Problem of deploying webapp on IIS production server

Hi,

I built and packaged some web applications written by .net and c#. They connect to the same DB and have listview to list data from DB.

They did not have any errors when I built and test them on local development machine.

However, the listview shows the following error when I installed and run them on production server (I can login to the DB and web application, just the ListView does not work):

Info Handling Error System.NullReferenceException: Object reference not set to an instance of an object. at WebControl.ListView.ResponseBuilder.GetIDString(Fields flds) at WebControl.ListView.ResponseBuilder.AddRecord(Fields flds) at WebControl.ListView.DataProcessor.Page_Load(Object sender, EventArgs e)

Then, I uploaded the source of the web applications and test them again. It shows different error message:

"Internal server error 500" when I load the data for listview.

That IIS on production server only allows ONE web application to run ListView. How can I fix it?

Thanks for any kind help
 
It's probably a bug in your code, so without a sample of the code, there's
no real way to tell. The code where the actual exception is being thrown and
maybe some of the preceeding code, would be helpful.

You can also turn on tracing in the config file so that you can actually see
what's going on internally.
