How to activate or re enable DELETE Option in Right Click in any page?

Hi,

I have a list page , where in order to disable the Standard DELETE BUTTON on TOP Left of PAGE. I have set the DeletionAllowed =No in the property of page.

When the page is in RUN Mode,Since the standard DELETE option is disabled. when i click any record (ROWS) and right-Click(using Mouse), it is showing all option except DELETE Option (which is disabled due to setting above).

Now my doubt is , can't we enable the DELETE option in RIGHT Click of mouse in list page? is there is any way to achieve the same, other that property setting?

Please suggest!
