Checking that cookies are enabled in ASP.NET

Create a file called CheckCookie.ascx on your site. Copy and paste this text into the file:

<%@ Control Language="vb" AutoEventWireup="false" %>
<script runat="server">
    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs)
        If (Me.IsPostBack) Then
            If Me.Request.Cookies.Item(Me.UniqueID) Is Nothing Then
                If Not Me.FindControl("message") Is Nothing Then
                    Me.FindControl("message").Visible = True
                End If
            End If
        Else
            Response.Cookies.Add(New HttpCookie(Me.UniqueID))
        End If
    End Sub
</script>
<div id="message" runat="server" visible="false">
  You do not have cookies enabled.
</div>

This is called an ASP.NET user control. It is sort of like an HTML include file + script. Each time there is a postback (clicking Add to Cart for example) it will check for a cookie. If this cookie does not exist it will display the message.

Now add this user control to the pages where you want the message to appear when they do not have cookies enabled. To add the control, add this line to the top of the file:

<%@ Register TagPrefix="ss" TagName="CheckCookie" Src="CheckCookie.ascx" %>

<ss:CheckCookie id="cc" runat="server" />
