Urgent Help Needed on Session.get_Item evaluated

Dear all,

I having a problem here. The situation is as follow, I have a web system with is using C#, if error occur it will capture the error in Global.asax.cs in "Application_Error" and it will kept the error message in a session - Session["ErrorMsg"].

In Global.asax.cs it wil redirect to an error page - "ErrorPage.aspx" to display the error message reading from the session.

The problem is on "Page_Load" in "ErrorPage.aspx", it try to read the Session["ErrorMsg"] but it return error which is :- "function 'Session.get_Item' evaluated and returned null"

What is the problem that cause the error ? Would help if example is provided.

Thanks in advance.

There could be a lot of causes for this.

The simplest solution to try first:

Immediately after setting the Session["ErrorMsg"] object, you should call Server.ClearError() in order to preserve Session state.

eg.

Session["ErrorMsg"] = Server.GetLastError.InnerException;
Server.ClearError();

Try that first, we can go from there.
