Show/Hide tabs in form via subgrid

hi all,

I have two subgrids of the same view on a entity.

subgrid 1 is -- entity A

subgrid 2 is also -- entity A

 subgrid 1 and subgrid 2 are present in a parent entity(say, entity X which has 1:N with Entity A),..

now when I click on subgrid 1 add new button the entity form opens up, but It should hide tab1 and display tab2.

and when I click on subgrid 2 add new button the entity form opens up, but It should hide tab2 and display tab1.

Note : Subgrid 1 and Subgrid 2 are from same entity

How do I achieve this .

Thanks
