DataSource Controls :: Linq DataContextObject To TextBox And Label?

I pretty new to Linq and I am attempting to solve this problem.I have a stored procedure (that I am accessing via LINQ datacontextobject) that accepts a UserID parameter during the pageload event in the codebehind.I am able to bind the single row that is returned to a gridview.I cannot seem bind the individual columns to labels or textboxes.I want to do this purely in the codebehind and not using a data source control.here is the code i have thus far in the Page_Load event:

Dim userinfo As New BizMarketDataContext
Dim invInfo = userinfo.SelectUserInfo(Membership.GetUser.ProviderUserKey)
GridView1.DataSource = invInfo
GridView1.DataBind()

The underlying database table has several columns (First Name, Last Name, etc) that I would like to assign to individual textboxes.
