Inherits UserControl
Private uds As DataSet

Public Property uDataSource() As DataSet

Return uds
End Get
Set(ByVal value As DataSet)
uds = value
End Set
End Property

End Class

When you set the value of your uDataSource be sure to set it to a Dataset in your project (not a BindingSource component)

If you drill into the 'Other Data SOurces' node you need to pick the instance of the DataSet on your form - this should not error!

hope that helps,
