Victoria and Bonnie,

When you are creating a typed dataset, the default value will not be generated in the schema, you have to add it manually. So when you add a new row to that dataset, and exception is thrown.

To add default values to the schema, open the xsd file of your dataset. (The xsd file is where you drag and drop the table to.) Click the column name which you want to set a default value to. In the properties windows, you'll see the "default" property. You can assign your default value there.
