Dynamically Add Rows to GridView on Button Click with add and delete Button using C# and VB.Net in ASP.Net

Indresh helped me solve this problem on this link.

http://www.aspforums.net/Threads/133680/Hide-Delete-button-and-only-show-it-after-Add-button-is-clicked-Is-it-possible/

However, I tried to extend it by adding more GridView control IDs but it is not working correctly.

The problem is that when you click the Add button and a new row is added successfully, rather than expose the Delete button for that particular GridView control ID, all the Delete buttons for all three Gridviews are exposed. It is not how we want it to work. Any ideas what I need to change on any part of the code below to only expose the Delete button for only the GridView control ID that added the new row?
