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. Row Updating -= new Sql Row Updating Event Handler(On Row Updating); cust Adapter.There is no events part of the properties page that I can see. Sql Data Adapter cust Adapter = new Sql Data Adapter( "SELECT Customer ID, Company Name FROM Customers", connection); // Add handlers. Row Updating = new Sql Row Updating Event Handler(On Row Updating); cust Adapter. None ' Set the batch size,' ' try to update all rows in a single round-trip to the server' adapter. Add(New Data Column("Date", Get Type(Date))) table2. Row Updated, _ New Sql Row Updated Event Handler(Address Of On Row Updated) adapter. Add(New Data Column("Table One Id", Get Type(Int32))) ' copy content from table1 to table2' For Each row As Data Row In table1. New Row new Row("Table One Id") = row("ID") new Row("Name") = row("Name") new Row("Date") = row("Date") table2. Add(new Row) ' note: i have not tested following, but it might work or give you a clue' new Row. Set Modified() Next ' Execute the update' Add Handler adapter. Get Event(event Name, Binding Flags.[Public] Or Binding Flags. Declared Only) End Function ''' Public Function Add Row Updated Handler(adapter As Db Data Adapter, handler As Row Updated Event Handler) As Boolean Dim upd Event As Event Info = Get Event("Row Updated", adapter.[Get Type]()) If upd Event Is Not Nothing Then Try If handler. Method)) End If Return True Catch End Try End If Return False End Function ''' Public Function Add Row Updating Handler(adapter As Db Data Adapter, handler As Row Updating Event Handler) As Boolean Dim upd Event As Event Info = Get Event("Row Updating", adapter.[Get Type]()) If upd Event Is Not Nothing Then Try If handler. Message) End Try End With End Sub You should set the Update Batch Size property of the Sql Data Adapter to 0 (unlimited).

Add(New Data Column("Name", Get Type(String))) table2.

Otherwise, it works fine, and now I have provider-independent event handlers available from the Db Data Adapter class (which is how Microsoft should have implemented them to begin with). ''' Public Delegate Sub Row Updating Event Handler(sender As Object, e As Row Updating Event Args) Public Module Db Data Adapter Extension Sub New() End Sub Private Function Get Event(event Name As String, type As Type) As Event Info Return type.

I'm currently working on a program that allows for connections to multiple provider specific databases, so obviously I'm using the non-provider-specific classes (in System. Common) to work with these various connections once the connection or data adapter has been instantiated through the use of the provider's implementation.

However, I wanted to make use of the Row Updated and Row Updating events that are supposedly a part of the Data Adapter base class according to MSDN (
