datarows and session state

[Guest]

hey all,

i have 2 scenarios to run by you.
public class test
dim _entireRow as dataRow
public property mEntireRow as DataRow
'get and set _entireRow
public property mOneField as String
'get and set _entireRow.Field
end class

it seems to me in testing that if i save an object in session state that
contain these properties the mEntireRow returns Nothing however mOneField is
saved. This doesn't make any sense to because both properties are based on
the same member row.

thanks,
rodchar

From the code outline you posted, i don't see how your test case could show
that the datarow would be null. Why don't you post a sample piece of code to
demonstrate the issue. For a short but complete program, look here

when i save the following object in session and on postback bring it back
mRow is Nothing and mFirstName and mLastName have values.


Public Class Employee
Dim oDt As DsNorthwind.EmployeesDataTable
Dim oEmployeeDataHelper As EmployeeDataHelper
Dim _dr As DsNorthwind.EmployeesRow
Public Sub New(ByVal dt As DsNorthwind.EmployeesDataTable)
oDt = dt
oEmployeeDataHelper = New EmployeeDataHelper
End Sub

Public Property mFirstName() As String
Get
Return _dr.FirstName
End Get
Set(ByVal value As String)
_dr.FirstName = value
End Set
End Property
Public Property mLastName() As String
Get
Return _dr.LastName
End Get
Set(ByVal value As String)
_dr.LastName = value
End Set
End Property

Public Property mRow() As DsNorthwind.EmployeesRow
Get
Return _dr
End Get
Set(ByVal Value As DsNorthwind.EmployeesRow)
_dr = Value
End Set
End Property
Public Sub RetrieveAllEmployees()
oEmployeeDataHelper.RetrieveAllEmployees(oDt)
End Sub

Public Sub RetrieveEmployee(ByVal id As Integer)
_dr = oDt.NewEmployeesRow
oEmployeeDataHelper.RetrieveSingleEmployee(id, _dr)
End Sub
End Class
