event delegate communication question

I've got a webapp that uses an event to respond to changes to a
datahub.  I'd like to display the information that comes in with the
event handler to a textbox.  For the event e, just doing textbox.text
= e.message;  returns nothing.  I've managed to get the data by
putting it an application state variable. Then using the page_load
to put it in the textbox.  (a session state variable didn't work.)
The problem with this is it seems to take some sort of control action
such as clicking on a button or other control to make the update
happen.  I suppose what I need is to be able to simulate a button
click.  Any clues?

Thanks,

Robert Megee

Still unclear about your problem... some sample code of what exactly
this 'e' is, how is it being used, how is the event-handler being
invoked etc is needed.

Let's see what I can provide.
I use Visual Studio Dotnet 2003.  So far every event that has ever
been coded for my web applications use "e" for the event arguments.
So I just thought that it was a standard.  I'll try to be a bit more
specific.
I've got a socket based datahub that I'm subscribing to for events.

I reference a ddl to do the actual communications.   Here's the code:

public class Webpage : System.Web.UI.Page
{
Using Hume.DMH;

protected System.Web.UI.WebControls.TextBox tb1;

tb1.Text = e.message.ToString();

???

e.message is a string so the forced conversion isn't necessary.

EventArgs does not have a Message property.
e.Message should generate a compile time error.

Hmmm, but it does pass a value back if I put into an Application state
variable.
