DataList.DeleteCommand event is not getting fired

I have a DataList that has an Button as one of the controls in it's
ItemTemplate. The Button has a CommandName="delete" attribute, but when I
click it the DeleteCommand event doesn't even get fired. I have checked
everything I could think of, but everything looks correct to me. Here is the
relevant code from the *.aspx file and the *.aspx.vb files (if I missed
something that is relevant, let me know):


ASPX File:

<asp:datalist id="datImages" runat="server" EnableViewState="False"
CellPadding="0" CellSpacing="5" RepeatColumns="3"
RepeatDirection="Horizontal" DataKeyField="contentid">
<ItemStyle HorizontalAlign="Center" VerticalAlign="Bottom"></ItemStyle>
<ItemTemplate>
<uc1:captionimage id="CapImg" runat="server" EnableViewState="False"
photo='<%#
DataBinder.Eval(Container,"DataItem.content","newsinfo/{0}").Trim() %>'
caption='<%# DataBinder.Eval(Container, "DataItem.textcaption").Trim()
%>'></uc1:captionimage><BR><BR>
<asp:Button id="btnDeleteImg" runat="server" CausesValidation="False"
Font-Bold="True" EnableViewState="False" Text="Delete"
CommandName="delete"></asp:Button>
</ItemTemplate>
</asp:datalist>



ASPX.VB File:

Private Sub datImages_DeleteCommand(ByVal source As Object, ByVal e As
System.Web.UI.WebControls.DataListCommandEventArgs) Handles
datImages.DeleteCommand
Dim cmdDelete As New OleDbCommand("DELETE FROM newsinfo WHERE contentid=" &
CInt(datLinksFiles.DataKeys(e.Item.ItemIndex)), New
OleDbConnection(Global.connectionstring))

cmdDelete.Connection.Open()
cmdDelete.ExecuteNonQuery()
cmdDelete.Connection.Close()
If System.IO.File.Exists(Server.MapPath("newsinfo/" &
CStr(CType(e.Item.DataItem, DataRowView).Row("content")))) Then
System.IO.File.Delete(Server.MapPath("newsinfo/" &
CStr(CType(e.Item.DataItem, DataRowView).Row("content"))))
Me.RefreshResults()
End Sub


Does anybody have any idea what could be causing the datImages.DeleteCommand
event not to be raised? Thank you.
