Session management in user control

I am using below mention code in a web usercontrol for
session management for hastable objects.
Code works sometime and sometime it doesnt work. Is there
some problme in code:

Private Sub SaveState()

Session.Item(Me.ID & "cols") = ColumnsListHashTable
Session.Item(Me.ID & "status") = StatusHashTable
End Sub
Private Sub GetState()
ColumnsListHashTable = Session.Item(Me.ID & "cols")
StatusHashTable = Session.Item(Me.ID & "status")

End Sub

re: Session management in user control

Hi vikram:

By not work, do you mean you get a null reference exception?

re: Session management in user control

I'd put a breakpoint in both methods, or trace statements, andmake
sure SaveState is always called before GetState.
