I want to add a calculated field to my DataSet, similar to how I would add a ReadOnly Property to my class that returned a calculation based on other Properties.

I started off with this in the .vb file of the DataSet:

Partial Class PrescreenDataSet

    Private columnStatus As System.Data.DataColumn

    <System.Diagnostics.DebuggerNonUserCodeAttribute()> _
    Public ReadOnly Property StatusColumn() As System.Data.DataColumn
        Get
            Return columnStatus
        End Get
    End Property

End Class

but I don't know how to return a calculation from other fields. Anybody have a template for this?
