Delete Table Control records via batch-input

Hi guys.

My situation is the following:

I've got a Table Control with two linked buttons: Insert (wich inserts a record in the TC) and Delete (wich deletes one record).

So the question is:

Is there any way i can delete ALL records in this TC via batch-input.

The main problem is that when i access the transaction i don't really know how many records has in it.

Can i do this???

Thanks in advance.
