I have moved a custom module across from a production server running 6.0.1 to a CE 6.2 server. However, when adding the module and invoking the relevant page, I receive an error as follows. Any idea on why RadComboBox can't be located (this is a fresh CE 6.2 installation).

'telerik:RadComboBox'. ---> System.Web.HttpParseException: Unknown server tag 'telerik:RadComboBox'. ---> System.Web.HttpParseException: Unknown server tag 'telerik:RadComboBox'. ---> System.Web.HttpException: Unknown server tag 'telerik:RadComboBox'. at System.Web.UI.TemplateParser.ProcessError(String message) at

By the way, the relevant ASP.Net server-side code is as follows:

<telerik:RadComboBox ID="rcbCategory" AutoPostBack="false" runat="server"
            EmptyMessage="Type a category" AllowCustomText="false"
            MarkFirstMatch="true"
            Label="I am looking for:" LabelCssClass="light-shadow" Width="262px">
        </telerik:RadComboBox>

The module has been installed on the target server without modification, which suggests that it is not the problem (it works fine on the production server).

Thanks.

Mark
