NullReferenceException Problem

Last Modified: 2016-02-19
I am retrieving some data form a table using linq.  I am pulling that info into text boxes I have on a form.  But because some of the fields may be null and there is no way to know which ones will be null at any given time, thus I keep getting a NullReferenceException or an Object reference not set to an instance of an object error.  I have tried everything to try to test the field to see if it is null but nothing has work.
