The RadListView control does not have an item placeholder specified.

[Pierre]

HI, I got this error when I try to disply a image in the listview:

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: The RadListView control does not have an item placeholder specified.

here the listviews

                                <telerik:RadListView runat="server" ID="RadLVPhotos" Enabled="false"
                                    AllowPaging="true" PageSize="10" DataKeyNames="Id" OverrideDataSourceControlSorting="true"
                                     OnNeedDataSource="RadLVPhotos_NeedDataSource" ItemPlaceholderID="ProductsHolder">
                                    <EmptyDataTemplate>
                                        <legend>Photos</legend>Aucune photo...
                                    </EmptyDataTemplate>
                                    <ItemTemplate>
                                        <fieldset style="float: left; margin: 5px 5px 5px 5px; padding: 2px 2px 2px 2px;
                                            background: #eeeeee" class="myClass" onmouseover="containerMouseover(this)" onmouseout="containerMouseout(this)">
                                            <telerik:RadBinaryImage Style="cursor: pointer;" runat="server" ID="RadBinaryImage1"
                                                DataValue='<%#Eval("Fichier.Content") %>' Height='60' Width="60"
                                                ResizeMode="Fit" />
                                            <br />
                                        </fieldset>
                                    </ItemTemplate>
                                </telerik:RadListView>

here the databinding:

    Protected Sub RadLVPhotos_NeedDataSource(ByVal source As Object, ByVal e As Telerik.Web.UI.RadListViewNeedDataSourceEventArgs)
        Dim radLVPhotos As RadListView = DirectCast(source, RadListView)

        If radLVPhotos.Enabled = True Then
            Dim scope As IObjectScope = ScopeFactory.GetPerRequestScope(HttpContext.Current)
            Dim nID As Int32 = Convert.ToInt32(hfID.Value)

            radLVPhotos.DataSource = From ProdFich In scope.Extent(Of ProduitsFichier)() Select ProdFich Where ProdFich.ProdID = nID And ProdFich.EstImage = True
        End If
    End Sub

any suggestion?
Thanks
