Default values of Class properties - vb.net

Question

I have a class, it looks like this:
Public Class DataPoint
Private _data As Integer
Private _locInText As Integer
Private _searchValue As String
Property Data As Integer
Get
Return _data
End Get
Set(value As Integer)
_data = value
End Set
End Property
Property LocInText As Integer
Get
Return _locInText
End Get
Set(value As Integer)
_locInText = value
End Set
End Property
Property SearchValue As String
Get
Return _searchValue
End Get
Set(value As String)
_searchValue = value
End Set
End Property
End Class
I then create another class using this class.
Public Class PaintData
Public Time As TimeSpan
Public Color As DataPoint
Public Job As New DataPoint
Public MaxCurrent As New DataPoint
End Class
I want to create default values of some of the properties, namly SearchValue and LocInText. To me, it makes sense to do this inside the class definition, because these are essentially constants.
Q1. Should I be doing it this way? If not, what is the proper technique.
Q2. I can't get the syntax right. Can you help?
Public Class PaintData
Public Time As TimeSpan
Public Color As DataPoint
Public Job As New DataPoint
Public MaxCurrent As New DataPoint
Color.LocInText = 4 '<----Declaration expected failure because I'm not in a method
Job.LocInText = 5 '<----Declaration expected failure because I'm not in a method
End Class
Thanks all

Answer 1

Give DataPoint a constructor:
Public Class DataPoint
Private _data As Integer
Private _locInText As Integer
Private _searchValue As String
Public Sub New(locInText as Integer)
_locInText = locInText
End Sub
'...
End Class
And use that:
Public Class PaintData
Public Time As TimeSpan
Public Color As New DataPoint(4)
Public Job As New DataPoint(5)
Public MaxCurrent As New DataPoint(6)
End Class
Alternatively you could use
Public Property Color As DataPoint = New DataPoint With {.LocInText = 4}
in your class definition. This syntax is arguably more readable than the constructor syntax.
