Alternatively, does your partial class have a constructor which is being called? EDIT: Okay, so presumably this is being used in a particular page or form - can you add it after the I am using the designer to create a typed dataset with a data table and table adapter. The Data Table partial class does allow you to override End Init however I can't see how to access the related Table Adapter from the Data Table.// Assumes that connection is a valid Sql Connection object.
