coding at the Save event handler class

2. Get the values of the check-boxes and see if they are selected.

3. display the message as per your requirement.

Hi Sharma,

Nice to see your reply, i know i need to write event on SAVE button, i am confusing how to compare two check boxes, i have two attrubtes v1 and v2,

if v1 = x and v2 = x then i need raise the exception like " invalid selection"

if not " message saved successfully"

could you please tell me the exact code in ABAP webDynpro.

Thanks and Regards,

Abhiram.

Hi,

That means you are having trouble retrieving the values of the check-boxes.

try this.

lr_node_header = wd_context->get_child_node( 'check box context' ).

lr_elem_header->get_static_attributes( IMPORTING static_attributes = <local value> ).

now compare the values of <local value>.

Hope this helps..

Regards

Prasenjit
