Hi Rajasekhar,

Create on eattribute of type WDY_BOOLEAN and bind this to view elements REadonly property ( which you want to edit and display mode ). or Enabled proeprty. OR

If you are using Transaparent container bind TC enabled property, check as per your requirement.

Onaction of the radio button write code to edit or readonly by using SET_ATTRIBUTE method.

for ex : for edit mode... unreleased

lo_nd_segment1->set_Attribute(

name = 'CELL_DESIGN' // this is attribute of type wdYbooelan.

VALUE = ABAP_TRUE ).

released..

lo_nd_segment1->set_Attribute(

name = 'CELL_DESIGN' // this is attribute of type wdYbooelan.

VALUE = ABAP_FALSE ).

Hi Rajasekhar,

Every attribute (input ) has a property READ ONLY and in table every field if it is input has READONLY property. bind this proeprty

to attribute created of type wdy_boolean.

Why you are using 'GET_ATTRIBUTE_PROPS_FOR_NODE' i am not getting.

There is not much code here.. You ahve to create one attribute in context of type wdy_boolean.

ex : lv_readonly of type wdy_boolean. and bind this to read only property of your individual and table fields.

in your onaction of radio button..code like this..

lo_nd_segment1->set_Attribute(
name = 'READ_ONLY'        // this is attribute of type wdYbooelan.
VALUE = ABAP_TRUE ).

released..

lo_nd_segment1->set_Attribute(
name = 'READ_ONLY'   // this is attribute of type wdYbooelan.
VALUE = ABAP_FALSE ).

Cheers,

hi kris,

thanks for your valuable reply and it is working fine for individual attributes.but in my view i have displayed one alv table.

in this table i have to display one field in edit mode and remaining fields in display mode.now i am showing in that format only.

now when i press release button that edit mode field also in display mode and when i select un release option i need table in initial format means one field in edit mode and remaining in display mode.

Hi Rajasekhar,

For ALV you have to write some code like this.. follow this

lr_column = lr_column_settings->get_column( 'FIELD' ). // Field is one field you wnat to display in edit mode..

      CREATE OBJECT lr_input_field
        EXPORTING
          value_fieldname = 'FIELD'.
      lr_input_field->set_read_only( abap_true ).
      lr_column->set_cell_editor( lr_input_field ).
