When a user deletes a record that decreases the number of pages on that Grid, and then they try to edit or add a record, they get stuck in the OnCancel event handler, which gets called over and over in an endless loop.
The behavior can be seen:

1. Delete item 11. The Grid will move you to page 1.
2. Try to edit or add a new item. OnCancel will fire in a loop.
3. If OnAdd and OnEdit are not defined, the loop will occur in OnUpdate and OnCancel.
