ASP.net session problem making me go nutz!

programming
1

Hi!

The code below has a simple task. However it does not manage to do the right thing. The whole point is that I want a session variable to save a string after I’ve clicked a button. And then after postback it should retain the value from the session variable and put it in a label control.

It does not work, I have to press the button twice to see the result I want. Is there something wrong with my code?

This is a dummy version of a cart that I am developing, with a generic List<T> which will reside inside a session variable that contains the names of certain controls that will be rendered after postback in the Page_Load event.

I’d gladly accept any help and/or suggestions!
