  Hi guys.Newbie here. Im doing my first project with C# and asp.net 3.5 and i cant get past the same error:

  **Server Error in '/' Application

  Compilation Error Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

  Compiler Error Message: CS1061: 'BookPic' does not contain a definition for 'UserName' and no extension method 'UserName' accepting a first argument of type 'BookPic' could be found (are you missing a using directive or an assembly reference?)

  Source Error:

  Line 28: { Line 29: BookPic myBookPic = (BookPic)e.NewObject; Line 30: myBookPic.UserName = User.Identity.Name; Line 31: } Line 32: }

  Source File: c:\Documents and Settings\Administrator\My Documents\Visual Studio 2008\WebSites\SALFORDBOOKSHOP\NewBookPics.aspx.cs Line: 30 **

  Im not sure why it is telling me this as my table BookPic does contain UserName. Im not sure how else to intepretate the error message. Here is my code:

  NewBookPics.aspx:

  <%@ Page Language="C#" MasterPageFile="~/MasterPages/MasterPage.master" AutoEventWireup="true" CodeFile="NewBookPics.aspx.cs" Inherits="NewBookPics" Title="New Book Pics" %>
