Hi,
I have to bind the enabled property of input field dynamically. I can not bind the property with any attribute.
PLease suggest, and also give some dummy program if possible.

Hi Pankaj,
Declare one attribute 'BOOLEAN' in context. Bind this boolean attribute to your input field, enabled Property.
Then write this code.
DATA lo_el_context TYPE REF TO if_wd_context_element.
DATA ls_context TYPE wd_this->element_context.
DATA lv_boolean LIKE ls_context-boolean.
* get element via lead selection
lo_el_context = wd_context->get_element( ).
lv_boolean = 'X'.
* get single attribute
lo_el_context->set_attribute(
EXPORTING
name = `BOOLEAN`
value = lv_boolean ).

Hi you can bind the ready only property with an attribute dynamically as follows
Create an attribute say 'EDITABLE' type boolean
lt_columns = l_column_settings->get_columns( ) .
LOOP AT lt_columns INTO ls_columns .
CASE ls_columns-id.
WHEN 'COLUMN'.
* Create Editable cell
DATA: l_input_field TYPE REF TO cl_salv_wd_uie_input_field.
CREATE OBJECT l_input_field
EXPORTING
value_fieldname = ls_columns-id.
ls_columns-r_column->set_cell_editor( l_input_field ) .
" binding the attribute to the read only property
l_input_field->SET_READ_ONLY_FIELDNAME( 'EDITABLE' ).
ENDCASE.

Hi,
If you cannot bind the property with an attribute i suppose then that, you are also creating the Nodes and Attributes dynamically...?

Hi Pankaj,
I have a context node by name NODE & 2 attributes under it. One is for binding to the input field and the other attribute ( name ENABLED) is of type WDY_BOOLEAN. I use this attribute for controlling the editability of my input field. I specify a default value of '' i.e, readonly for this. (Check the domain values for WDUI_BOOLEAN) Now I create a button and within this button action handler I want to toggle between the input fields readonly & editable statuses. Check the code snippet below.

method ONACTIONTOGGLE_ENABLED .
data: wd_node type ref to if_wd_context_node,
lv_value type wdY_boolean.
wd_node = wd_context->get_child_node( name = 'NODE' ).
*** Read the current value in context attribute ENABLED
wd_node->get_attribute( exporting name = 'ENABLED'
importing value = lv_value ).
*** Toggle between values '' & X to toggle between the readonly & editable states of the inputfield
if lv_value = ''.
wd_node->set_attribute( exporting name = 'ENABLED'
value = 'X' ).
else.
wd_node->set_attribute( exporting name = 'ENABLED'
value = '' ).
endif.
endmethod.
