I got this code in my Master page :
<script type="text/javascript">
$("#<%=hfJavaScriptDetected.ClientID %>").val('yes');
</script>
<asp:HiddenField ID="hfJavaScriptDetected" runat="server" Value="no" />
So if Javascript is enabled the value of my hidden field should have be changed.
Now, what I would like to do is check this value on server side and if it's set to "no", I want to redirect the user to the page Javascript.Aspx.
I don't know in which event to look the hidden field value. I try on the Page_Load event but it's seems the hidden field value was not already set.
