Binding + Database Linking - 500 pts

I have asked a similar question to this before, however this time I will provide the full scenario.

I have a contact table which has all the usual fields plus PhoneNumber and PhoneDescription 1 -5

These fields are bound to a form, the reason for keeping them all within the same table was to provide easier binding. It allows the user to change each phone description and number very easily. I choose five as this will be the maximum it will ever be.


The problem I have is that I am still wondering whether the contacts phone numbers should go in another table, the problem is that while it is the correct way to link it, it causes significant coding to get it working.

Ideas anyone

I hope you are working with datatables.

Say DataTable1 have your usual fields with a PKey
Make another table DataTable2 with PKey, ContactPhone and ContactDescription.
Create a DataSet (Dim ds as New System.Data.Dataset)
ds.Add(DataTable1)
ds.Add(DataTable2)
'\\ Relate Parent Table(usual fields) with Phone Table as shown below
ds.relations.Add("RelationName",ds.Tables(0).Columns("PKey"),ds.Tables(1).Columns("PKey"))

and for data binding, use ds.Tables(0).DefaultView.
Hope this will help you.
Cheers!!!

No I am not, the form is bound to the object.
