Hello Ganesh,

just add parameter CONTEXT_ELEMENT of type IF_WD_CONTEXT_ELEMENT to the action handler. It

contains a pointer to the currently selected context element. From it, you can get the index.

Best regards,

hello Thomas,

thanks for ur reply ,

i had added tat parameter CONTEXT_ELEMENT of type IF_WD_CONTEXT_ELEMENT to the action handler.

It's giving the index but my requirement is to fetch the index of the parent node for this current node

this context_element gives the index value of this node level only not its parent node.

Ganesh

Hello Ganesh,

in that case, just call

  lr_node_tmp = context_element->get_node().
  lr_parent_element = lr_node_tmp->get_parent_element().
  lr_parent_node = lr_parent_element->get_node().

Best regards,

Thomas
