Hi Sandeep,

Read the context value attached to the radio button.

which so ever value is ABAP_TRUE, populate the table accordingly.

Hope this helps.

On the event handler of the save button, inside the method write the code like this...

DATA lo_nd_flag1 TYPE REF TO if_wd_context_node.
    DATA lo_el_flag1 TYPE REF TO if_wd_context_element.
    DATA ls_flag1 TYPE wd_this->element_flag1.
    DATA lv_flag LIKE ls_flag1-flag.
*   navigate from <CONTEXT> to <FLAG1> via lead selection
    lo_nd_flag1 = wd_context->get_child_node( name = wd_this->wdctx_flag1 ).

*   get element via lead selection
    lo_el_flag1 = lo_nd_flag1->get_element(  ).

*   get single attribute
    lo_el_flag1->get_attribute(
      EXPORTING
        name =  `FLAG`
      IMPORTING
        value = lv_flag ).

Here flag1 is the node and flag is the attribute, so in ur case go to the code wizard (ctrl + f7) and click on the radio button read context...there provide the name of ur radio button,,,you will get the value is say lv_flag variable.

So just read like

if lv_flag = 'X'.
* Write ur code
else.
* Write ur code
endif.

Hope it works..

Hi Sandeep,

you pls refere to View: RADIOBUTTON in web dynpro component WDR_TEST_EVENTS .

This will helps you to understand the logic behind this.

in Group1 of this screen you can see actions triggered for radio button selection.
