Strongly typed dataset Null Values Causes Exception
I got a table that has columns that are int type that allow for nulls. I used VS2005 dataset designer to create strongly typed dataset. When I retrieve rows that have null values in those columns an exception is thrown.
Has anybody got a workaround to this. I was thinking of changing type to string since in VS that is the only type I can set it not to throw exception then in my BLL convert it to nullable(of Integer).
Any ideas would certainly help.
Thank you
Rick

Have you tried typing the columns as Nullables?

Well,
in the properties of the column in the dataset AllowDBNull is set to True.
And in SQL the column is nullable.
What exactly do u mean by "typing the columns as Nullables"?
