How to Insert one to many relationship using checkboxlist in VB.NET, LINQ to SQL?

Question

I have 3 tables:

CustomerType
CusID

EventType
EventTypeID

CustomerEventType
CusID
EventTypeID

How to Insert one to many relationship using checkboxlist in VB.NET, LINQ to SQL?

dim newEventType = new EventType
newEventType.EventID = 1
db.EventType.InsertOnSubmit(newEventType)
db.submitchange()

Then I want it to automatically insert data into CustomerEventType table based on the last EvenTypeID data that's just inserted and the checks of the CusID that is using CheckBoxList1 bounded from CustomerType (Suppose there are 2 IDs. )

After I Click on Insert button the data in EventType table and CustomerEventType table should be:

EventType
EventTypeID
1

CustomerEventType
EventTypeID.....CusID
1........................1
1........................2


The only question that I have is, what should be the code behind the insert button using VB.NET LINQ-to-SQL to get this result? Please help me out of this problem. Thanks you so much for your time and everything.
May God bless you all.

One way would be to create a custom class CustomerEventType containing EventTypeID and CusID. Then create a collection of CustomerEventType and pass that to a sub routine or function that will loop through and insert each CustomerEventType using linq.
