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 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?

Example, you have report.rpt means.. open report.rpt then right click Insert->section->select report header from left side option then in right side un-check the Suppress (No Drill Down)->ok
Now you can see your report header section..

 Sounds like you need to read up on master-details type of stuff.

Exactly, you can't magically claim it's a Word file, if it isn't. You can send a text file, or you an interop Word to create a Word file to send.
