Session and Remove
I wish to remove all item in my session, how do I do that? I have tried to use the code below, but this generates an error. It's the code in the Sub Fjern(..)
Code:
sub page_load()
if not page.IsPostback then
Session("BasketCount") = New ArrayList()
Dim vareArray(5) as string
Dim strVare as String
vareArray(0) = "Kartofler"
vareArray(1) = "Gulerødder"
vareArray(2) = "Æbler"
vareArray(3) = "Appelsiner"
vareArray(4) = "Pærer"
vareArray(5) = "Agurker"
for each strVare in vareArray
drpList.items.add(strVare)
next
end if
end sub
public Sub Fjern(sender As Object, e As EventArgs)
dim i as integer
dim j as integer
j = session("basketCount").count - 1
i = 1
For i=1 to j
Session("BasketCount").RemoveAt(i)
i = i + 1
Next
vareListe.text = ""
End Sub

Hi, it doesn't seems like ArrayList support the abandon method, as you can see from the error message in this code.
Code:
<%@ Page Language="VB" %>
<script runat="server">
sub page_load()
if not page.IsPostback then
Session("BasketCount") = New ArrayList()
Dim vareArray(5) as string
Dim strVare as String
vareArray(0) = "Kartofler"
vareArray(1) = "Gulerødder"
vareArray(2) = "Æbler"
vareArray(3) = "Appelsiner"
vareArray(4) = "Pærer"
vareArray(5) = "Agurker"
for each strVare in vareArray
drpList.items.add(strVare)
next
end if
end sub
public Sub Fjern(sender As Object, e As EventArgs)
Session("BasketCount").Abandon()
vareListe.text = ""
End Sub
Sub Tilfoej(Sender As Object, E As Eventargs)
'Her sættes værdierne i ArrayList
Dim strTekst as String
Dim Item as String
'Her tilføjes en bog til listen, hvis der er skrevet noget i tekstboksen
Session("BasketCount").Add(drpList.selectedItem.text)
dim i as integer
i = 1
For Each Item in Session("BasketCount")
StrTekst = StrTekst & "<br />" & i & " " & Item
i = i + 1
Next
vareListe.Text = "Antal varer: " & Session("BasketCount").Count & "<br />Varer: " & StrTekst
End Sub
