DataList Problems

[Guest]

I'm trying to build a commerce site and i can't understand why my DataList controls acts diferent with the same code in the same page
My database contains amoung others 'category', 'subcategory' and 'product'
I have a DataList for each column in the database. when i select a category from the cathegory DataList - the Subcategory DataList loads, and when i click on a subcategory the Product DataList loads, and in the end when i choose a product the details are shown. But it doesen't work. It only works the first time the page loads when i click on a product from the DataList the details are shown (first time are shown 'Special Offers' in the Product DataList)

i don't know what to do. The code is the same for every DataList so why they are not working the same

url to this page is
http://www.sharpdev.r
url to default page source code is
http://www.sharpdev.ro/source.ra

When i click on a datalist a session variable is chainging to let the other DataLists what to Display on PostBack

<%@ Page language="c#" Codebehind="Default.aspx.cs" AutoEventWireup="false" Inherits="sdsite.Default" smartNavigation="true" EnableSessionState="True" enableViewState="False"%><%@ OutputCache duration="200" location ="Any" VaryByParam = "*" %

Could it be becouse of Session State? I used this on a site without session state and it worked well. (http://imobiliare.sharpdev.ro

And another problem is that the Session ID does not always apear in the browser's address bar

thank you

it may be because of session state. the variables in the session state are not keeped in memory. Is there any settings i shoud know?
