.NullReferenceException: Object reference not set to an instance of an object.

Such issue is usually caused by missing dll in your project folder. If you are using basic feature WebGrid control the required dll in the project folder are:

- ISNet.dll
- ISNet.WebUI.dll
- ISNet.WebUI.WebGrid.dll
- ISNet.WebUI.WebGrid.Resources.dll (if using SmartWebResources)
- ISNet.WebUI.WebDesktop.Resources.dll (if using SmartWebResources)
- ISNet.WebUI.Resources.dll (if using SmartWebResources)

More detailed is available in the WebGrid documentation on the article "Deploying project that uses SmartWebResources" or "Deploying project that does not use SmartWebResources"

Hi,

I am hoping someone can help shed some light on this! We have a large web application which many customers are using without a problem. One customer is trying to move from one server to another. The software works great on the current server.

On the new server, they are getting a problem with lists (IS Net Grids). Here is the stack trace. I don't know what this means so I am a bit stuck. It seems to be something to do with the IS net controls although it must be something at the server level.

Can anyone point me in the right direction?
