Introduction
In an earlier article (Implementing
ODBC in ASP .NET), we described
some issues with Microsoft's
ODBC server controls, and how to work through them.
In a nutshell, although Microsoft provided the necessary data objects, they left
out the logic required to wire these objects into .NET's new XML-based Dataset
standard. Our article described how to perform this task manually.
Although our approach works nicely, it requires a fair amount of code, particularly
for Datasets with many fields. In addition, change control can rapidly become
a problem if several Web Forms must access the same Dataset, since any structural
change to the Dataset (adding or removing a field, etc.) must be reflected
in each Data Adapter's table mappings.
