LinqDataSource wont run updates on all columns of a GridView?

[Andy B]

I have a GridView with a LINQDataSource attached to it. My code in the aspx
markup is below. I need to know why only the checkbox field for the
activated column is getting updated (the EditTemplate). None of the other
columns get updated except for that one. Any ideas? The only column that is
not able to be updated is the ID column, but that isn't even in the table.

<asp:GridView ID="EternityNew sMemberList" runat="server" AllowPaging="Tr ue"
AutoGenerateCol umns="False" DataSourceID="E ternityNewsMemb erListDataSourc e"
EmptyDataText=" There are no members yet." HorizontalAlign ="Center"
ShowFooter="Tru e" DataKeyNames="I D">
