Hi Kaustav,

As per your snapshot,

1) Create two radio button groups

    Group-1 containing radio buttons

      RGP

      NGRP

     Group-2 containing radio buttons

       PO   ( Where in you need to bind the visibility of this radio button to boolean attribute)             

      NON-PO ( Where in you need to bind the visibility of this radio button to boolean attribute)

2) Now on selecting RGP radio button,set the boolean attribute visibility to ABAP_TRUE. Then two radio buttons as per your requirement will be visible.

ie.    IF   RG_RDP = 'X'. " Radio button RGP is selected.

           LO_EL_<NODENAME>->SET_ATTRIBUTE( NAME   = ' BOOLEAN ATTRIBUTE NAME'

                                                                                    VALUE = ABAP_TRUE ).

        ENDIF.

Hope this helps you.

Thanks

AFTER WRITTING THIS CODE if i not selecting anything it is showing that po and non po radio button..see below image

[Former Member]

Hi Kaustav,

AFTER WRITTING THIS CODE if i not selecting anything it is showing that po and non po radio button..see below image

Initially in WDDOINIT( ) method of that corresponding view,set the visibility of that radio buttons to abap_false i.e set its visibility to none.

Thanks

dear hawkins,

can you explain me properly..i am confused

[Former Member]

Hi Kastav,

In WDDOINIT( ) method of that view(in which you have radio buttons) set the visibility of  PO,NON-PO radiobuttons to abap_false( i.e invisibile).

Purpose : Initially  as you want to hide that radio buttons and based on your condition enable( set visibility as abap_true( visible) ) .

Thanks

Can you provide ST22 dump analysis snap shot.

Thanks

[Former Member]

yaa sure Hawkins  i am sending the attached dump error file

Hi Kaustav,

You can achieve your requirement as below

• Create 2 radio buttons RGP & NRGP  and create a transparent container TC_RADIO_RGP below  i.e. tc_radio_rgp contains the radio buttons PO & NON PO
• Now, create a context attribute VISIBLE_TC_RADIO_RGP of type WDUI_VISIBILITY and bind the property VISIBLE of tc_radio_rgp
• On select action of radio button RGP, you can set the attribute VISIBLE_TC_RADIO_RGP to '02' and the radio buttons under RGP shown.

Hope this helps you.

Rama
