How can we disable session in Page Level?

In ASP.NET, you can disable session state at the page level by using the 'EnableSessionState' attribute on individual pages or by overriding the 'EnableSessionState' property in a code-behind file.

Here are two approaches to disable session state at the page level:

1. Using the 'EnableSessionState' attribute:
   In the @Page directive of your ASP.NET page, you can add the 'EnableSessionState' attribute and set its value to "False" to disable session state for that particular page.

   
   
   <%@ Page EnableSessionState="False" %>
   
   

   By setting EnableSessionState="False", you are disabling session state for that specific page. This means that the 'Session' object will not be available on that page, and you won't be able to access or modify session state data.
2. Overriding the 'EnableSessionState' property in code-behind:
   In the code-behind file (e.g., 'PageName.aspx.cs'), you can override the 'EnableSessionState' property of the 'Page' class and set it to 'ReadOnly' or 'Disabled' to disable session state.

   
   
       public partial class PageName : System.Web.UI.Page
       {
           protected override System.Web.UI.PageStatePersister PageStatePersister
           {
               get
               {
                   return new SessionPageStatePersister(this);
               }
           }
   
           protected override bool EnableSessionState
           {
               get { return false; }
           }
       }
   
   

   By overriding the 'EnableSessionState' property and setting it to false, you disable session state for the specific page. The 'Session' object won't be available within this page, and session state data cannot be accessed or modified.

Using either of these approaches, you can selectively disable session state for individual pages in your ASP.NET application. This can be useful when you have certain pages that don't require session state or to optimize performance by avoiding unnecessary session-related operations.
