Unhappy Gridview Chapter 17 error

Hi all,

Hopefully someone can help. Just started Visual Basic - using Visual Studio 2005 pro
and connecting to a sql database on a seperate server

Entered the code from the Try it Out on Page 575 with some amendments as follows to connect to the sql database.

<%@PageLanguage="VB"AutoEventWireup="false"CodeFile="Default.aspx.vb"Inherits="_Default" %>
<!DOCTYPEhtmlPUBLIC"-//W3C//DTD XHTML 1.0 Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<title>Grid View</title>
connectionstring="Server=*********; User ID=AME;
password=********* ;database=AME;"
SelectCommand="SELECT txtAnimal, txtColour FROM tblAnimalTypes"
UpdateCommand="UPDATE tblAnimaltypes SET txtColour = @txtColour where txtAnimal = @original_txtAnimal">

Without the <asp:CommandField line the data grid is shown with data from the database but with any editing facilities

With the <asp:CommandField line the following error is given

Error 1 System.Web.UI.WebControls.DataGridColumnCollection must have items of type 'System.Web.UI.WebControls.DataGridColumn'. 'asp:CommandField' is of type 'System.Web.UI.WebControls.CommandField'. C:\WebSite\DataGridView\Default.aspx 31

The default.aspx.vb has the following

PartialClass _Default
Inherits System.Web.UI.Page

Any help would be appreciated
