Usually, when I create a typed DataSet using the Visual Studio designer,
IsColumnNameNull methods are automatically generated for each column in my
tables. However, this time these methods were not created. I can not figure
out how to get them. Any advice? Thanks.

I think that is my problem. The AllowDBNull value must have been taken when
I dragged the table definition into the designer from Server Explorer. I can
not find a way to set AllowDBNull from the Visual Studio typed dataset
designer, though. Do I need to do this directly in the XML, or am I just
missing it somewhere else?

Select the appropriate column and use the Properties window to adjust it.
Does this work?
