RadComboBox AutomaticLoadOnDemand issue

[Fit2Page]

We have a serious issue when using this feature, following code generates attached error. It occurs when scrolling or clicking the "Show more results"

 

                                      <asp:SqlDataSource ID="sds_geneesmiddel" ConnectionString="<%$ connectionstrings:lef %>" SelectCommand="select Left(Naam, 70) as Naam, id from geneesmiddel order by Naam" runat="server"></asp:SqlDataSource>

                                                    <telerik:RadComboBox DataSourceID="sds_geneesmiddel" DataTextField="Naam" DataValueField="id"
                EnableAutomaticLoadOnDemand="true" ShowMoreResultsBox="true" EnableVirtualScrolling="true"
                ItemsPerRequest="10" Width="100%" Height="150px" Filter="Contains" EmptyMessage="Typ de naam" DropDownAutoWidth="Enabled" ID="rcb_geneesmiddel" runat="server">
                                                  
                                                    </telerik:RadComboBox>

 

This is something I have to solve today, please react urgently.
