GridView not updating or deleting

[TheDebbis]

I'm making a quick CD catalog to help me learn ASP.NET (using C# primarily.) I have a number of gridview's on my site that are working properly, but for some reason, one is not updating or deleting. I have the buttons for both visible, and when I click edit, the update fields show up properly, but once I click 'update' the table is back with it's old information. When I click 'delete' the page completes the postback properly, but once again, the information is the same.

Here is my source code for the page in question:

<asp:GridView ID="FullEditAlbumGridView" runat="server" AllowPaging="True" AllowSorting="True"
        AutoGenerateColumns="False" DataSourceID="FullEditSqlDataSource" Width="717px" AutoGenerateDeleteButton="True" AutoGenerateEditButton="True">
