Question

I have problem with !IspostBack
i’m working with crystal report and i use (if not ispostback) to set X and in else to retrieve X
the problem is its working properly in some pages and not working in others.
this code sample.

If Not Page.IsPostBack Then
     Session("VehicleStatusSelectionFormula") = SelectionFormula
Else
     SelectionFormula = Session("VehicleStatusSelectionFormula")
End If

note: is (“EnableViewStateMac=”false”) make if not ispostback doesn’t work ?
beacause the page that doesn’t work has this in page register

<%@ Page Language="vb" AutoEventWireup="false" CodeFile="ReportsVehicleStatusScript.aspx.vb" Inherits="ReportsVehicleStatusScript" **EnableViewStateMac="false"**  %>

please i need some help why its working in some pages and not in others ?

thanks.
