Manually deleting from grid without sqldatasource

[Simon]

I have a grid

<telerik:RadGrid ID="RadGridFeedings" runat="server" AllowAutomaticInserts="True" AllowAutomaticUpdates="True"  AllowAutomaticDeletes="True" AutoGenerateColumns="false" AllowPaging="True" AllowSorting="True" PageSize="10" skin="Default">
                            <PagerStyle Mode="NumericPages" />
                            <GroupingSettings CaseSensitive="false" />
                            <MasterTableView TableLayout="Fixed" Width="100%" CommandItemDisplay="top" DataKeyNames="FeedID" AutoGenerateColumns="false">
                                <Columns>
                                    <telerik:GridDateTimeColumn HeaderText="Date" DataField="FeedDate" UniqueName="FeedDate"
                                        SortExpression="FeedDate" HeaderStyle-Width="20%" ShowFilterIcon="false" DataFormatString="{0:dd/MM/yyyy}" />
                                    <telerik:GridBoundColumn HeaderText="Type" DataField="FoodType" UniqueName="FoodType"
                                        SortExpression="FoodType" HeaderStyle-Width="23%" ShowFilterIcon="false" />
                                    <telerik:GridBoundColumn HeaderText="Size" DataField="FoodSize" UniqueName="FoodSize"
                                        SortExpression="FoodSize" HeaderStyle-Width="22%" ShowFilterIcon="false" />
                                    <telerik:GridBoundColumn HeaderText="Result" DataField="Result" UniqueName="Result"
                                        SortExpression="Result" HeaderStyle-Width="22%" ShowFilterIcon="false" />
                                    <telerik:GridButtonColumn ConfirmText="Delete this product?" ConfirmDialogType="RadWindow"
                    ConfirmTitle="Delete" ButtonType="ImageButton" CommandName="Delete" Text="Delete"
                    UniqueName="DeleteColumn">
                    <ItemStyle HorizontalAlign="Center"/>
                </telerik:GridButtonColumn>
                                </Columns>                                
                            </MasterTableView>
                        </telerik:RadGrid>

that is being loaded using a datatable via the code behind

Dim dtFeedings As DataTable = RVSelect.SelectFeedings(-1, -1, Request.QueryString("AnimalID"), "", -1, -1, "").Tables(0)
RadGridFeedings.DataSource = dtFeedings
RadGridFeedings.DataBind()

How do I get the edit/delete buttons working in this scenario as all the examples use sqldatasources or linqdatasources?

Many thanks
Simon
