Getting error while setting color to table rows?

Question

Hi All
I am trying to setting colors to table rows based on dropdown value.
lv_Dropdown vaue =1 i want to set one color, 2-another color like that.
For this I create attribute CELL_DESIGN of type WDUI_TABLE_CELL_DESIGN in node, and i bind this attribute to every column celldesign property in table. and my code in on select of dropdown.
  data lr_column type ref to cl_wd_table_column.
data:obj_table type ref to cl_wd_table.
lr_column = obj_table->get_column( id = 'TABLE_WEEK1' ).
if lv_dropdown = 1.
   lr_column->set_cell_design(
cl_wd_table_column=>e_cell_design-badvalue_dark ).
endif.
lr_column->bind_cell_design( path = 'SEGMENT1.CELL_DESIGN'  ). ...Giving dump at r_colum = get_column( )
I follow correct code or not??

Sorry Sarbjeet and baskaran i am not getting,
I want to set colors to row of a table on dropdown selection. In dropdown i ahve a code like
DATA lo_nd_segment1 TYPE REF TO if_wd_context_node.
  DATA lo_el_segment1 TYPE REF TO if_wd_context_element.
  DATA ls_segment1 TYPE wd_this->Element_segment1.
  data lt_segment1 type wd_this->elements_segment1.
  DATA lv_segment TYPE wd_this->Element_segment1-segment.
navigate from <CONTEXT> to <SEGMENT1> via lead selection
  lo_nd_segment1 = wd_context->get_child_node( name = wd_this->wdctx_segment1 ).
get element via lead selection
  lo_el_segment1 = lo_nd_segment1->get_element( ).
  lo_el_segment1 = WDEVENT->GET_CONTEXT_ELEMENT( 'CONTEXT_ELEMENT' ).
get all declared attributes
  lo_el_segment1->get_static_attributes(
    IMPORTING
      static_attributes = ls_segment1 ).
DATA : lv_dropdown type string .
lv_dropdown =  ls_segment1-segment.
if lv_dropdown = 1.  SET ONE COLOR TO THAT ROW
endif.
if lv_dropdown = 2.  SET ONE COLOR TO THAT ROW
endif.
Now what should be the code in WDMODIFYVIEW method to set table row with colors.
