I am trying to use the delete function of the Gridview control. I drag the
db table to the ide, add the delete command and parameter. I always get and
exception that the stored procedure expects a parameter that was not passed.
The code follows and you can see the parameter is there. This has been the
same for beta1 and beta 2. It must be me. What am I doing wrong?

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="SqlDataSource1"

EmptyDataText="There are no data records to display." AllowSorting="True">

<Columns>

<asp:CommandField ShowDeleteButton="True" />
