Hide/Show subgrid when record added to Document associated view

I have a requirement of hiding a particular sub-grid until a document is added in the Associated share-point Document View.i.e

When there are no Documents in the Associated share-point document grid view a particular sub-grid should be hidden

When a document is added to the Associated share-point document grid view the same sub-grid should be shown

Please help me in solving this scenario, thanks in advance!

Thank you
