How to check if a view is in a edit/create/delete mode ?

Question

Hello Experts,
I have a custom requirement where I have to check the mode of the view. I have some custom logic placed in ON_NEW_FOCUS event handler method of a context node class ZCL_CLASS00004U_CN02. Now I want to execute a piece of code only in the create/edit mode.
Can someone pls help me how to achieve this ? Pls help me out I am new to Web UI.

Hi,
You have to create an attribute(in attributes tab) in your context node class like the following.
OWNER     Instance Attribute     Public     Type Ref To     CL_BSP_WD_CONTROLLER
In the create_(context_node) method of the context controller class CL_ ...... _ CTXT,
Set view controller reference to your context node 
context_node->owner = owner.
Now in the ON_NEW_FOCUS method of the context node class, you can access the controller like this.
DATA: lr_controller  TYPE REF TO (give view controller class name here).
* Get view controller
  lr_controller ?= owner.
* Determine collection that shall be displayed
  IF lr_controller->view_group_context IS NOT BOUND.
  ELSEIF lr_controller->view_group_context->is_view_in_display_mode( lr_controller ) = abap_true.
  ENDIF.
