Can anyone please help me.
I am new to asp.net. I have been trying for 3 days now to do what i thought is the simplest thing. I am trying to simply create a web page with a datagrid displaying information from one of my sql server tables. this is the first asp.net project i am doing. I followed a walkthrough and i keep getting this error:

Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection

Please can anyone lead me in some direction...
any help would be greatly appreciated.
Thanks.
