Webgrid databinding causing blank screen

Hey,

I have a page where there is only 1 webgrid. When the page loads I get a blank white screen. This only happens sometimes, but when it happens the logs show the following exception:

DATETIME: (hidden)

USERNAME: (hidden)

CLIENTID: (hidden)

TARGETNAME: APPLICATION_ERROR: ProcessRequest

METHODNAME: Application_Error

MESSAGE: Exception of type 'System.Web.HttpUnhandledException' was thrown.Object reference not set to an instance of an object.

INNER STACKTRACE:

I checked the data to make sure there might be something there but that looks fine. The weird thing is I only get this error sometimes. Any help would be greatly appreciated. Thanks.
