See the requirement.
If you want to clear a particular Session data
Then do as follows
Session["UserData"]=null;
And If you want clear Session data from whole of the application the do as above
Session.Abandon();

The question wasn't about how to clear from session, but about the choosing the right ASP.NET event where the session data to be cleared.

So Then you have to follow up
Global.asax file with the Session_OnStart and Session_OnEnd events defined.
See for more details

For a particular session null no need to mention page_load event. It can be done as well as at any event of a page.

Solution 1

You can Use Session.Clear(); or Session.Abandon();

Solution 5

In this case you have to save last visited page url on the session.

HttpApplication.BeginRequest Event fires whenever user request page. Even this is the first event which fires once user request the page.

Inside this event you can check if the last page is your page and current page is not equal to last page, you can clear session.

C#

Session["Session_name"]=null;

Thanks

You should do it in Page_Load event but only only if the page was not post back like in the next example:

C#

protected void Page_Load(object sender, EventArgs e)
{
 if (!Page.IsPostBack)
 {
    //clear your params from sesssion here!
    Session["param1"]= null;
    Session["param2"]= null;
    //...

 }
 //.... 
}
