window.history.forward(1) + Master Page+Panel + Update Panel

Apr 1 2018 9:40 AM

Hi Team,

I have a master Page solution with update panel in WebForm2.aspx which has 2 panel controls. On Page Load I am hiding Panel2 and on click of button in Panel1 I am showing the Panel2. Both these panels are enclosed between Update Panel.

With out update panel on the Web Form2.aspx right clicking the page and clicking back does not load the page from cache. But, with update panel control it displays me the First panel which I need to restrict it. Any help appreciated. Thanks

Code

Site1.Master

<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Site1.master.cs" Inherits="WebApplication2.Site1" %>
