Solution 1

First put sessionvalue in page

Session["_eventId"]=12;

They key part of this answer is that the handler must be modified to inherit from IRequiresSessionState in order to have access to the Session

public class Upload : IHttpHandler, System.Web.SessionState.IRequiresSessionState
{
...

 if(  context.Session["_eventId"] !=null))
  evtObj.eventId =  int.Parse(context.Session["_eventId"].ToString())

....

Solution 2

When you want to get access to your Session state from an ASHX or HttpHandler, you have to implement IReadOnlySessionState:

C#

public class Upload : IHttpHandler, IReadOnlySessionState
{
   public bool IsReusable { get { return true; } } 
   
  //Add you code from here
  //...
}
