  Hi shsu,

  Do you want to disable the goback button on the page? If so, you can try below code.

  The preventBack() method disable the goback button.

  <script type="text/javascript">
          function preventBack() { window.history.forward(); }
          setTimeout("preventBack()", 0);
          window.onunload = function () { null };
      </script>
  
  <form id="form1" runat="server">
          <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
      </form>
  
  protected void Button1_Click(object sender, EventArgs e)
          {
              Response.Write("This is the refreshed page");
          }

  The result:

  There are 4 solutions describe here

  https://lennilobel.wordpress.com/2009/07/26/defeat-the-evil-back-button-in-your-asp-net-applications/

  For Server Side:

  protected override void OnPreInit(EventArgs e)
  {
      base.OnPreInit(e);
   
      Response.Buffer = true;
      Response.ExpiresAbsolute = DateTime.Now.AddDays(-1d);
      Response.Expires = -1500;
      Response.CacheControl = "no-cache";
      Response.Cache.SetCacheability(HttpCacheability.NoCache);
  }

  We cannot solve our problems with the same thinking we used when we created them.
