Weird Dotnet Issue

[Hai Nguyen]

Hi all

I encounter a problem but don't know how to solve it.

Here is my situtation:

I have a web page, 2 user controls: A and B. A and B are dynamically loaded
into the main page. In B there are 4 buttons, TextBox, object and
classes,...There is one object I want to save all of its values and I
decided to use
Session["utility"] = myobject. For the first 3 button, I always remember to
assign that object back to the Session for the next use, and it works fine
for the first 3 buttons. The last button is a "Save All" button and I also
want to retrive that object by: myojbect =
(myclasstypehere)Session["utility"]. It breaks my code. Running debug I
receive this: myobjec is null and there is a message like this:"
Session["utility"] function 'Session.get_Item' evaluated and returned null
".

I don't know why it gave me that error. I works with 3 other buttons but not
with this.

Thanks for any help

Apparently, when you are assigning myObject to Session["utility"], it is not
initialized, and is null. Either that, or the Session data is being lost
somehow (not likely).

When I debugged, that object apprantely had a value. I don't know why after
postback it seemed the Session was swept out

Appreciate any suggestions

Thanks
