.NET Forum / ASP.NET / General / September 2007The IListSource does not contain any data sources.
Hello: I have migrated a site from IIS5 to IIS6. The site is configured and the we app is installed on the new IIS site. I can get to the web page but when I try to login, this is what I get the following error below. I would appreciate any insight, direction or help regarding this. Thank-you!!

I am very new to .NET and programming, very new :-) How can I trace my code? What more information can I provide to get some more help? Your assistance is much appreciated.

Read about debugging and how to set a breakpoint if you don't know how. use F11 to step through the code line by line, to narrow down where the error is occurring. use F10 to step over etc... I am assuming you are getting some data from a database to authenticate the user etc.. check if you are getting any data back if you expecting data back. You said that things break after you try to login, are you being authenticated? Without seeing any code it is very difficult to help you out.

Ozi, Yes, the application is accessing a SQL database which I believe is defined within the code (I believe it is defiend in the web config file). I don't know what you mean the code behind this page. I thought what I sent you is the code. How can I find where the code behind this page is?
