So, you call GetHomeSlides, which builds and returns an ArrayList of URLs, but then you don't do anything with them. You effectively throw away the results. Perhaps you should assign the result of the method to something.
Oh... and this code:

Nice... What exactly does that do? (Yes, I know the answer, I want you to think about it)

Hi,
Bind all your data to a DataList control. And keep an identification on a HiddenField to identify the row of the above condition is true.
<asp:DataList ID="DataList1" runat="server" OnItemDataBound="DataList1_ItemDataBound">
<ItemTemplate>
<asp:HiddenField ID="HiddenField1" runat="server" />
<asp:Label ID="Label1" runat="server" Text='<%#Eval("Title") %>'></asp:Label>
<cc1:CollapsiblePanelExtender ID="CollapsiblePanelExtender1" runat="server" ExpandControlID="Label1"
CollapseControlID="Label1" TargetControlID="Panel1">
</cc1:CollapsiblePanelExtender>
<asp:Panel ID="Panel1" runat="server">
<asp:Label ID="Label2" runat="server" Text='<%#Eval("Description") %>'></asp:Label>
</asp:Panel>
</ItemTemplate>
</asp:DataList>
On DataList1_ItemDataBound use the FindControl method to locate the HiddenValue and set the required panel collapse and expand as for the requirement. Or with out binding the details you could bind it at the time of selection of the title and expand it.
Hope it helps
Thx,
Gayani

Hi all,
Im using VS 2003 for my small application, and there im using repeater control, there i need check each row in repeater control is there any web url is in data content, and if there any web url i need to set different color for that particular row, im bit stuck of that, pls help me to do this
Thank you.

You can iterate rows in the repeater control. Regular expression can be used to check whether the data has a URL. Check this[^] which has regular expression examples (not checked whether it has a regex for URL). Changing the color will be trivial.

Okay, it says you don't have much idea about what session and cache is. BTW, keeping shopping cart items in session is not a good idea. I'd create a table something named "shopping" in the database and keep the items there which can be accessed using the session id.
Keeping items to session is trivial. Say you have a product class named "Product". Then you can keep a generic List<Product> instance in the session which represents shopping cart items. To add items,
List<Product> shoppingCart = Session["ShoppingCart"] as List<Product> ;
shoppingCart.Add(new Product());

 If you don't want to move to shopping cart page, just don't redirect after adding item.

I have a website using forms authentication. I seem to have a problem with it and I'd appreciate if you could help me on this. I use <forms timeout="600"> and <sessionState timeout="600"> in web.config. In login page I have this code:
protected void pageLogin_Authenticate(object sender, AuthenticateEventArgs e)
{
if (Membership.ValidateUser(this.pageLogin.UserName.Trim(),this.pageLogin.Password.Trim()))
{
MembershipUser u = Membership.GetUser(this.pageLogin.UserName.Trim(), false);
Session["UserId"] = u.ProviderUserKey.ToString();
e.Authenticated = true;
}
else
{
e.Authenticated = false;
}
}
protected void pageLogin_LoggedIn(object sender, EventArgs e)
{
FormsAuthentication.RedirectFromLoginPage(Session["UserId"].ToString(), false);
}
I use Session["UserId"] on other protected pages. The problem is, sometimes when I refresh a page after a short while that uses Session["UserId"] I get null reference error on Session["UserId"] line. Why it is expiring so soon, I don't have anything modifying web.config or the website so I don't think IIS is recycling. And shouldn't it redirect to login page if session is expired? Am I missing something here?
This is on WinXp sp2 and IIS6.

what authentication mode did you set in IIS ? if you have used forms then you should select Anonumous authentication.

currently i m using asp.net with c# (.net 2005, 2.0 framework) and SQL SERVER database.
Here i launched my project in server and data will be fetched and processed by users.
Here i want to protect records and it should not fetched by more than one person.
For example..
if the record "1" has been taken by a user, then it should be locked and no other user should fetch it (a message should be prompt).After the completion of work and if the user release it (finished processed and save/cancel) then it can be accessed by others..
how to implement it...
help me. thanks in advace - KARAN

Hi,
I created a web application in ASP.NET 2.0 with just a label and a button. In the button click i've the code:
Label1.Text = Server.MapPath("/mapTest");
I deployed this app in a Windows 2000 Server SP4, and in my Win Xp Pro SP3. The app was deployed in D:\TestFolder\
The Label text in Win XP was:
D:\TestFolder\default.aspx
The Label text in Win 2000 SP4 Server was:
C:\Inetpub\wwwroot\TestFolder\default.aspx
Could anyone please explain why this happens?
Regards,
Blumen

In Win 2000, Virtual Directy - > Right Click on your virtual Directory - > Propertires - > Check Local path in Virtual Directory TAB.
what is that ?

In Windows XP pro the site has to be a virtual directory (as the IIS is limited to the default site), but in Windows 2000 server it could be a web site.
Have you deployed it as a site or a virtual directory on Windows 2000 server?
Despite everything, the person most likely to be fooling you next is yourself.

Thank you for the reply.

I din't understand the above part.
In Windows 2000, I've deployed it as a virtual directory. What would be the difference in deploying as a website?
