Hello,

I have a method in Page_Load(object sender, EventArgs e) that generates some dynamic html codes.
After navigating the page to another page, When I click the back button of my IE, I wont have my generated html. The problem is Page_Load doesn't run again.

How can I solve this problem.

C#

protected void Page_Load(object sender, EventArgs e)
{
    CreateHTMLControls();
}

As an alternative, add the below code in Page_Load method to retain the content on back operation.

C#

if (this.Master.Page.Header != null && Session["RELOAD"] == null) 
{ 
 System.Web.UI.HtmlControls.HtmlHead hh = this.Master.Page.Header; 
 System.Web.UI.HtmlControls.HtmlMeta hm = new System.Web.UI.HtmlControls.HtmlMeta(); 
 hm.Attributes.Add("http-equiv", "Refresh"); 
 hm.Attributes.Add("content", "3"); 
 hh.Controls.Add(hm); 
}

Thank you. I thought it worked but it was refreshing the page alternately.

Hi,

Place this code in Page_Load event:

C#

Response.CacheControl = "no-cache";
Response.AddHeader("Pragma", "no-cache");
Response.Expires = -1;

The reason for the page executing doesn't affect the page cycle, the Load event always fires when the page is executed.

So, if the Page_Load doesn't run sometimes, it is because the page is cached and doesnt execute on the server. The page can be cached in the browser, in a router somewhere along the way, or on the server using server side page caching

Try disabling output cache and see if the problem still occurs:

XML

<system.web>   
  <caching>     
   <outputCache enableOutputCache="false"/>
  </caching> 
<system.web>
