How to get index when i click on blue box on a table?

Hei,

I need to select the row once i click on the box on the left most side of the row. I am able to do that if i don't have a event defined. But i need to define event. Hence i am not able to select the row by clicking that button.

So i wrote the following code once i click that box and it goes into the event i have defined.

DATA lr_element TYPE REF TO if_wd_context_element.

DATA lv_index TYPE i.

DATA l_node TYPE REF TO if_wd_context_node.

" get the index of the cell

lr_element = i_event->get_context_element('CONTEXT_ELEMENT').

lv_index = lr_element->get_index( ).

But the problem is that, lr_element, is initial and hence i get a dump.

How would i programmatically select that row when i click on the box on the far left a row? Or maybe their is a table setting which i can use to make it select everytime i click on that box eventhough i have a onSelect event defined?

Any help will be appreciated.

Thanks
