                                            <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"

                    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
