+:Tree view removal issues:
+
+ Beside simple single level row removal, we also have to be aware of rows with children and perhaps whole hierarchy of children. We have already mentioned on previous pages, that if you remove a parent row that has a hierarchy of children, it too will be removed, i.e. removing a parent that has children, and grand children, all these descendants, as well as any of their descendants will also be removed. Normally, you will not have to wary about rows that have children, however if you have created some dependencies between the rows such as running totals this may become an issue. Shortly we will see the example where such relationships exist in the form of running totals.
