This is true, until you copy the control and paste it elsewhere, or copy/clone a group or card it belongs to and paste it elsewhere. The stack has an auto incrementing ID, and any time a new object is created it gets that ID, and the stack ID is incremented by 1. This is a blessing and a curse. You have to think if it as the ID of the INSTANCE of an object. For instance (no pun intended) every time a datagrid redraws, it creates all new objects, and each object gets the next ID. I think my project has IDs in the millions now.
I'm not sure if there is a limit for these IDs. When datagrids first came out, this was a discussion that was had, about what would happen if a stack eventually reached this limit. However, I think the limit is so incredibly high that it is extremely unlikely.
