Adding DataRow to view state...little problem.

I have a stongly typed Dataset. From this a get a new strongly typed datarow.
I want to add this to my viewstate.

But I get the following error:

Woof

Odd... the datarow class is marked serializable.

What I think, is that the datarow either contains a nonserializable member, or contains a reference to something we haven't considered yet.

I think you should add the entire datatable/dataset to viewstate.

VB Code:

<Serializable(),  _
 System.ComponentModel.DesignerCategoryAttribute("code"),  _
 System.Diagnostics.DebuggerStepThrough(),  _
 System.ComponentModel.ToolboxItem(true)>  _
Public Class dsBooking
    Inherits DataSet
    
    Private tableBookingDetail As BookingDetailDataTable
    
    Public Sub New()
        MyBase.New
        Me.InitClass
        Dim schemaChangedHandler As System.ComponentModel.CollectionChangeEventHandler = AddressOf Me.SchemaChanged
        AddHandler Me.Tables.CollectionChanged, schemaChangedHandler
        AddHandler Me.Relations.CollectionChanged, schemaChangedHandler
    End Sub
 
   'Blah blah blah
 
   <System.Diagnostics.DebuggerStepThrough()>  _
    Public Class BookingDetailRow
        Inherits DataRow
        
        Private tableBookingDetail As BookingDetailDataTable
        
        Friend Sub New(ByVal rb As DataRowBuilder)
            MyBase.New(rb)
            Me.tableBookingDetail = CType(Me.Table,BookingDetailDataTable)
        End Sub
 
        'blah blah blah
 
    End Class
 
End Class

This strongly typed DataRow is declared, Public Class bit, inside the strongly typed dataset.
As you can see the DataSet is Serializable, but the DataRow doesn't have this.

I cannot stopre the entire dataset as a function I have only returns a strongly typed datarow:

VB Code:

Public Function FetchBookingToEdit(ByVal BookingKey As Integer) As Booking.BookingDetailRow
        Dim SQL As String = EditSQL
 
        SQL &= "WHERE BookingKey = @BookingKey "
 
        Dim Comm As New Mowlem.Data.DataLib.Command(SQL)
 
        Comm.Parameters.Add("@BookingKey", BookingKey)
 
        Dim dt As New Booking
 
        MyBase.DataLib.FillDataTable(Comm, dt.BookingDetail)
 
        If dt.BookingDetail.Rows.Count = 1 Then
            Return dt.BookingDetail.Item(0)
        End If
    End Function

Where the booking class, Dim dt As New Booking, inherits my strongly typed dataset.

Woof

Did you try making it serializable? Or add it to the session object(?)

Still doesn't work if I make it serializable :(
Session state...hmmmm...can't tell when a user closes down the popup window and therefore the objct will stay in the session collection. gonna reload the object of Page_load me thinks.

Booooo

woof

Just a hunch, but when you're making it serializable, mark all your methods and properties as nonserializable.

Does it work after that?
